The settings are stored in battery-backed CMOS Memory that retains information about your system when the power is off. To enter the Setup Utility, press <F1> when the prompt to do so appears on the screen shortly after your computer is turned on (during what is called the Power On Self Test (POST) process). After a moment, the Main Setup menu appears: Notice a separate box on the right side of the screen. This is the Command Screen, and it is displayed as part of every window in the Setup utility. It contains commands in white text that help you move through the Setup functions that are presented in black text. Help Command — Press <F1> to retrieve information about highlighted items. in submenu screens. Back Command — Press <Esc> to back out of any menu field. Select Command — Press <Enter> to select submenus and options. Previous Item Command — Press the Up Arrow to move up the list of menu items. Next Item Command — Press the Down Arrow to move down the list of menu items. Select Menu Command — Use the Left and Right Arrows to move among the four major menus. Setup Defaults Command — Press <F5> to set the Setup Utility to its factory default values. Previous Values Command — Press <F6> to set all Setup Utility values as they were when you entered the Setup Utility. Save & Exit Command — Press <F10> to exit the Setup Utility.   Using the Main Setup Menu Return to the Main Setup menu and look at the options. Several items of information in this menu tell you about your system. You can change some of the items. Others are provided solely for your information.   System time and date These fields provide you with the current date and time. Note that the hour is displayed as a 24-hour clock. For example, 1:00 PM is 13:00:00.   Floppy options Highlight this item and press <Enter> to view the floppy drive options submenu. This submenu provides you with information about the floppy disk drives that may be installed in your system. Press <Enter> on the highlighted floppy drive type to see its options submenu. You should only change the floppy drive type if you have installed another floppy drive shown on the is, wish to disable floppy disk support, or if CMOS values are lost.   Primary/Secondary IDE device setup Your system board can support two IDE devices (hard drives, CD-ROM drives) on the system board primary IDE connector, and two more on its secondary IDE connector. Highlight the first hard drive item, called Primary IDE Master, and press <Enter>. The Primary IDE Master information submenu appears (See the Primary IDE Master submenu). The IDE device configuration default setting is Auto Configured, which allows the computer to detect and set up any IDE device If the IDE device is changed while the power to system is off, the Setup Utility detects the new IDE devices and sets the devices’ proper settings. You can change the hard drive type to User Definable by pressing <Enter> on the highlighted bar. You may need to choose the User Definable mode if you are running Novell and have a 528MB or larger size drive. Highlight User Definable and press < Enter>. Now you can fill in the fields with your specific information found in your hard drive documentation. For example, set the drive to 4960 cylinders, 16 heads, and 63 sectors. The size shows 1549MB. You can also change the device type to Disabled. Choose this setting to disable BIOS support for an IDE device. IDE Translation Mode controls the way your system interacts with the hard drive in terms of the drive size, capabilities, and the operating system that it uses. The default setting is Auto Configured. This allows the BIOS to detect automatically the proper translation mode. Select Standard CHS if the system is using a 528MB or smaller hard drive that does not support Auto detection, or if the operating system does not support Logical Block Addressing (LBA) or Extended CHS translation modes. Select Extended CHS if the system is using a hard drive larger than 528MB. Check your hard drive manual to determine which of these modes your hard drive supports. Some operating systems do not support LBA and/or Extended CHS translation modes. In these cases, this parameter should be set to Standard CHS. Check the documentation for your specific operating system to see if it supports these extended modes. MS-DOS, Windows 3.X, and Windows 95 all support LBA and Extended CHS modes. Multiple Sector Setting controls the number of sectors transferred by an IDE drive per interrupt generated. The default setting is Auto Configured. Press <Enter> on the Multiple Sector Setting field to see the other options: Disabled, 4 sectors/Block, or 8 sectors/Block. Check the specifications for your hard disk drive (found in its documentation) to determine which setting provides the optimum performance for your drive. Fast Programmed I/O Modes controls the speed at which programmed I/O transfers occur on the PCI- IDE interface. The default setting is Auto Configured, which causes transfers to occur at the maximum speed supported by the drive. Highlight the second hard drive item, called Primary IDE Slave, and press <Enter>. All of the fields shown on this submenu function the same as those listed on the Primary IDE Master screen.   Language This field controls the language of the text strings used in the Setup Utility and in reporting system errors. Any installed language appears as an option in its own language.   Boot Options Highlight First Boot Device and press <Enter> to see the submenu, in which you can select several parameters that affect the computer’s bootup configuration. Boot Device fields (First through Fourth) allow you to choose the order in which your computer selects a boot device. You choose the device you want for each field by pressing <Enter> to view the choices. Note: No two Boot device fields can be set to the same option. The default Boot Device order is as follows: Floppy, 1st IDE HD, and Disabled. Make sure any unused Boot Device fields are set to Disabled. The Display Gateway 2000 Logo field controls whether or not the Gateway Logo is displayed during boot up. Yes displays the logo at boot. No turns it off. Note: If you place an older video adapter in your PC, the logo may be displayed incorrectly. Turn off the Logo display to avoid any conflicts. The Logo Effects field is displayed only if the Logo is displayed. The logo scrolls across the screen if it is Enabled. The Pause On Config. Screen field allows you to delay the configuration screen displayed on boot up. The System Cache field controls the primary and secondary caches. We recommend leaving it set to Enabled, since setting it to Disabled degrades system performance. The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system boots up. Since the AnyKey keyboard has separate numeric and cursor keys, we recommend you set this to On. However, the factory default setting is Off. The Setup Prompt field controls whether the "Press <F1> to Enter Setup" message is displayed during POST. Enabled is the default setting; the Disabled setting shuts off the "Press <F1> to Enter Setup" message during POST. The Hard Disk Pre-Delay field delays the computer’s attempt to initialize the first IDE drive in that system. This is necessary because some drives may hang if they are accessed too soon following power up or reset. This delay only affects the first drive to be accessed. Disabled is the default setting. The other options are 3, 6, 9, 12, 15, 21, or 30 seconds. The Typematic Rate Programming field controls whether or not your system uses default or user configurable values for two subitems: Typematic Rate Delay and Typematic Rate. Since the 104+ keyboard has typematic functions built in, you can set this to Default. If you choose Override, the following two sub items appear: Typematic Rate Delay. This item sets how long a key must be held down before it begins to repeat. It is functional only if Typematic Rate Programming is set to Override. Typematic Rate. This item sets how fast a key repeats. It is functional only if Typematic Rate Programming is set to Override. The Video Mode field is for information only. It tells you the computer’s video mode. The Mouse field is for information only. It describes whether or not you have a PS2 mouse Installed or Not Installed. The Base Memory field is for information only. It reports the amount of conventional memory in your system, normally 640 KB. The Extended Memory field is for information only. It should report your total RAM above the first 1MB.   