- PRELIMINARY STEPS
-
- This section describes steps you must take before installing the WD1007V
- controller in your system.
-
- GATHER SUPPLIES
-
- Make sure you have all the necessary equipment and software for installation of
- the WD1007V controller and configuration of your drive(s).
-
- screwdriver
-
- WD1007V-SE1 (Hard drive only controller) or WD1007V-SE2
- (Hard drive and floppy controller)
-
- One 34-pin control cable (daisy-chained, if installing two
- hard drives)
-
- One 20-pin data cable (two cables, if you are installing
- two hard drives)
-
- One 34-pin floppy cable (daisy-chained, if you are installing
- two floppy drives)
-
- IBM PC-AT or compatible system with a maximum of two ESDI hard drives or a
- maximum of two ESDI hard drives and two floppy drives
-
- MS-DOS version 3.3, Xenix, NetWare or other operating systems that provide disk
- partitioning
-
- Western Digital's WDFMT 2.10 for low-level formatting, if you do not have the
- optional WD1007V BIOS ROM
-
- **************************************************************************
- BASIC INPUT/OUTPUT SYSTEM (BIOS)
- **************************************************************************
-
- Determine if your system BIOS provides the appropriate drive tables for
- integration of your ESDI drive into your AT system. If it does not, you require
- the optional WD1007V BIOS. In order to properly install your ESDI drive, your
- system must have drive tables whose parameters match those of your drive. The
- drive tables specify the number of cylinders, heads, and sectors per track
- (SPT). It is often difficult to match the drive and the drive table exactly.
- When integrating an ESDI hard disk drive into your system, the number of
- sectors per track is the most important parameter to match. Most system BIOS
- ROMS support only the older MFM/ST506 drives that have 17 sectors per track.
- The ESDI disk drive typically has 34 or more sectors per track.
-
- In terms of maximum flexibility and adaptability with different drives, Western
- Digital recommends that you use the WD1007V BIOS. ESDI drives have the ability
- to present actual drive characteristics to the controller. The optional WD1007V
-
- BIOS ROM reads the ESDI information and generates the appropriate drive table.
-
-
-
-
-
-
-
-
-
-
-
-
- If you are installing a hard drive in your system and you wish to determine if
- your system's BIOS is adequate for configuration of your drive, use one of the
- following two methods to examine your system's BIOS:
-
- 1. Use your system's set-up program
-
- 2. Use the debug utility to examine the AT BIOS
-
- Note
-
- If your system is not operational or this is an initial setup of your
- system's hardware, then you will not be able to use these methods to
- examine your system BIOS. If you are unable to determine whether your
- system BIOS is adequate, then you need the WD1007V with the optional BIOS
- ROM.
-
-
- Using your system's setup program
-
- To determine if a system BIOS has the physical drive parameters required for
- your ESDI drive, refer to the appropriate manual for information about your
- setup utility, i.e., MS-DOS Users Guide, Advanced Diagnostics Guide, system
- BIOS guide, or user guide for other operating system. This utility can provide
- you with information about the drive types your system supports. If your drive
- tables do not support more than 17 sectors per track, we recommend that you use
- the optional WD1007V BIOS. The WD1007V BIOS provides translation schemes to
- fully utilize the capacity of your drive.
-
- Using the DOS Debug Utility to examine the AT BIOS
-
- Use the DOS Debug Utility to examine the system parameter tables to see if the
- drive is listed in the AT BIOS.
-
- 1. Place your DOS system diskette in Drive A and boot your system.
-
- 2. At the prompt (A:\>) type:
-
- debug and press the ENTER key
-
- Although some systems locate drive parameters in other locations, the standard
- location in the AT BIOS is F000:E401. The proper command at the Debug prompt
- (-) is as follows:
-
- df000:E401 and press the ENTER key
-
- This corresponds to drive types 1 through 8 and will display eight lines of
- data from the BIOS ROM. By entering another "d" at the debug prompt, another
- eight lines of data will be displayed, corresponding to drive types 9 through
- 16. Continue this procedure until all drive parameter information for all drive
- types is displayed. If your drive's parameters are encountered in this process,
- the system BIOS recognizes your particular drive.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Each parameter table has 16 bytes of data. Data from the BIOS ROM is displayed
- in hexadecimal, least significant byte first. This data breaks down as follows:
-
-
- Bytes 1 and 2 Number of Cylinders
- Byte 3 Number of Heads
- Bytes 4 & 5 Not Used
- Bytes 6 & 7 Write Precompensation Cylinder
-
- Byte 8 Not Used
- Byte 9 Control Byte (=08H for 8 heads)
-
- Byte 10-12 Not Used
- Bytes 13 & 14 Landing Zone 3
- Byte 15 Sectors per Track
- Byte 16 Not Used
-
- **************************************************************************
- IDENTIFY BOARD
- **************************************************************************
-
- You have the following controller board choices:
-
- Install the 1007V-SE1:
- If you are installing a hard drive and your floppy controller
- is on the motherboard or you currently have a separate floppy controller.
