If your motherboard does not support this feature truncate CMOS setting to 1024 cylinders. 2.0 Configuration ==================== 2.1 PCI Interrupt Selection ------------------------------ If you are using a Legacy card, then do not use PCI interrupts. The Legacy Header directly connects the IDE port interrupts to the proper ISA Interrupt. (Pri Port > IRQ14, Sec Port > IRQ15) There are four (4) shared PCI interrupts in a PCI system. They are PCI INTA, INTB, INTC, and INTD. When using the PCI interrupts, they must be routed the to an ISA interrupt for proper operation. This is usually done through the system CMOS Setup utility. All systems will differ slightly in their Setup utility. Within your Setup utility locate a section that refers to PCI, or you may find PCI selections under Advanced Chip Configuration. Here is an example of how to redirect interrupts. Slot 2 and INTA are used only for example. You may choose other options that are available. 1) Jumper Primary Port Interrupt as INTA 2) Place Card in PCI Slot 2 3) Power On system and enter Setup 4) Locate PCI configuration section 5) At this point each system may be very different. Refer to the follow examples to help determine how to setup your specific system: a) redirect PCI INTA to IRQ14 b) Set Slot 2 to IRQ14. c) Set Slot 2 to INTA and redirect INTA to IRQ14 6) Set Interrupt type to LEVEL trigger The selection of the Secondary Port Interrupt is based on the chip configuration. You may also have to redirect the secondary port interrupt, the same way as the primary port. NAT/LEG# LEG/INTx# Mode Interrupt W4 W3 1-2 X Shared on PCI INTx routed to ISA IRQ14 (where INTx is PCI INTA, INTB, INTC or INTD) 2-3 1-2 Pri Port >> ISA IRQ14, Sec Port >> ISA IRQ15 (either on MB, or card Legacy Header) 2-3 2-3 INTx >> IRQ15, IRQ12, or IRQ11 (IRQ15 is default, other IRQs can be selected through software switches) 2.2 Hardware Installation ---------------------------- Setup and Install your DTC IDE controller per the instructions provided in the Install Guide shipped with your specific card. 2.3 "EZIDE" Install Utility ------------------------------ DTC provides a utility to automatically install the Windows device driver into your Hard Disk Drive. This utility will copy all necessary files and update your SYSTEM.INI files. This utility requires that the C: drive has been Partitioned (DOS FDISK) and Formatted (DOS FORMAT). To use EZIDE, insert the DTC Enhanced IDE driver diskette in the A: drive and type: A:EZIDE <CR> Follow the on screen instructions. The EZIDE utility will walk you through the installation. 2.4 Software Device Drivers ------------------------------ The DTC Enhanced IDE Drivers will automatically configure the drives and the DTC IDE card for maximum performance/features. The DTC Enhanced IDE device drivers do automatic speed setting for each drive attached. You can combine drives with different speeds and multi-sector transfer capabilities on the same card. A set of Software switches have been included to: 1) Aid in debug 2) Work around HDDs that may not conform exactly to the ATA 3.0 and ATA-2 Specifications, or 3) Work around bugs that may exist in a HDD. Refer to Software Switches section for definition and use. 2.5 CMOS Settings -------------------- The System CMOS settings for Hard Disk Drive Types are for Hard Disk Drives attached to the PRIMARY PORT ONLY! 2.6 New IDE Hard Drive Installation -------------------------------------- If your new IDE HDD is NOT DOS Partitioned and DOS Formatted, then you will need to do so, refer to your DOS manual for instructions on the use of these utilities. The Enhanced Drive Parameter Table (EDPT) support is typically referred to as LBA or TRANSLATION mode in the system CMOS setup. Use the "/V" Verbose switch to determine what your system supports. (REF section 4.0) 2.7 Existing IDE Hard Drive Installation ------------------------------------------- If you are attaching an existing IDE Hard Drive (previously Partitioned and Formatted), then check the following: HDD Physical capacity < 528 MBytes * If the drive is Less Than 528 MBytes, then go to Section 3.1, and skip the DOS Partition and Format step. HDD Physical capacity > 528 MBytes * If the drive was formatted on a system that supported an Enhanced Drive Parameter Table (referred to as EDPT or LBA mode), then go to Section 3.1, and skip the DOS Partition and Format Step. * If the drive was Partitioned and Formatted using: 1) a proprietary Head mapping technique (referred to as Large/Big Drive or Head Mapping mode), or 2) a third party Software driver that breaks the 528 MByte barrier, then you will be required to Re-Partition and Re-Format the drive. !!! WARNING !!! Before Re-Partitioning or Re-Formatting the drive, make a backup copy (Floppy disk or other HDD) of all important data from the drive. All data will be erased from drive. * If the drive's total Partition capacity is less than the drive's Physical capacity, then you may want to Re-Partition and Re-Format the drive to the full capacity. !!! WARNING !!! Before Re-Partitioning or Re-Formatting the drive, make a backup copy (Floppy disk or other HDD) of all important data from the drive. All data will be erased from drive. 