Using the Advanced Setup Menu Use the Right Arrow to toggle to the next menu, the Advanced Setup menu. The Processor Type is an information-only field that describes the processor type installed, normally Pentium® Family. If an MMX processor is installed, that information is displayed in this field. The Processor Speed field is for information only. The Processor Speed item displays either 90, 100, 120, 133, 150, 166, or 200 MHz, depending on the jumper block configuration setting for the CPU speed. The Cache Size field is for information only. Cache size item displays the size of the installed cache. Cache size is automatically detected. The size is 512K. If, however, the CMOS is cleared, the Setup program reports 0K until the computer is rebooted. The Bank 0 DIMM Detected and Bank 1 DIMM Detected fields automatically detect and display installed memory DIMM types, EDO or SDRAM.   Peripheral Configuration By pressing <Enter> on this highlighted option, you can select the Peripheral Configuration submenu. This submenu allows you to enable or disable several peripherals and on-board resources. The Primary PCI IDE Interface field allows you to enable or disable the primary IDE hard drive/CDROM interface. You can choose Enabled or Disabled. The default setting is Enabled. The Secondary PCI IDE Interface field allows you to enable or disable the secondary IDE hard drive/CDROM interface. You can choose Enabled or Disabled. The default setting is Enabled. The PCI IDE Bus Master field allows you to enable or disable Bus Mastering. The Floppy Interface field allows you to enable or disable the floppy diskette drive interface. You can choose Enabled or Disabled. The default setting is Enabled. Onboard Audio controls the integrated sound portion of your computer. The default option, Enabled, activates the integrated sound. The other option, Disabled, deactivates the integrated audio. The USB Legacy Keyboard field allows you to activate or deactivate the USB keyboard support for operating systems other than Windows 95. Enabled activates the support for all other operating systems. Disabled deactivates the USB support. Disabled is the default setting for computers with Windows 95. Note: The options for Serial Port 1 Address and Serial Port 2 Address are the same. See the options depicted on the Serial Port 2 Address graphic for Serial Port 1 Address. The Serial Port 1 Address field allows you to select the address of serial port 1. The default setting is Auto. The Serial Port 2 Address field allows you to select the address of serial port 2. Several options are available. The default setting is Auto. The Serial Port 2 mode field allows you to select Normal mode or Fast IR mode. Normal is the default mode. The Parallel Port Address field allows you to select the address and IRQ of the parallel port. The default setting is Auto. The Parallel Port Mode field allows you to select the mode for the parallel port. The setting you choose depends on the type of peripheral installed with your system. The following illustration displays several options. The default setting is Normal, a Bi-directional, input-output only mode (the parallel port operates in bi-directional PS/2-compatible mode). ECP is an Extended Capabilities Port mode. EPP is an Enhanced Parallel Port mode. Selecting either ECP or EPP means that the parallel port operates in both high speed and bi-directional modes. The Serial Port 1 Status field displays the current status of the serial port 1 address and IRQ indicated in that field. Any changes that you make to the corresponding user configuration fields do not take effect until you save and exit the Setup Utility. The Serial Port 2 Status field displays the current status of the serial port 2 address and IRQ indicated in that field. Any changes that you make to the corresponding user configuration fields do not take effect until you save and exit the Setup Utility. The Parallel Port Status field displays the current status of the parallel port mode indicated in that field. Any changes that you make to the corresponding user configuration fields do not take effect until you save and exit the Setup Utility.   Advanced Chipset Configuration By pressing <Enter> on this highlighted option, you can select the Advanced Chipset Configuration submenu displayed in the next graphic: This submenu allows you to change the characteristics of your computer’s PCI Latency Timer and Video Palette Snoop. The Video Palette Snoop, when set to Enabled, allows an ISA video card to share a common palette with a PCI graphics card. Your system is configured with an integrated PCI graphics adapter, you should leave this item set to its default setting of Disabled. The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus. The default is 64 and should not be changed.   Power Management Configuration By pressing <Enter> on this highlighted option, you can select the Power Management Configuration submenu. The Power Management Support field allows you to enable or disable BIOS support for Advanced Power Management (APM) support. If you choose Enable, the system works with APM-aware operating systems and software to manage the power consumed by the CPU, IDE drives, and graphics cards. Enabling the APM support activates the Fast Start power and power button features. When APM support is active in both the BIOS and the operating system, the Power button function changes. See the "Fast Start Mode Power Management" section for a discussion of the Fast Start features. If you choose Disabled, then none of the other fields in the Power Management Configuration submenu are displayed. The IDE Driver Power Down field controls whether a spin-down command is issued to the IDE drives when the system goes into low power mode. Choose Enabled or Disabled. The VESA Video Power Down field controls the VESA power management command issued to the graphics card when the system goes into low power mode. Several settings are provided in the submenu. The proper setting is dependent upon the VESA mode(s) supported by your graphics card. The Inactivity Timer controls the number of minutes that the system detects no user activity before switching to low power mode. The default setting is 20 minutes. When the computer comes out of the power save mode, it emits three beeps to notify you that it is out of the power save mode. Video may take a few seconds to reappear on your monitor. If you have set a User Password, you must enter that password before the computer comes out of the power-managed state. Instructions for setting a User Password are in the "Using the Security Setup Menu" section. The Fan Always On field overrides APM fan control. The APM fan control turns the fan off any time the computer enters a power-managed state. Set to the Yes option, the fan remains on any time the computer is powered on or in an APM state. If SCSI devices are detected in the computer, the fan remains on.   