-
- Install the 1007V-SE2:
- If you are installing a hard drive(s) and a floppy drive(s)
- for the first time (there is no floppy controller on the motherboard)
- or you wish to replace your current controller(s). You must remove
- or disable any other controller in your system.
-
-
- **************************************************************************
- IDENTIFY DRIVE
- **************************************************************************
-
- The 1007V-SE1/SE2 controller supports two ESDI drives each having sixteen heads
- and 2048 cylinders.
-
- The 1007V-SE2 additionally supports two floppy disk drives (5.25 inch or 3.5
- inch with single density, double density, and high density formats).
-
- **************************************************************************
- UNPACKING THE CONTROLLER BOARD
- **************************************************************************
-
- CAUTION
-
- Hold the controller board by the ends. Static electrical discharge can
- permanently damage components if the board is not carefully handled.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Remove the controller board from its antistatic pouch and inspect it for any
- visible signs of damage (scratches, loose components, broken connectors).
- Contact your Western Digital sales representative if there is damage.
-
- Retain any packing materials for reuse if it becomes necessary to return your
- controller.

- HOW TO CONFIGURE AND INSTALL YOUR HARDWARE
-
- **************************************************************************
- HARD DISK DRIVE CONFIGURATION
- **************************************************************************
-
- Your hard disk drive has jumpers, switches or termination resistors that must
- be configured before you install the drive in your computer system. Before
- proceeding with the installation of your controller card, make certain your
- drive(s) is properly configured and physically installed according to the
- manufacturer's instructions.
-
- Verify proper termination of the last hard disk drive. The last drive
- (and only the last drive) in your system requires a termination resistor.
-
- Verify proper setting of drive select switches on your hard drive, if
- necessary. Your hard drive must be configured to support the hard sector
- mode.

- FIGURE 2-1. WD1007V-SE2
-
- Before you install the WD1007V, verify that the controller's jumpers (small
- shorting plugs) are properly set to reflect your configuration choices.
- Modification of the standard factory settings on the controller is rarely
- necessary. Modify the jumpers only under the direction of a qualified
- individual, i.e., your dealer. Figure 2-1 illustrates the jumper locations on
- the WD1007V-SE2 controller board. Figures 2-2 and 2-3 illustrate the jumper
- default settings for the WD1007V-SE2. Note that if you have the WD1007V-SE1
- version (hard disk only), jumpers W5 and W6 are not used.
-
-
-
-
-
-
-
-
-
-
-
-
-
- W1 Jumper Connections
-
- Module jumper W1 selects the firmware options illustrated in Figure 2-2 when no
-
- jumpers are installed. If you are merely replacing a WD1007A controller with a
- WD1007V controller and you do not wish to reformat your currently installed
- drive(s), you may elect to emulate the 1007A mode by installing jumpers on W1 9-
- 10 and W1 11-12.
-
- W1 1-2: When a jumper is installed, no cacheing occurs.
-
- When no jumper is installed, cacheing is enabled. Cacheing increases overall
- system performance by reading ahead and buffering data sectors likely to be
- requested by the host on subsequent read commands.
-
- W1 3-4: When a jumper is installed, the host receives seven bytes of error
- correction code (ECC) during Read Long and Write Long operations.
-
- When no jumper is installed, four byte ECC mode is selected. When using four
- byte ECC mode, three ECC bytes are temporarily saved until the next command or
- data transfer occurs.
-
- W1 5-6: When a jumper is installed, no disk address translation occurs. The
- controller assumes that logical values indicated by the Set Parameters command
- are the true physical values of the drive.
-
- Without a jumper, logical-to-physical translation occurs. The generic
- translation algorithm adapts any logical format to the physical format of the
- drive. However, the maximum logical parameters for INT 13 are 63 SPT, 16 heads
- and 1024 cylinders. See "Translation" in the Appendix for further explanation.
-
- W1 7-8: This is reserved for future use. No jumper is installed.
-
- W1 9-10: When a jumper is installed, it forces the drive to 35 SPT by issuing a
-
- Set Unformatted Bytes per Sector command to the drive. This overrides the
- drive's switches which select the SPT value. This jumper has no effect on
- drives having data transfer rates of 15 Mbits per second.
-
- Without a jumper, the controller uses the physical SPT value presented by the
- drive ( as determined by the drive's jumper settings).
-
- W1 11-12: When a jumper is installed, an alternate sector per track is
- provided. The alternate sector is useful when deallocating media defects.
- Mapping out media defects is important if you have an operating system which
- can accommodate only a certain number of errors. If you choose to format an
- alternate SPT for deallocation of media defects, you will not have access to
- the full capacity of your drive. This feature is explained further in the
- Appendix.
