- INTRODUCTION
- ********************************************************************
-
- The WD1007V-SE2 Winchester/Floppy Disk Controller interfaces two ESDI-
- compatible hard disk drives and two floppy disk drives (5.25 or 3.5 inch) to a
- PC-AT system processor. The WD1007V-SE1 is a hard drive only version of the
- controller. The WD1007V BIOS ROM provides parameter tables, low-level
- formatting, surface analysis and defect management routines to fully integrate
- ESDI drive capabilities into your system.
-
- This document describes installation of the WD1007V-SE1/SE2
- Winchester/Floppy Disk Controller in the IBM Personal Computer AT or
- compatible.
-
- The following is a summary of the steps you will take to configure
- and install your controller board for use with your hard disk drive(s)
- and floppy drive(s).
-
- 1. Gather together necessary equipment and software
-
- 2. Unpack and inspect controller board
-
- 3. Configure and install hardware
-
- 4. Run setup utilities

- 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) <MI>or<D> WD1007V-SE2
- (Hard drive and floppy controller)
-
- - One 34-pin control cable (daisy-chained, if connecting two
- hard drives)
-
- - One 20-pin data cable (two cables, if you are connecting
- two hard drives)
-
- - One 34-pin floppy cable (daisy-chained, if you are connecting
- two floppy drives)
-
- - IBM PC-AT or compatible system with a maximum of two ESDI
- hard drives <MI>or<D> a maximum of two ESDI hard drives and two ANSI
- standard floppy drives with a density sensor
-
- - MS-DOS version 3.3 or higher, Xenix, NetWare or other operating
- systems that provide disk partitioning
-
- - If you are disabling the WD1007V BIOS ROM, then you will
- also need Western Digital's WDFMT for the low-level formatting
-
- ********************************************************************
- BASIC INPUT/OUTPUT SYSTEM (BIOS)
- ********************************************************************
-
- Many 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. Therefore, your system's BIOS ROM may not be adequate to support your
- ESDI drive.
-
- In terms of maximum flexibility and adaptability with different drives, Western
- Digital recommends that you use the WD1007V BIOS ROM. ESDI drives have the
- ability to present actual drive characteristics to the controller. The 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 want to use your
- system's BIOS ROM to configure your drive, disable the WD1007V BIOS as
- described in section 2, and refer to Appendix B for low-level formatting
- information.
-
- ********************************************************************
- 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)<MI>. You must remove
- or disable any other controller in your system.
-
-
- ********************************************************************
- IDENTIFY DRIVE
- ********************************************************************
-
- The 1007V-SE1/SE2 controller supports two ESDI drives, each having no more than
- 53 sectors per track, 16 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).
-
- ********************************************************************
- IDENTIFY CABLES
- ********************************************************************
-
- If you are installing a new hard drive along with the WD1007V controller board,
- here are a few words about cables. Figure 1-1 shows both a twisted and a non-
- twisted daisy chain cable for hard drives. Be careful not to confuse the
- twisted hard disk cable with a floppy daisy chain cable. They are not
- interchangeable. Floppy daisy chain cables also have 34-pin connectors and are
- usually twisted. The only distinguishing mark may be that the floppy cable has
- the twist located closer to pin 1 position. Also note that the twisted portion
- of the hard drive cable must have exactly five wires.
-
- If you only have one hard drive in your system, then you will probably use a
- standard two-connector, 34-pin cable (not shown).
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Note that the cable or cable connectors have been "keyed" in some fashion, such
- as a colored stripe on the cable identifying pin 1 position and/or a notch on
- the connector. This is to ensure proper connection of the cables to the
- drive(s) and controller card.

- 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 dealer 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, and/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. See Figure 2-1.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Figure 2-1 shows the proper drive selection settings and connections for your
- hard drive, depending upon whether you are using a twisted or non-twisted daisy
- chain cable. You may also have a standard two connector cable (not shown) for a
- single hard disk drive. If you have such a cable, set your drive select as "1"
- and do not remove the termination resistor.