Fast Start Mode Power Management The Fast Start Mode is an enhanced feature of this system board. It enables the user to put the computer into a "power save" (sleep) mode by pushing the power button. The computer appears to be completely off. To return it to its state prior to entering the "power save" mode, push the power button again. The table below summarizes the operation of the power button. These instructions are also noted on the sticker on the front of your case. A detailed description of these instructions is shown after this figure. System Status From To Action LED (Power) OFF ON Push power button Green ON Sleep Push power button Amber Sleep ON Push power button Green ON OFF Push and hold the power button for 5 seconds OFF   How to reset your computer with PM enabled: Push in the power button and hold for five seconds. Push in the power button again to turn on the computer. If Power Management Support is Active, the power button operates differently from when Power Management Support is disabled. If Power Management Support is Active: From the OFF state, pressing the power button turns on the system. The system goes through the POST routine and boots into the operating system. The power LED turns green. From the ON state, pressing the power button sends the system into "POWER SAVE" (sleep) state. During this state the system appears OFF to the user, draws very little power, and the power LED turns amber. From the "POWER SAVE" (sleep) state, pressing the power button returns the PC to the same ON state that existed before going into the "POWER SAVE" (sleep) state. This occurs without the computer going through the boot routine. This is Fast Start Mode and the power LED turns green. This enables the user to return to the application or file in use before the "POWER SAVE" (sleep) state was activated. From the ON state pushing the power button and holding it for more than five seconds shuts down the PC completely and the power LED goes off. (Note: With the Fast Start Mode, you do not need to turn off the PC completely). To RESET the computer when it is locked up, try pressing the <Ctrl>, <Alt>, and <Del> keys simultaneously. If this does not work, push and hold in the power button for five seconds to turn off the PC. Push the power button again to power up the computer. To shut down the PC immediately when it is going through the POST routine, push and hold in the power button for five seconds. Note that if the power button is given a short (less than five seconds) push, the PC remembers that the button has been pushed, and it shuts down the computer just before the computer enters the operating system. To shut down the computer when you are in the SETUP utility, push and hold in the power button for five seconds to shut down the system. If Power Management Support is DISABLED: From the OFF state, press the power button to power on the system. From the ON state, press the power button to shut down the system.   Plug and Play Configuration Press <Enter> on this highlighted option to select the Plug and Play Configuration submenu. Note: The Plug and Play Configuration screen is dynamic. The available IRQs change according to the peripherals installed and the IRQs that the peripherals use. This submenu allows you to match system configuration to level of Plug and Play support provided by the operating system. The Configuration Mode field allows you to choose the method in which information about legacy ISA cards (ISA cards that are not Plug and Play aware) is conveyed to the operating system, allowing the system software to set up PCI and ISA Plug and Play cards without conflicting with the legacy ISA cards. Press <Enter> with the Configuration Mode field highlighted to access the submenu options. If you choose Use Set Utility, the BIOS depends upon information provided by you to prevent conflicts between Plug and Play cards and legacy ISA cards. If you choose this option, you should not install and use run-time Plug and Play software utilities. (Configuration Manager and ICU). If you choose Use ICU then the BIOS uses the information provided by the run-time Plug and Play software utility (Configuration Manager and ICU) to ensure no conflicts with legacy ISA cards. Choose this option only if you are using MS-DOS or Windows 3.x. If you choose Use PnP OS, you must use a Plug and Play aware operating system (Windows 95). The ISA Shared Memory Size field is used to specify a range of memory addresses that are directed to ISA legacy cards. This field should be set to a memory size (16KB, 32KB, etc.) only when a non-Plug and Play ISA card (legacy card) is used that has its own non-ROM memory space. Local Area Network (LAN) cards that have on-board memory buffers are one example of this. Video capture cards that have video buffer memory are another. The default (Disabled) is for all upper memory may be accessed by Plug and Play devices. Note: If you choose an option other than Disabled, a second field appears. This field displays a corresponding base address for the memory size you selected. You have the option to change the base address for all memory options except 96KB, because this option takes up the entire memory block. The IRQ and DMA fields are used to indicate whether individual interrupts and DMA channels are used by ISA legacy cards. If not used, then they should be set to PCI/Plug and Play/ISA. If they are used, they should be set to ISA Only. It is important to remember that all but one IRQ can be set to Used by ISA Card. At least one IRQ must remain available for the PCI bus and for PCI cards that use interrupts to function. The Reserve I/O space field allows for 2 through 64 bytes of I/O space to be reserved for ISA legacy resources. The Shared PCI IRQs field forces 1 or 2 IRQs for allocation to PCI devices. If Auto is selected for this field, the BIOS does not restrict the number of IRQs used by PCI devices.   Using the Security Setup menu In this menu, you can set two types of passwords for your Security Setup program. The two types of passwords are User Passwords and Administrative Passwords. The Set User Password allows you to set a password to control access to the Setup Utility, the keyboard initial boot, and the keyboard when used along with the Security Hot Key. The Administrative Password allows an administrator (one with the knowledge of the Administrative Password) to limit or to deny access to non- administrators. The following Setup fields are accessible to administrators only. They are not displayed if an Administrative password has not been set. Access Modes: Allows the administrator to set the level of Setup Utility access allowed to non- administrators. Unlimited Access: A non-administrator can access all Setup Utility fields except administrator-only fields. Limited Access: A non-administrator can access Time, Date, and User Password fields only. A non-administrator can view other fields, but they cannot change them. View Only: A non-administrator can view all Setup Utility fields, but cannot change any fields. No Access: Access to the Setup Utility without an Administrative Password is not allowed. Delete User Password: Allows an administrate to delete a User Password. This field is displayed only if both an Administrative Password and a User Password have been set. The following table describes the interaction between these passwords: Password in Effect Enter Setup with User Password Enter Setup with Admin Password Boot User Password only Can change all fields N/A User Password required Admin Password only N/A Can change all fields No Password required Both Can change limited number of fields Can change all fields User or Admin password required When you press <Enter> on the highlighted Set User Password field, the Set User Password submenu appears: Enter your password in the Enter New Password block. Then, retype it in the Confirm New Password block. Your password is now set. The previous window above is for Set User Password, but it appears the same for Set Administrative Password. You can tell if a password has been set in either of the two fields by looking at the top of the Security menu screen. If either the User Password or Administrative Password fields report Installed, then a password is in place for that field. If you are entering a new password in either field to replace an older one, the pop-up window looks about the same, except the words Enter Current Password appear at the top. If you have set a password in the User Password field, an additional field, Unattended Start, appears. This field controls the point at which you must enter the User password. If you choose Enable, you must give the User password after the system has completed automatic boot activity and before you can use the keyboard (the keyboard is locked and the NUM LOCK, CAPS LOCK, and SCROLL LOCK lights are flashing). If you choose Disable, you must give the password before the system starts automatic bootup. Another field you see if you have entered a User password is the Security Hot Key (CTRL-ALT-) field. Use this field to define a key that, typed simultaneously with <Cutler> and <At>, places the system into secure mode by locking out the keyboard. When you type in the Security Hot Key, the Numb Lock, Caps Lock, and Scroll Lock lights on your keyboard flash on and off in sequence, indicating that your system is now secure.   