- WDXT-GEN2R
- HOW TO INSTALL YOUR SOFTWARE
-
- Now that you have installed the WDXT-GEN2R hardware, you need to install the
- software that tells your computer how to use the hardware.
-
- Software Installation Summary
-
- The software installation consists of the following three procedures:
-
-
- Low Level Format
-
- use pre-selected configuration (factory default drive table)
-
- use dynamic configuration (you type disk characteristics)
-
- Partition Hard Disk
-
- use DOS FDISK utility program
-
- High Level Format
-
- use DOS FORMAT utility program
-
-
- You may find it easier to install the WDXT-GEN2R software, if you first look
- over the complete set of instructions.
-
- Your software installation begins by using either the low level format with a
- pre-selected configuration or a low level format with a dynamic configuration.
-
- Use the low level format with a pre-selected configuration when you are
- installing a hard disk drive whose disk characteristics are the same as those
- in Table1-1.
-
- If you have a drive with parameters that are different from those in Table 1-1,
-
- then you will use the low level format with a dynamic configuration. The
- dynamic configuration is a process whereby you type the disk characteristics of
-
- your hard disk drive into the computer rather than using a drive table. If you
- use the dynamic configuration, you need to locate and enter values for the
- drive and to decide whether to do a virtual split.
-
- Your software installation ends by using the DOS utilities: FDISK and FORMAT.
-
- Where the instructions require you to shift between the text in this chapter
- and Appendix A, step numbers are kept consistent in both sections.
-
- If you are installing a drive with parameters that are different from the
- parameters in Table 1-1, skip the following section "Low Level Format (Pre-
- selected Configuration, 32 MB)" and instead go to Appendix C, "Dynamic
- Configuration."
-
-
-
-
-
-
-
-
-
-
-
-
-
- If you are installing a drive with parameters that are the same as the
- parameters in Table 1-1, use the low level format with a pre-selected
- configuration.
-
- CAUTION
-
-
- Do NOT start the low level format until you have a backup copy of the
- information on your hard disk. This warning usually applies to previously used
- hard disks.
-
- When you have a new hard disk, you usually do not have information to backup
- except in the case where your dealer installs some applications software on
- your unit.
-
- **************************************************************************
- LOW LEVEL FORMAT (Pre-selected Configuration, 32MB)
- **************************************************************************
-
- Before you start, turn your computer ON and make sure that a DOS diskette
- containing the Debug program is in drive A. Then proceed to the A> prompt.
-
- See your DOS manual if you need help getting to the A> prompt.
-
-
- 1. At the A> prompt,
-
- Type: DEBUG
-
- Press <Enter>
-
- 2. At the debug prompt (-),

- **************************************************************************
- FINAL STEPS
- **************************************************************************
-
- After you complete the low level format on your hard disk drive, you need to
- partition your drive and do a high level format before you can use your hard
- disk for the first time. The DOS programs: FDISK and FORMAT do this.
-
- FDISK and FORMAT are usually located on the supplemental DOS diskette.
-
- Partition Drive
-
- A partition divides the drive into units and prepares your hard disk for use
- with an operating system, such as MS-DOS.* You can select one partition which
- takes up your entire disk or several partitions, each occupying a portion of
- the disk. Each unit can have its own operating system.
-
- FDISK Utility
-
- If you just completed the low level format, the DOS diskette is in your
- computer and the A>> prompt is on your screen.
-
- To partition your hard disk with FDISK, follow the instructions below.
-
- 1. Make sure that the DOS diskette with FDISK is in drive A.
-
- 2. At the A> prompt,
-
- Type: FDISK
-
- Press <Enter>
-
- FDISK displays a series of menus. See your operating system manual for details
-
- on how to partition a hard disk. If in doubt, use the default values.
-
- Partition Second Disk Drive
-
- If you have two hard disk drives or created a virtual disk on your hard disk
- drive, then you must partition each drive.
-
- After you partition drive C, repeat the above steps. To partition drive D,
- select partition second hard disk.
-
- High Level Format
-
- As the final step to the software installation, you need to use the DOS FORMAT
- utility, which prepares the hard disk to accept MS-DOS files.
-
- The DOS utility program, FORMAT, will locate and deallocate media defects (bad
- tracks). Therefore if you did not mark the tracks bad during the low level
- format, this step does it for you automatically.
-
- FORMAT Switch "/S"
-
-
-
-
-
-
-
-
-
-
-
-
- FORMAT allows you to set certain "switches" which control various aspects of
- the procedure. The /s switch copies the operating system from the disk in the
- default drive (or the A drive) to the newly formatted disk.
-
- This is a simple way to get your operating system onto your hard disk.
-
-
- To use the FORMAT utility and load the operating system onto your newly
- installed hard disk drive, follow the steps below.
-
- 1. Make sure that the diskette with FORMAT is in drive A.
-
- 2. At the A> prompt
-
- Type: FORMAT C:/S
-
- Press <Enter>
-
- Follow the instructions on the screen to complete the process. See your
- operating system manual for details.
-
- At this point your hard disk is initialized and the system can read DOS from
- your hard disk, if you only have one partition.
-
- High Level Format Second Disk Drive
-
- If you partitioned your hard disk drive into more than one partition, you must
- format each logical drive.
-
- After you format drive C, repeat the above steps to format drive D, except for
- the following instructions:
-
- 2. At the A> prompt,
-
- Type: FORMAT D:
-
- Press <Enter>
-
- Follow the instructions on the screen to complete the process. See your
- operating system manual for details.
-
- You are now ready to go to the next chapter.