-
- W3 Jumper Connection.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- The 1007V BIOS resides at the absolute address of CC000-CFFFF or, if you are
- using "segment:offset" addressing, it resides at CC00:0000 to CC00:3FFF
- (CF00:0FFF). The overlay RAM occupies 256 bytes of the BIOS address range and
- is enabled following any memory write access to the address range. To disable
- the installed BIOS option, place a jumper on W3 1-2.
-
- W5 Jumper Connection.
-
- Without a jumper on W5 1-2, the WD1007V supports single-speed floppy drives.
- When jumpered, dual-speed floppy drives are supported.
-
- W6 and W12 Jumper Connection.
-
- To select the module's secondary address ranges, install jumpers on W6 1-2
- (floppy drives ) and W12 1-2 (fixed drives). The primary address ranges of 1F0-
- 1F7 and 3F2-3F7 are selected when jumpers are not installed.
-
- Primary Address Ranges Secondary Address Ranges
-
- Hard drives: 1F0-1F7 170-177
- Floppy drives: 3F2-3F7 372-377
-
- W9 Jumper Connection.
-
- Installing a jumper on W9 allows the user to ground the module's mounting
- bracket to board logic ground. This jumper is not normally installed.
-
- **************************************************************************
- INSTALLATION OF THE WD1007V
- **************************************************************************
-
- CAUTION
-
- To avoid electrical shock, make sure that all power to your computer is
- off and the power cord is disconnected from the electrical source.
-
-
- 1. Remove the power cord from the computer. If you remove any cables,
- note their location (for easy reassembly).
-
- 2. Remove the cover of the computer according to the instructions
- in your Owner's Manual.
-
- 3. Install your hard drive(s) and floppy drive(s) according
- to the manufacturer's instructions. Refer to your Owner's Manual for
- information about proper drive termination and select switches. Be
- certain there is a termination resistor on the last hard drive in
- your system.
-
- 4. Remove or disable any other controller in your system if
- you are installing the WD1007V-SE2. If you have a controller on your
- motherboard, disable it according to the manufacturer's instructions.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- 5. Select any 16-bit expansion slot and remove the blank expansion slot
- cover. It is best to locate the controller in the closest
- available expansion slot relative to the drive. Put the expansion
- slot cover away and save it for possible future use. Retain the screw
- to hold the controller board in place.
-
- 6. Connect the hard drive(s) to the controller board by following
- these steps:
-
- CAUTION
-
- When routing the cables, be careful not to pinch them. Cables must not
- get caught between the cover and the boards nor should they obstruct any
- air flow path from fans or vents.
-
- Do not confuse the hard drive's control cable with
- the cable for the floppy drives. They are not interchangeable.
-
-
- a. Connect the 34-pin control cable to J5 connector on the controller. Match
- the keyed connectors. Keyed connectors prevent accidental reversal of the
- cables which can cause severe damage to the drive and the controller.
-
- b. Connect the control cable to the hard disk drive(s). The daisy chain
- control cable has three connectors. If you have a second drive, plug the
- middle connector into the back of the second drive. The shorter length of
- the cable connects the drives: the longer length connects the drives to
- the controller card.
-
- c. Attach a 20-pin data cable to J4 connector on the controller.
-
-
- d. If you have a second hard disk drive, attach the second 20-pin data cable
- to J3 connector on the controller.
-
- e. Connect the data cable(s) to the hard disk drive(s). J4's cable connects
- to Drive 0: J3's cable connects to Drive 1.
-
- Note
-
- Your system will identify Drive 0 as Drive C: Subsequent drives or
- partitions are identified as D:, E:, F:, etc.
-
- 7. Connect the floppy drive(s) to the controller board by following these
- steps:
-
- a. Attach the 34-pin floppy cable to J1 connector.
-
- b. Connect the daisy-chain cable to the back(s) of the floppy drive(s). The
- daisy chain cable has three connectors. If you have a second drive, plug
- the middle connector into the back of the second drive. The shorter length
- of the cable connects the drives: the longer length connects the drives to
- the controller card.
-
-
-
-
-
-
-
-
-
-
-
-
-
- 8. Attach the Winchester activity LED connector to J6.
-
- 9. Carefully slide the controller board into the expansion slot. Ensure that
- the board is seated properly by pressing down evenly on both ends of the
- board. Secure the board with the expansion cover screw.
-
- 10. Replace computer cover.
-
- 11. Reattach all cables and power cords to the back panel of the system.
- The hardware installation is now complete. Follow the instructions
- for system setup.
-
- **************************************************************************
- INITIAL SETUP
- **************************************************************************
-
- Your setup utility performs numerous tasks that are essential to the definition
- of your system. Whether this is an initial setup or a change to your existing
- system, you need to run the setup utility to tell the system what types of
- hardware are installed.
-
- Follow the instructions in your operating system manual (MS-DOS or other
- operating system), system BIOS manual or whatever means your particular system
- uses to perform an initial setup. If later you experience problems with any
- hardware device, be sure to check your system setup. You may have incorrectly
- defined a device or not identified it at all.
-