Setup Exit Menu This menu allows you to choose whether to keep any changes in the Setup Utility that you may have made before exiting. If you press <Enter> on the Exit Saving Changes field, the Exit Saving Changes screen appears: The Exit Saving Changes field allows you to exit the Setup Utility and save the current entries for all parameters. If you press <Enter>, the system exits Setup with all the parameters set to their current values. If you press <Esc>, you return to the Exit menu without saving any changes. The Exit Discarding Changes field allows you to exit the Setup Utility and discard any changes you may have made to the Setup parameters.If you press <Enter>, the system exits Setup and throws out any changes you made to the parameters. If you press <Esc>, you return to the Exit menu with no change. The Load Setup Defaults field allows you to load factory default values into all Setup parameters, except for passwords. If you choose <Enter>, the factory defaults are loaded into all Setup parameters, except for passwords. If you choose <Esc>, you return to the Exit menu with no change. The Load Setup Defaults option is available only if you are an administrator (if you have set up an administrative password) or if you have User unlimited access you can load the factory default Setup Utility settings.   The System Board This chapter discusses the features and connection points for your system board. It also details different configuration options for memory and processor speed. Before opening your system case, read and follow these preventions and precautions to prevent damage from static electricity. Caution! Preventing Static Electricity Damage The components inside your system are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Static electricity can cause irreparable damage to your system; however, if you follow these preventions and precautions, you should prevent such damage. Static Electricity Preventions 1. WEAR A GROUNDING WRIST STRAP (available at most electronic stores). 2. Turn off the system power. 3. Touch the back of the power supply fan, located on the back of the case. 4. UNPLUG ALL CORDS FROM WALL OUTLET. 5. Remove the system case cover. Static Electricity Precautions • Avoid static-causing surfaces such as plastic and styrofoam in your work area. • Remove parts from their antistatic bags only when you are ready to use it. Do not lay parts on the outside of antistatic bags since only the inside provides antistatic protection. • Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots. • Never slide cards or other parts over any surface.   Removing the cover Computers emit radio frequency energy that can interfere with television and radio reception if not contained. Do not operate the computer with the cover removed.   To remove the cover: Follow the preventions and precautions to prevent damage from static electricity. Remove only the screws that hold the cover in place. Refer to the documentation that shipped with your computer for instructions. Do not remove any other screws. Carefully remove the cover. When you replace the cover, be careful not to remove or damage any brass tabs that may be around the edge of the unit, and do not catch the cover on any cables inside the unit. The system board has six expansion slot connectors. Three connectors are ISA-bus 8/16-bit slots. Three connectors accept expansion cards with a 32-bit PCI local bus interface. This system board accepts two types of expansion cards: ISA and PCI cards. Some ISA expansion cards have jumpers or switches that set interrupts and I/O addresses, and they have instructions that explain how to set them to avoid conflicts; follow the instructions carefully. If you install a PCI card, simply plug it in. Refer to the system board illustration on the next page for the proper installation location. The operating system configures the card for you.   To install an expansion card Set any jumpers and switches on the card if required in the card’s instructions. Power down the system and remove the cover. If you have a tower case, lay the unit on its side to make access to the interior easier. Locate a free expansion slot. Remove and retain the screw securing the expansion port cover to the rear panel. Keep the port cover to re-install if you ever remove the card. Seat the expansion card firmly in the slot. Secure the card to the rear panel with the screw from step 5. Attach any cables according to the card’s instructions. Replace the system unit cover. Install any software that the card may require.   System board connectors Power connector Floppy connector Primary IDE connector Secondary IDE connector Front panel I/O connectors 3V Lithium battery J28; J29 ISA expansion slots PCI expansion slots TV tuner connector (top); TAD connector (bottom) MIDI/joystick connector (top); audio connectors (bottom) Parallel port (top); COM1 serial port (bottom left); video connector (bottom right) USB connectors (stacked) PS/2 mouse and keyboard connectors (stacked) CD audio connector JB1/J21 jumpers CPU in a ZIF socket DIMM slots Fan connector   Back-panel connection points USB connectors (stacked) 25-pin parallel port (LPT1) MIDI/joystick connector Microphone connector Audio line-in connector Audio line-out connector (speakers) 15-pin video connector (monitor) 9-pin serial port (COM1) PS/2 mouse and keyboard connectors (stacked)   Cable routing To reduce emissions to a minimum, we recommend routing the floppy cable and the IDE device cables in a certain manner. The following illustrates the correct routing for these cables. IDE cables Whenever you open your computer’s case and work with components on the system board, route the cables as noted in the preceding graphic.   System board connection descriptions   Expansion slots Up to six expansion slots may be populated on the system board. There are three ISA bus expansion connectors and three PCI expansion connectors. All three PCI expansion slots accept PCI bus master cards only, and fully support the PCI 2.1 specification.   Battery This external coin-cell style battery supplies power to the integrated real time clock (RTC) and CMOS memory. The battery has an estimated lifetime of three years and is socketed for easy replacement. When the system is on, power is supplied from the power supply to extend the life of the battery.   DIMM sockets One DIMM socket comprises a bank. You can fill one or both banks with DIMM components, in combinations listed according to the charts in the "Installing Memory" section of this manual.   Power connector This single-unit connector supplies power to the system board components and cooling fan. It is keyed to fit only one way.   Fan connector This connector allows the system software to control the fan, turning it on or off thus overriding the power connector.   J28 Flash Update Jumper This allows the BIOS to be updated if the BIOS has become corrupted or has been improved. A plastic jumper shunt covering Pin 2 is for normal operations; a plastic jumper shunt connecting Pins 1 and 2 is for BIOS recovery.   J29 Password, Setup Utility, NVRAM Clear Settings Jumper This allows the password, system setup, and NVRAM to be cleared. A plastic jumper shunt covering Pin 2 is for normal operations; a plastic jumper shunt connecting Pins 1 and 2 is for clearing the password setup and NVRAM. To clear NVRAM without clearing the system setup utility and the password, turn on the computer holding the <N> and the <Ctrl> keys simultaneously. This method does not work with USB keyboards or keyboards connected to the computer through a switchbox.   