3.0 Installing Enhanced Device Drivers ========================================= 3.1 Windows 3.1x and Windows 95 ---------------------------------- All 32-bit DTC IDE controllers support 32-Bit Disk Access and 32-Bit file access under Windows 3.11. The DTC Windows driver, WIN4BM.386, is a Virtual Mode Driver (VxD) that can be used in place of WDCTRL. * IT IS RECOMMENDED TO FIRST VERIFY THAT YOUR SYSTEM AND HARD DRIVE IS * COMPATIBLE WITH THE 32-BIT DISK ACCESS FUNCTIONS UNDER WINDOWS USING * THE BUILT IN WDCTRL DRIVER. IF YOU HAVE BEEN SUCCESSFUL USING THE * WDCTRL DRIVER, THEN PROCEED WITH THE INSTALLATION OF THE DTC WINDOWS * DRIVER - WIN4BM.386 The WIN4BM.386 driver provides the same functions, but also includes Bus Master DMA transfers and 32-bit PIO transfers to the DTC IDE card, supports multi-sector transfers, and programs the DTC IDE card and each IDE device for optimal performance. * Copy the WIN4BM.386 file from the DTC Driver diskette into the C:\WINDOWS\SYSTEM directory. * Edit the file SYSTEM.INI located in the C:\WINDOWS directory. Locate the [386Enh] section. If "32BitDiskAccess" is already enabled (=on), you must disable the WDCTRL Driver by placing a semi-colon (;) at the beginning of the line. Then add the WIN4BM.386 driver line as follows: 32BitDiskAccess=on device=*int13 ;device=*wdctrl device=WIN4BM.386 If "32BitDiskAccess" is not enabled (=off), then add the following lines to the beginning of the [386Enh] section: 32BitDiskAccess=on device=*int13 device=WIN4BM.386 4.0 Software Switches ======================== The Software switches are NOT required for normal operation, but have been included to; 1) Aid in debug 2) Work around HDDs that may not conform exactly to the ATA 3.0 and ATA-2 Specifications, or 3) Work around bugs that may exist in a HDD. Refer to Software Switches section for definition and use. Software Switch Definitions --------------------------- The following section provides a description for each of the outlined software switches available for use with the appropriate software driver(s) mentioned in parenthesis. /v or /V Verbose Mode, Display Port and Drive Setup #1 Each Port configuration is displayed as follows: ### PCI CFG Mech #1; Native Mode; Port Base 0170H; DMA Base FDC0H; IRQ09; Each drive configuration is displayed as follows: >>> EDPT CHS: 0524, 32, 63; P4+IORDY; MWDMA1; M16; LBA; 32 Bit I/O; /irq:# or /IRQ:# Alternate Secondary Port Interrupt selection.

"EDPT CHS" if display, indicates that a Enhanced Drive Parameter Table is being used. This along with LBA support will allow installation of drives greater than 528 MBytes. "P#" is the IDE PIO Transfer Mode, refer above for details. "MWDMA#" is the Multi Word DMA Transfer Mode, refer above for details. "SWDMA#" is the Single Word DMA Transfer Mode, refer above for details. "M#" is the Multi-sector number. The number of sectors transferred per interrupt, refer above for details. "LBA" if displayed, indicates that the drive supports Logical Block Addressing. "IORDY" if displayed, indicates that the drive supports the "IORDY" signal, and IO Ready has been enabled. "32 Bit I/O" if displayed, indicates that PIO transfers are 32 bits wide. "16 Bit I/O" if displayed, indicates that PIO transfers are 16 bits wide. "IRQ14" indicates the ISA interrupt used for this drive. Examples; Using the Software switches ------------------------------------- The following examples will: disable multi-sector transfers and force PIO Mode 1 on the Primary Port Master drive. Set multi-sector transfers to 4 on the Primary Port Slave drive. Windows V3.10: (Enter in SYSTEM.INI file, [386Enh] section) WIN4BMSWITCH= /d0:m0 /d0:p0 /d1:m4 5.0 ATAPI Devices - IDE CDROM ================================ ATAPI is an acronym for ATA Packet Interface. ATAPI is a specification that defines a SCSI like command interface on the ATA (IDE) hardware register set (WD1003). The implementation of the ATAPI specification will allow device types other than Hard Disk Drives to work on ATA/IDE cards. The first device types available are CDROMs, but Tape devices are expected in the future. ISSUES: ------- 1) The ATAPI device will come with a ATAPI device driver. This device driver MUST be installed before you can access the ATAPI device. Follow the installation instructions provided with your ATAPI device. 2) Typically the ATAPI device driver will be installed in the CONFIG.SYS file. You should always load the ATAPI device driver AFTER any device driver that works with the Hard Disk Drives. 