- ********************************************************************
- FLOPPY DRIVE CONFIGURATION
- ********************************************************************
-
- Floppy drives are similarly selected and cabled. Be sure there is a termination
- resistor on the last floppy drive. Refer to your Owner's Manual for your floppy
- drive for proper selection and cabling information.
-
- ********************************************************************
- WD1007V JUMPER CONFIGURATION
- ********************************************************************
-
- 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 2-2 illustrates the jumper locations on
- the WD1007V-SE2 controller board. The WD1007V-SE1 board does not have jumpers
- W5 and W6. Please read the jumper descriptions which follow.

- FIGURE 2-2. WD1007V-SE2
-
- Note: The WD1007V-SE1 version of this controller does not support floppy drives
- and 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 must install 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. This is the most
- common selection. 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, the controller assumes that the values
- indicated by the Set Parameters command are the true physical values of the
- drive. Install this jumper only if your system supports the true physical
- parameters of your drive (number of heads, cylinders, SPT).
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- If you have a system which cannot support drives which have more than 17 SPT or
- drives that have more than 1024 cylinders, you require the default selection
- (no jumper). This provides a translation scheme to more fully utilize the
- capacity of your drive. See "Translation" in Appendix A for further
- explanation.
-
- W1 7-8: This is reserved. 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 lose some of your
- drive's storage capacity.
-
- This feature is explained further in Appendix A.
-
- W3 thru W12 Jumper Connections
-
- W3 Jumper Connection
-
- To disable the installed WD1007V BIOS ROM, place a jumper on W3 1-2. Use the
- system BIOS for low level formatting. See Appendix B.
-
- 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. Secondary address
- ranges are selected only when using a second controller or as a means of
- disabling a device.
-
- W7 Jumper Connection
-
- The 1007V-SE1/SE2 controller offers the default interrupt request, IRQ14.
- Jumper W7 1-2 is factory installed. Note that MS-DOS, OS/2, and most other
- operating systems work with IRQ14. Some operating systems may work with IRQ15
- if custom drivers are installed. If your particular application requires IRQ15,
- install the jumper on W7 2-3.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- W8 Jumper Connection
-
- W8 2-3 is jumpered to select the BIOS address range CC000 through CFFFF or, if
- expressed as a "segment:offset" address, CC00:0000 to CC00:3FFF (CF00:0FFF).
-
- By removing the jumper from W8 2-3 and placing it on jumper W8 1-2, the BIOS
- address range can be changed to C8000 through CBFFF or, if expressed as a
- segment:offset address, C800:0000 to C800:3FFF (CB00:0FFF). You only need to do
- this when there is a conflict between the BIOS address range and another
- device's address.
-
- ********************************************************************
- 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 and
- last floppy drive in your system. Be sure you use the right
- kind of cables for each device. (See Chapter 1, "Identifying Cables".
-
- 4. Remove or disable any other disk 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 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 a daisy chain cable for a hard drive with a floppy dasiy chain
- cable. They are not interchangeable.
-
- a. Connect the 34-pin control cable from the drive(s) to J5
- connector on the controller. (See Figure 2-6.) Match the keyed connectors.
- Keyed connectors prevent accidental reversal of the cables which can
- cause severe damage to the drive and the controller.
-
-
- 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.
-
-
- b. Attach the 20-pin data cable to J4 connector on the controller.
-
- c. If you have a second hard disk drive, attach the second
- 20-pin data cable to J3 connector on the controller.
-
-
- J4's cable connects to Drive 0: J3's cable connects to
- Drive 1.
-
- Note (DOS only)
-
- 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.
-
- A 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. If your system provides an activity LED indicator for the
- drive, plug it into J6 on the controller.
-
- 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.
-
- 12. Follow the instructions for system setup.
-
- ********************************************************************
- PERFORMING AN 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, system BIOS manual or
- use whatever means your particular system provides 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.
-