Stacked connectors The keyboard and mouse; parallel port, video, USB, and COM1 connectors; and joystick/MIDI and audio connectors are stacked on this system board.   Front panel I/O connectors Speaker (on-board Piezo or external speaker) Reset switch Power and Sleep LED Hard drive activity LED Infrared port Power on/off   Jumper settings The jumper configuration blocks on the system board allow you to alter several system functions. Use the illustrations on the following pages to set the jumpers according to the functions you need to use. The jumpers were set to their default positions at the factory, so you need to alter the jumpers only if you are changing a function.   Jumper settings for system speeds The following illustrations show the correct jumper settings on the JB1 and J21 jumpers for the 200 MHz processor speed. Processor speed jumpers: JB1 (left), J21 (right) In addition to the 200MHz processor speed, the system board also supports a variety of other processor speeds. The chart in the next section describes these additional settings.   Jumper settings chart for processor speeds Below is a complete list of jumper settings and the resulting processor speeds, memory clock speeds, and CPU clock multiplier. You can use this chart to further customize your system to best fit your computing needs. Be sure that the processor on the system board matches these settings.

To clear the settings, shut down the computer and move the jumper shunt on the J29 jumper block from its default position (pin 2, shown in the illustration) to pins 1-2. Turn on the computer and the password, Setup Utility, and NVRAM are cleared. Then, shut down the computer again and replace the jumper shunt to its normal operating position. This procedure should only be performed if you have forgotten your user password or wish to clear NVRAM and Setup Utility because you believe that they are corrupt or malfunctioning. 1. Password/Flash Update jumpers: J28 (top), J29 (bottom)   Flash update The preceding illustration shows the jumper pin settings for the flash update function and the normal operation function. To update the flash BIOS, power down the system and move the jumper shunt on from pin 2 on jumper J 28 block from its default position (pin 2, shown in the preceding illustration) to pins 1-2. Start up the system and the CMOS is reset to its default values. Then, shut down the system again and replace the jumper shunt to its normal operating position. This procedure should be done whenever the system BIOS is updated.   Installing memory Your computer’s system board supports Synchronous Dynamic Random Access Memory (SDRAM) and Dual In-line Memory Modules (DIMMs). DIMMs represent an advancement in memory capability because they provide a 64-bit data path that allows for greater data transfer across the system board. The previous type of memory, Single In-line Memory Modules (SIMMs), provides only a 32-bit data path. Two DIMM sockets reside on the system board, arranged as Bank 0 and Bank 1, with each bank consisting of one socket. Bank 0 only, Bank 1 only, or both banks may be populated with DIMMs. Bank 1 operates independently of Bank 0, so Bank 0 can be left empty and Bank 1 filled with a DIMM or vice versa. No jumper settings are required for the memory size or type; this information is automatically detected by the system BIOS. This system board requires CL (clock latency) 2, 4 clock DIMMs. Most pre-1997 DIMMs are 2 clock DIMMs. Should you desire to add more DIMMs for your computer, make sure that you purchase CL2, 4 clock DIMMs. Refer to the charts at the end of this section to see all of the possible combinations for SDRAM DIMMs.   To install DIMMs: Pull open the plastic DIMM socket clamps on each side of the socket. Insert the DIMM into the socket as shown below. The module is inserted perpendicular to the socket. Align the two notches in the DIMM with two notches in the DIMM socket. Gently press the DIMM into the socket until it doesn’t move any farther. Inserting the DIMM automatically locks each of the socket clamps on each end of the DIMM.   To remove DIMMs: Gently push out first one and then the other plastic socket clamp on each end of the DIMM. The module should pop up slightly from the socket. Carefully lift the DIMM out of the socket. Never force the DIMM out of the socket without releasing the clamps. Failure to release the clamps may break the socket, causing critical damage.   DIMM Charts DIMM Bank 0 DIMM Bank 1 Memory Total 1M x 64 (8MB) or empty 1M x 64 (8MB) or empty 8MB 1M x 64 (8MB) 1M x 64 (8MB) 16MB 1M x 64 (8MB) 2M x 64 (16MB) 24MB 1M x 64 (8MB) 4M x 64 (32MB) 40MB 1M x 64 (8MB) 8M x 64 (64MB) 72MB 1M x 64 (8MB) 16M x 64 (128MB) 136MB 2M x 64 (16MB) or empty 2M x 64 (16MB) or empty 16MB 2M x 64 (16MB) 1M x 64 (8MB) 24MB 2M x 64 (16MB) 2M x 64 (16MB) 32MB 2M x 64 (16MB) 4M x 64 (32MB) 48MB 2M x 64 (16MB) 8M x 64 (64MB) 80MB 2M x 64 (16MB) 16 x 64 (128MB) 144MB 4M x 64 (32MB) or empty 4M x 64 (32MB) or empty 32MB 4M x 64 (32MB) 1M x 64 (8MB) 40MB 4M x 64 (32MB) 2M x 64 (16MB) 48MB 4M x 64 (32MB) 4M x 64 (32MB) 64MB 4M x 64 (32MB) 8M x 64 (64MB) 96MB 4M x 64 (32MB) 16M x 64 (128MB) 160MB 8M x 64 (64MB) or empty 8 x 64 (64MB) or empty 64MB 8M x 64 (64MB) 1M x 64 (8MB) 72MB 8M x 64 (64MB) 2M x 64 (16MB) 80MB 8M x 64 (64MB) 4M x 64 (32MB) 96MB 8M x 64 (64MB) 8M x 64 (64MB) 128MB 8M x 64 (64MB) 16M x 64 (128MB) 192MB 16M x 64 (128MB) or empty 16M x 64 (128MB) or empty 126MB 16M x 64 (128MB) 1M x 64 (8MB) 136MB 16M x 64 (128MB) 2M x 64 (16MB) 144MB 16M x 64 (128MB) 4M x 64 (32MB) 160MB 16M x 64 (128MB) 8M x 64 (64MB) 192MB 16M x 64 (128MB) 16M x 64 (128MB) 256MB   Installing USB software drivers and reinstalling Ultra ATA drivers   USB software drivers If you buy a USB device, you must install the USB drivers in Windows 95 to gain USB functionality. Your computer shipped with a 3.5" disk labeled, Integrated Controller Ultra ATA files for Windows 95, that you must use to enable the USB software drivers. Please consult the Readme text on the disk for installation instructions.   Ultra ATA drivers These drivers are installed on your PC. If you ever need to reinstall Windows 95, you must reinstall the Ultra ATA drivers after your Windows 95 installation. Your computer shipped with a 3.5" disk labeled, Integrated Controller Ultra ATA files for Windows 95, that you must use to reinstall the Ultra ATA drivers. Please consult the Readme text on the disk for installation instructions. To reset your computer’s IDE hard drive(s) and IDE CD-ROM drive(s) to Ultra ATA mode, please consult the following instructions. Your computer is configured for maximum performance using the Ultra-ATA mode. However, if you reinstall Windows 95 software on your PC, if you have reformatted your hard drive and are reinstalling Windows 95, or if you have added a hard drive or a CD-ROM to your system, please follow this procedure to set your hard drive and CD-ROM to or back to Ultra-ATA mode.   To set a drive to Ultra ATA mode: Turn your system on booting to Windows 95. Right-click My Computer. Click Properties, then Device Manager, then the Plus Sign (+) next to Disk Drives or CD-ROM, depending on which devices that you want to set to Ultra-ATA mode. Note: Your PC’s IDE hard drive and IDE CD-ROM may use the Ultra-ATA mode. You should follow this procedure for each IDE hard drive and IDE CD-ROM drive in your computer. For the CD-ROM, double-click the CD-ROM icon with a specific CD-ROM name following it that appears below the generic CD-ROM icon. Then go to Step 5. For the hard drive, double-click the hard drive icon that appears below the Disk Drives icon labeled, Generic IDE Disk. Click the Settings tab, then click in the box next to the word DMA. The box should be filled with a check mark. If the word DMA does not appear under in Options box in the Settings Tab, your device does not support Ultra-ATA mode, or if you have reinstalled Windows 95 refer to your installation instructions on the Readme file on the Integrated Controller Ultra ATA files for Windows 95 disk. Click on the OK button. The System Settings Screen should appear requesting that you turn off your computer and configure your hardware. Click Yes, when your system turns off, turn it back on and your device should operate in Ultra-ATA mode.   