3) In Windows 3.1x or Windows for Work Groups, it is recommended that any ATAPI Devices, including IDE CDROMs be installed on a secondary IDE port. This will allow you to Enable the "32 Bit Disk Access" feature using either the WIN4BM.386 or WDCTRL.386 VxD drivers. One of the features of WDCTRL.386 and WIN4BM.386 is to support Virtual Memory. Virtual Memory is memory data that is stored on a Hard Disk Drive. This memory data is swapped between the physical memory and a Swap file on the drive as it is needed by applications. Because of this feature the VxD drivers will not allow access by other device drivers (ATAPI) to the IDE registers, for fear of corrupting the Virtual Memory data. 6.0 Q&A and Troubleshooting ============================== This section lists some of the problems the user might encounter following installation and configuration of a DTC IDE card. For additional troubleshooting information, refer to the Install Guide that you received with your DTC IDE card. It will contain information that may be specific or unique to your card. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% PROBLEM: When the DTC Enhanced IDE driver loads, you get an error message "Can Not Find COMMAND.COM", or the DTC card Hangs or Fails when you access the Hard Disk. SOLUTION: 1. Verify that the CMOS settings are correct for the drives attached. 2. Check that the drive has been Partitioned (FDISK) and DOS formatted. 3. Verify that you have properly redirected the Primary Port interrupt to IRQ14, and the Secondary Port interrupt to IRQ15 (IRQ12 or IRQ11 also supported on secondary only). 4. The information obtained from the drive about its operational capability, may be incorrect. Use the Software switches to put the drive in a standard operation mode. Step 1: Determine if DMA transfers are the problem by disabling DMA transfers. /dx:dd Step 2: Determine if Drive PIO Transfer rate is the problem by setting drive to standard PIO Mode 0. /dx:p0 Step 3: Determine if Multi-Sector is the problem by disabling Multi-Sector transfer. /dx:m0 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% PROBLEM: Unable to run Windows 3.1 or WFWG 3.11 in the Enhanced Mode. SOLUTION: The DTC IDE card DOES support WFWG 3.11 and Windows 3.1 in Enhanced mode. Check the following: 1. Verify that you have installed the latest DTC Windows Driver WIN4BM.386 in the SYSTEM.INI file correctly. See DTC Windows driver installation instructions. 2. If running in the Enhanced mode, any ATAPI Devices must be attached to the Secondary Port. 3. If you get a message indicating a Validation failure, write down the two numbers indicated and contact Microsoft or the drive's manufacture. This failure indicates that the drive/system is not compatible with Windows Enhanced mode. The most common failure is caused by setting the Cylinder # in the System CMOS to greater than 1024. Verify this by reducing the CMOS cylinder number to 1024 and then run windows. 4. Verify that the Windows supplied VxD Hard Disk Driver WDCTRL.386 functions without problems (REF section 3.2). If WDCTRL.386 does not work properly, neither will WIN4BM.386. This indicates that either the drive or the system has an incompatibility with Windows. 5. The IBM SLC microprocessor family causes a problem of this nature. Instead of using the WIN4BM.386 driver, use the WINDOWS built-in driver, WDCTRL.386. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% PROBLEM: Performance is not up to expectation. Data transfer rates appear slow. SOLUTION: 1) Use an IDE hard drive that supports multi-sector transfers and has a fast data transfer rate as reported by the drive manufacturer. New drives that support the ATA-2 Specification show the best results. 2) Bus Master DMA transfers will only work on HDDs that support IDE DMA transfers. New drives that support the ATA-2 Specification show the best results. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% QUESTION: What are the differences between IDE, EIDE and FAST ATA Hard Disk Drives? ANSWER: DTC has generated a white paper "Explanation of Enhanced IDE and FAST ATA". This paper can be obtained by calling the DTC Fax Back at (408) 942-4005, and request document # 529. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% QUESTION: How can I obtain the latest drivers for the DTC Enhanced IDE products? ANSWER: The latest release of DTC Enhanced IDE driver set is available from the DTC BBS. See the Technical Support section for details on the DTC BBS. You must Join the PCI conference. Download the file "IDEBMVxy.ZIP", where "xy" refers to the revision of the driver set (i.e "10" equates to 1.0A). The "IDEBMVxy.ZIP" file requires the utility PKUNZIP.EXE to release the individual drivers. If you do not have this utility, download "PKUNZIP.EXE" from the same conference. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% QUESTION: Can the DTC Enhanced IDE products support Hard Disk Drives with capacities greater than 528 MBytes? ANSWER: YES, The DTC Enhanced IDE drivers require that the Hard Disk Drive supports Logical Block Addressing (LBA) and the system CMOS supports an Enhanced Drive Parameter Table (EDPT). EDPT support may be referred to as the LBA option in the System CMOS Setup. You can use the "/V" software switch to determine your configuration (REF section 4.0 Software Switches). For installation and setup refer to sections 2.5 New IDE Hard Drive Installation and 2.6 Existing IDE Hard Drive Installation. 7.0 Drive Incompatibility List ================================= For the most up to date copy of the DTC "IDE Drive Compatibility List".