On-board Audio Your system board has its audio adapter integrated into it. The audio utilities and software are already installed. This chapter provides information about the different audio utilities and how to reinstall them should that become necessary.   Using AudioPCI with Windows 95 games AudioPCI is compatible with all of the popular sound standards on the market. Games that support the following sound modes operate on the AudioPCI chipset: AudioPCI, DirectX, Soundscape, SoundBlaster Pro I, AdLib and MPU401/Roland (Sound Canvas/General MIDI or MT32/LAPC-1). Three operating modes are available for playing games with the AudioPCI: Windows 95 Mode Windows 95 DOS Box Windows 95 DOS Mode. Windows 95 mode is the native mode of the AudioPCI chipset. Games indicating that they are for Windows 95 use this mode. In general, the only requirement to play a game under Windows 95 is to install the game. Double-click on the speaker icon in the right corner of the taskbar to access the Audio Mixer designed for use with AudioPCI. The new mixer accommodates some of the additional features found with AudioPCI. Mute Advanced Help The sliders adjust balance and volume levels, advanced buttons access additional option screens and mute buttons mute each function. Experiment with different settings to find the ones that work the best for you.   Wave device The wave device advanced option adds a spatial enhancement effect, emulating surround sound.   Microphone device The microphone advanced option offers microphone boost and microphone monitor options. The boost options adds a 30dB audio gain to the microphone. This is an audio gain only and does not affect power to the microphone. The monitor option allows you to hear anything spoken into the microphone through the system’s speakers. Deselecting this option could eliminate feedback with some full duplex internet phone applications. You can still be heard, but you won’t hear yourself through the system speakers.   MIDI/Synthesizer device The MIDI/synthesizer device advanced options can add spatial, chorus, and reverb effects. The spatial effect emulates surround sound. The chorus effect adds depth to the synthesizer sounds. The reverb effect makes the MIDI instruments sound like they are playing in a large concert hall.   Using AudioPCI with DOS games AudioPCI is compatible with many of the popular sound standards on the market. Games that support the following sound modes operate on the AudioPCI chipset: AudioPCI, DirectX, Soundscape, SoundBlaster Pro Island AdLib, MPU401/Roland (Sound Canvas/General MIDI or MT32/LAPC-1). The AudioPCI Legacy Device must be enabled for DOS Box games to function. Note: You can find more information about launching DOS games in Windows 95 in the documentation that shipped with your computer. You can launch DOS games two ways in Windows 95: using a DOS session or using DOS Exclusive Mode. The DOS session method of launching games yields the best AudioPCI performance and is strongly recommended as the method of choice.   Using a DOS session The best way to launch DOS games is from a DOS session under Windows 95. Start by viewing Soundscape’s DOS settings (DMA, IRQ, and Address settings). This information allows you to make appropriate choices when you set up the game.   To view the DOS settings: Click the My Computer icon. A menu box appears. Right click Properties. The System Properties screen appears. Click the Device Manager tab to access the page and bring it to the front. Double-click the Sound, video and game controllers icon to see the list of devices. Double-click the ENSONIQ AudioPCI Legacy Device icon. The ENSONIQ AudioPCI Legacy Device Properties screen appears. Click the DOS Settings tab to view the settings. Record all settings for future reference when setting up a game under DOS.   To launch a DOS game: Click Start, Programs, and MS-DOS Prompt. The DOS window appears. Be sure to set up your game based on the DOS Settings page of the ENSONIQ AudioPCI Legacy Device Properties screen to insure proper performance. See the instructions that came with the game for more specific information on running the game.   Using DOS Exclusive Mode At times you may not be able to run a game using a DOS session. The game may be incompatible with Windows 95, or you may not have enough system resources to play with Windows 95 loaded. When these situations arise, you can use a mechanism called DOS Exclusive Mode, which loads only the real-mode portions of the operating system.   To use MS-DOS Exclusive Mode: Click Start, then Shut Down. The Shut Down Windows screen appears. Click Restart the computer in MS-DOS mode?. Click OK. This unloads the Windows 95 GUI and puts the program in DOS Mode.   How MS-DOS Mode works When a user selects "Restart the computer in MS-DOS mode," Windows 95 uses a Program Information File (PIF) named "Exit to MSDOS.PIF." This PIF contains the information needed to shut down Windows and properly configure the system for MS-DOS mode. AudioPCI however, initializes in the AUTOEXEC.BAT file before Windows 95 even loads. During a Windows 95 session, the MS-DOS Mode is inactive. When MS-DOS Mode is entered, the driver becomes active. This ensures that AudioPCI is initialized even if you use an alternate method for reaching MS-DOS Mode (i.e. a shortcut to an MS-DOS application or pressing <F8> during system boot to access the system boot menu).   INITAP.BAT The applications disk installation creates an INITAP.BAT batch file in your AudioPCI directory that allows you to easily set up the AudioPCI hardware in DOS Exclusive Mode. The following describes the added lines. SET SNDSCAPE=<SNDSCAPE.INI location> The SNDSCAPE environment variable points to the location of the SNDSCAPE.INI file. This file is installed when you install the Windows 95 driver. It typically resides in the Windows directory (i.e., SET SNDSCAPE=C:\WINDOWS). The AudioPCI. INI file is used for backwards compatibility with AudioPCI devices and should not be removed. SET BLASTER=A220 Ix Dx T1 This is included for SoundBlaster compatibility. The x’s are place holders that are filled in after APINIT is loaded. <AudioPCI™Path>\APINIT.COM APINIT is the AudioPCI DOS driver. It is required for AudioPCI to function properly. Note: APINT.COM requires that EMM386.EXE is loaded to function. The application disk adds the command lines for EMM386.EXE and HIMEM.SYS to your CONFIG.SYS file if these command lines are not already present in the file.   DOS Exclusive Mode utilities AudioPCI includes a number of DOS utilities to make configuring the hardware easier. These utilities require the AudioPCI driver APINIT.COM to be loaded.   APCONFIG.EXE The APCONFIG utility is used to obtain hardware settings and to enable and disable emulation modes on AudioPCI. In some situations, certain games may incorrectly detect your AudioPCI chipset. By using APCONFIG, you can disable certain options to allow the game to correctly identify the hardware. APCONFIG displays: PCI Hardware Settings: Port, IRQ Soundscape Emulation: Base/MIDI port, Wave port, MIDI IRQ, Wave IRQ, DMA SoundBlaster Pro Emulation: Port, IRQ, DMA MPU-401 (GM, Roland MT32/LAPC-1) Emulation: Port, IRQ AdLib Emulation: Port. If the AudioPCI Legacy Device is disabled, APCONFIG indicates this, and it provides only PCI Hardware port and IRQ settings.   APMIXER.EXE Use APMIXER to change the AudioPCI levels. APMIXER has two modes of operation: Command-line mode and interactive mode.   Command-line mode Command-line mode is useful for advanced users who want to set up batch files with particular volume levels. /s: <0-127 adjusts the synth volume /w: <0-127 adjusts the wave volume /c: <0-127> adjusts the CD audio volume /m: <0 or 1> sets the synth MT-32/LAPC-1 mode: 0=off, 1=on /? displays a help screen APMIXER without any options invokes the interactive editor. The interactive editor mode allows you to change the mixer settings with the mouse, TAB, PG UP, PG DN, or arrow keys. The settings for APINIT are independent of the Windows 95 Ensoniq Mixer settings. If the Save As Default button is not used, settings remain in effect only until the system is restarted. Running Windows 95 and shutting down into DOS Mode does not reset the APMIXER. You cannot run APMIXER from Windows 95.   MT-32.EXE MT-32 or LAPC-1 was a popular sound module in the late 1980s (prior to the General MIDI standard), which provided superior sound over the PC sound systems that were available at that time. During that period, many game manufacturers supported the MT-32 as their high-end sound device. AudioPCI provides two sets of patches: a General MIDI compatible patch set and a patch set that emulates a Roland MT-32 sound module. These patches cannot be used simultaneously, so a utility called MT32 is provided to allow you to easily switch from one patch set to another. Use this utility whenever a game supports MT-32 as a music/sound option. The usage for MT32 is as follows: MT32 [ON | OFF] ON selects the MT-32 patch set and OFF selects the General MIDI patch set. Typing MT32 without any arguments (such as ON or OFF) also switches you to the MT-32 patch set. Windows 95 always uses the General MIDI patch. Use MT32 in a batch file to temporarily enable the MT-32 patch set for DOS Box applications. If the Windows 95 MIDI device is opened, the patch set automatically switches to General MIDI. Execute the MT32 command again before the MT-32 patch set is restored.   Installing AudioPCI games In both a DOS session and DOS Exclusive Mode, you generally have to tell the game what type of hardware is installed and what resources (Port, IRQ, DMA, etc.) the hardware is using.   To find resources in Windows 95: Right click the My Computer icon. A menu box appears. Click Properties. The System Properties screen appears. Click the Device Manager tab to access the page and bring it to the front. Double-click the Sound, video and game controllers icon to see the list of devices. Double-click the ENSONIQ AudioPCI Legacy Device icon. The ENSONIQ AudioPCI Legacy Device Properties screen appears. Select the DOS Settings tab. You can use the information in this screen to help you configure DOS games for use with AudioPCI.   To find resources in DOS Exclusive Mode: Switch to your AudioPCI directory and type: apconfig Some older games may have difficulty detecting the AudioPCI chipset at certain resource settings. Typically, these games would expect the card to be at a fixed set of resources and would fail to load if not detected. If you have any older DOS games that do not work properly, try moving the AudioPCI to a different resource. Use the following table as a guide Problem Resource The SoundBlaster Pro emulation is not recognized. Try changing the AudioPCI wave IRQ between 5 and 7. Use DMA channel 1 and Wave port 220. The Soundscape emulation is not recognized. Try using Base/MIDI port 330, Waveport 534, Wave and MIDI IRQ 5 or 7, and DMA 1. The MPU-401 emulation is not recognized. Try using port address 330. .   Selecting the best game sound option Most DOS-based games that provide sound have some procedure for sound setup. These procedures generally present you with a list of popular sound cards or sound devices. AudioPCI works with one or more of the available options. Differences exist, however, in the way games present sound options. Some may present a single option that corresponds to a particular sound device. (e.g., AudioPCI, SoundBlaster Pro I, Roland Sound Canvas, etc.). Others provide a separate music and digital audio option, either as a single menu selection or as two separate menus (e.g., General MIDI music with SoundBlaster Pro I digital audio, etc.). Some game programs allow you to set the MIDI port address and IRQ for music and sound. Make sure that these settings correspond to the selections made in the Hardware Settings screen of APINIT. If the game offers MPU-401 General MIDI or MT-32 as options and allows you to set the MIDI port address and/or IRQ, make sure they match the MIDI Port Address and IRQ settings in the MIDI Interface section of the Hardware Settings screen. If the game offers SoundBlaster settings, make sure that they correspond to the SoundBlaster/Wave settings in Hardware Settings screen. Remember that AudioPCI emulates a SoundBlaster only at a fixed base port address of 220H. Also, AudioPCI software emulates a SoundBlaster board with a 2.0 DSP. Generally, when you set up a game that does not have direct AudioPCI support, you should choose SoundBlaster as your digital audio option. However, in some instances selecting SoundBlaster Pro may improve digital audio playback. Experimentation with the SoundBlaster settings is the best way to determine if you can select SoundBlaster Pro as an option.   Music options Most DOS games offer a menu choice for sound when they start up. AudioPCI supports all of the popular music options. The only time you need to provide instructions to AudioPCI is when MT32/LAPC-1 is offered and Sound Canvas/General MIDI is not. Because General MIDI provides the highest quality sound, the majority of today’s popular games offer it as an option. Those that do not, almost always offer MT-32 in its place. If you have a choice between General MIDI and MT-32, always choose General MIDI, since it provides you with the best sound quality. If you need to use MT-32, you must first switch from the General MIDI patch set (the default) to the MT-32 patch set. When you are finished using the MT-32 patch set, be sure to switch back to the General MIDI set.   Digital audio options AudioPCI supports AudioPCI digital audio (applications that provide this option are commonly denoted by an AudioPCI logo someplace on the package), SoundBlaster digital audio emulation and Windows Sound System. If an application provides all three as options, specify AudioPCI digital audio as your first choice, SoundBlaster for your second, and Windows Sound System as your third choice.   Troubleshooting The secret to troubleshooting is to examine the evidence you have, gain as much information as you can, and eliminate possibilities one by one. In most cases, the source of the problem soon becomes clear. Often, problems are simple: bad cables, things not plugged in or turned on, etc. Check the obvious first, not last.   Configuration Adding new hardware and software to your computer requires ensuring that nothing conflicts with your existing system. If you have difficulty with the installation procedure or are unable to make the card work, a conflict may be present. Three major configuration settings are possible: I/O Port Address, Interrupt Request (IRQ), and Direct Memory Access (DMA) channels. Even though the AudioPCI chipset is Plug and Play compliant, the presence of other legacy cards can still cause resource conflicts. To resolve such conflicts, it is important to know the settings of other cards (it is best to remove other sound cards) and peripherals currently in your system, including the mouse, fax-modem, video adapters, etc. Many peripherals come with setup software similar to AudioPCI that let you see and change the current configuration. The AudioPCI software also includes utility programs that investigate and report on the configuration of your system and its peripherals. In either event, make a record of the settings used by all the peripherals in your system for reference when installing new hardware and software or troubleshooting problems. Generally, you have a DMA conflict only if your system contains another sound card or an external CD-ROM drive.   DMA channels Under Windows, AudioPCI is capable of full duplex. This means that AudioPCI can play back one.WAV file while recording another. In order for this to happen with older Soundscape legacy cards, two DMA channels have to be dedicated. The PCI bus allows full duplex without any DMA channels. No microphone support is necessary for MS-DOS Mode, so only a single DMA is required for legacy emulation.   Two sound cards Having another sound card in your system in addition to the AudioPCI chipset greatly increases the chances of having system conflicts.   Changing volume and balance levels. To make adjustments to the volume and balance levels, double-click the speaker icon on the right side of the taskbar to access the Audio Mixer.   To add/remove the audio mixer to the taskbar: Click Start, Settings, and Control Panel. The Control Panel screen appears. Double-click the Multimedia icon. The Multimedia Properties screen appears. Click the box next to Show volume control on the taskbar in the Audio tab to add this shortcut to the taskbar.   Audio If you are satisfied that the AudioPCI software is properly installed with no conflicts, but you hear no sound at all, the problem may be with your audio connections. Here are some suggestions: Try playing both a.WAV file and a.MID file to ascertain that no sound is coming from the speakers. If you hear one and not the other, the problem is internal and has nothing to do with your audio system. Be sure that your speakers are properly set up. Try connecting a sound source other than AudioPCI, such as an audio CD player to establish whether or not you can hear it. Be sure that the sound card is properly connected to the monitoring system (a 1/8 mini-phone cable should be running from AudioPCI’s Line Out connector to a line input on the monitoring system). To eliminate the possibility of a bad cable, try plugging a pair of high-impedance headphones (such as most Walkman-type phones) to the AudioPCI Line Out jack to try to hear any sound output.   Microphone For ease of installation, we recommend that you use a dynamic microphone. These require the least amount of setup. Perform the following steps to be sure that your software is set up correctly for MIC input: Double-click the Speaker icon on the right side of the task bar. The Audio Mixer appears. Make sure that the mute button in the microphone device panel is not selected. Click and drag the sliders all the way up. Click the advanced options button in the microphone device panel and select the Microphone Boost option. Deselect the Microphone Monitor option if you have a feedback problem. If you are experiencing distortion using a dynamic microphone: Right click the My Computer icon. A menu box appears. Click Properties. The System Properties screen appears. Click the Device Manager tab to access the page and bring it to the front. Double-click the Sound, video, and game controllers icon to see the list of devices. Double-click the ENSONIQ AudioPCI device icon. The ENSONIQ AudioPCI Properties dialog box appears. Click the Settings tab to access the page and bring it to the front. Deselect the Microphone BIAS option.   CD audio First, be sure that your CD volume is turned up to maximum in the Audiostation mixer. If you still aren’t getting music, you need to verify that the internal patch cable is connected between your CD ROM drive and the AudioPCI connection on the system board. This is typically a small connector with four wires coming out of it. If it is connected but not working, try unplugging it and reconnecting it to another connector (there are 3 to choose from). If this does not work, the patch cable may be broken or defective.   Games Make sure that you have the game set up in a music option that AudioPCI supports. One way to be sure is to follow the guidelines for choosing game settings. You can obtain the AudioPCI hardware settings by looking at the DOS Settings page of the ENSONIQ AudioPCI Legacy Device driver in Windows or by running the APCONFIG utility in DOS. If the game’s install or setup program does not give you a particular sound option that you know the game supports, (for example, the game’s box and manual specify MT-32, but the game’s install or setup does not support it) try rerunning the game’s install or setup program. If you select a sound option in a particular game and the game’s install program says something like, "Sound card not found, proceed anyway?" choose Yes. In some cases, you can still install the program and it works fine. The problem is in the way some install programs check for the presence of sound cards. In order to use two joysticks, you need to use a SoundBlaster-compatible Y-connector, or use an industry-standard MIDI Joystick kit. This makes allowances for the proper direct connections for dual joysticks.   Game crashes If you are experiencing game crashes in games that use DOS extenders, check the sound card’s IRQ. If AudioPCI is set to IRQ 10, that is more than likely the problem. Older DOS extenders have problems dispatching IRQ10 events that occur in protected mode, causing the game to crash.   To change the card’s IRQ: Reboot the system. Press <F1> when prompted to run Setup. Go to the Advanced tab. Set Plug and Play Configuration to Use Setup Utility. Highlight IRQ10 and change it to Used by ISA Card. Save the changes and exit. AudioPC I finds a different IRQ when the system is rebooted.   Installing Ensoniq AudioPCI software The Ensoniq AudioPCI audio functions are built into your system board. The Ensoniq AudioPCI utilities are installed already installed on your system. Observe the following instructions to reinstall your audio software if your audio software becomes corrupt, if it is deleted, or if you must reinstall your operating system.   Reinstalling Windows 95 drivers Use the following instructions to reinstall the driver from the CD correctly.   To install or update the sound driver: Power up the computer to Windows 95. Make sure the Ensoniq Driver Software Disk #1 is in the 3.5" drive. Click Start and Run... and type: a:\setup.exe in the command line provided, then press <ENTER>. The ENSONIQ AudioPCI Install Wizard appears. Note: The specific path to the setup.exe on the disk may vary according to the language necessary. For example: the English path, A:\Win95\english\release\setup.exe. Click the OK button. The ENSONIQ AudioPCI Installation wizard appears. Click Next. Make sure that Remove and Install Software is selected. Click Next. A screen stating that the system is being checked for old drivers appears. Click Next. A screen stating that the latest driver is now to be copied and installed. Note: Steps 8 through 10 occur only if you have deleted Windows 95 from your PC or if you have formatted your hard drive, and you are installing the ENSONIQ AudioPCI software for the first time with Windows 95. If this is not the case, continue at Step 11. You may be prompted to place the Windows 95 CD in your CD-ROM drive. Place the Windows 95 CD in your CD-ROM drive. Click the OK button. The Windows 95 New Hardware Found window appears. Windows 95 cannot find your joystick driver file, msjstick.drv. Click the Browse button. Click the down arrow on the right side of the Drive window and select the CD-ROM drive icon. Click the down arrow on the right side of the Folder window. Double-click the Windows 95 folder. Click OK.

Click Next. The Choose Destination Path screen appears. Click Next to accept the default drive destination. The Restart Computer screen appears. Select Yes, I want to restart my computer now, then click OK.   Reinstalling Windows 95 multimedia extensions Windows 95 includes a number of multimedia utilities. If your computer was configured with Windows 95 before installing the AudioPCI, it is possible that these utilities are not installed.   To add the multimedia extensions: Click Start, Settings and Control Panel. The Control Panel screen appears. Place your Windows 95 CD in your CD-ROM drive. Double-click the Add/Remove Programs icon. The Add/Remove Programs Properties screen appears. Click the Windows Setup tab to access the page and bring it to the front. Click on the Multimedia checkbox to select the Multimedia components. You may have to scroll down the list of options. Click OK. If the Windows 95 System CD is needed, a prompt appears asking for it.