- HOW TO CHECK YOUR INSTALLATION
-
- After you completed the hardware installation, software installation, and use
- the FDISK and FORMAT C:/S utilities, you are ready to start using your system.
-
- Start System From Hard Disk
-
- You are ready to start your system using your newly installed hard disk drive
- and WDXT-GEN2R board.
-
- Remember: You must remove the diskette from drive A or else the system will
- start from drive A.
-
- To start the system
-
- 1. Simultaneously press the <Ctrl> <Alt> <Del> keys.
-
- 2. The system should respond, several screens may flash, and finally the C>
- prompt will appear.
-
- You may have to enter the date and time before the C> prompt appears. This
- depends on how your system is set.
-
- Installation Complete
-
- You are now done. The next time you can start your system from the hard disk.

-
- HOW TO HANDLE PROBLEMS
-
- If you had a problem with your system, first re-read the instructions to be
- sure that you followed them correctly. Check that you typed information EXACTLY
-
- as instructed.
-
- Repeat the procedure a second time to verify that you get the same error, then
- check the next section, "If You Have a Problem."
-
- If You Have a Problem
-
- First check your physical installation. Check for reversed cables, an
- overloaded system power supply, incorrect drive selection, etc.
-
- This section lists some common problems and possible solutions to try if you
- have problems when you install your controller.
-
- PROBLEM: No response.
-
- SOLUTION: Change cables. Do NOT use floppy cables.
-
- PROBLEM: Winchester activity LED always on.
-
- SOLUTION: Check cable connections. Try to reverse cables or replace cables.
- Check whether the drive has malfunctioned.
-
- PROBLEM: "Nothing done exit" appears when you start the low level format
- program.
-
- SOLUTION: You did not press the key. Restart low level format at step 1.
-
- PROBLEM: "Error Reading Fixed Disk" when booting the system.
-
- SOLUTION: DOS partition not active. See FDISK instructions in your DOS
- manual.
-
- PROBLEM: "Hard Disk Drive Not Ready" or "01" Error Code.
-
- SOLUTION: System BIOS ROM does not support Winchester (WDXT-GEN2R)
- controller and drive. Update system BIOS ROM. Overloaded power
- supply. Update system power supply.
-
- PROBLEM: Error code "80" while doing the low level format.
-
- SOLUTION: Drive select jumper on the hard disk drive unit is set
- incorrectly (see Chapter 1), or the cables are backwards, i.e.,
- Pins 1 & 34 switched or connector cables J2 & J3 switched. Also
- bad cables, no power to drive, or bad drive.
-
- PROBLEM: Error code "40" or "20" appears on screen.
-
-
-
-
-
-
-
-
-
-
-
-
- SOLUTION: Check cable connections. Try to reverse cables or replace
- cables. Also possibly the drive has malfunctioned.
-
- PROBLEM: After you do a high level format (Format C:/S), the message
- "Insert disk and press ENTER." appears. The system thinks drive C
- is a floppy disk drive.
-
- SOLUTION: Motherboard switches are set for the incorrect number of floppy
- disk drives. Check to see if RAM disk drivers are present.
-
- PROBLEM: "Bad Track 0" using DOS 3.1.
-
- SOLUTION: Make a config.sys file with BUFFERS=99. Reboot to load the
- configuration.
-
- PROBLEM: "Bad Track 0" using DOS 2.1. (DOS 2.1 cannot support bad tracks
- above 16.7 MB.)
-
- SOLUTION: Upgrade system to DOS 3.1 or LATER.
-
- PROBLEM: My 32MB hard disk drive has the same parameters as those in
- Table 1-1, which is 26 sectors per track. But when I looked at
- Table B-4, the default value shows 17 sectors per track. What's
- wrong?
-
- SOLUTION: Nothing. Notice that the default value in Table B-4 also selects
- sector translation. If your drive parameters are the same as those
- in Table 1-1, then you can use the factory default drive table and
- use the pre-selected configuration.
-
- PROBLEM: None of the suggestions seem to help.
-
- SOLUTION: Call your dealer.

-
- INSTALL A SECOND DRIVE ON AN EXISTING CONTROLLER
-
- This section tells you how to install a second fixed hard disk drive on an
- existing GEN2R controller board. You do not have to remove the existing GEN2R
- controller board, but you may have to remove the fixed hard disk so that you
- can remove the termination resistor. (This depends on the location of the fixed
-
- disk and the termination resistor.)
-
- Do not attempt to install your hardware unless you have compared your drive
- against the default drive parameters on page 1-2, and set the drive number and
- removed a termination resistor as explained starting on page 1-7.
-
- This installation requires you to remove the cover from your computer. See
- your computer manual for exact instructions on how to remove the cover.
-
- You need a 34-pin hard disk control cable in a daisy chain configuration and
- you also need a second 20-pin data cable.
-
- XT hardware limits you to two fixed hard disks. If you are installing a second
- drive on the GEN2R board, then the GEN2R board must be the only hard disk
- controller in your system.
-
- 1. Turn your computer power switch to OFF.
-
- 2. Use a screwdriver to loosen the cover screws. Then remove the computer
- cover, so that you can see the expansion slots.
-
- 3. Place the new hard disk drive unit into the computer case and attach per
- the manufacturer's installation instructions.
-
- 4. Look and see which expansion slot has the GEN2R board. You may have to lift
- the GEN2R board out of the slot to access the connectors.
-
- 5. Check if your existing 34-pin wide control cable is a daisy chain cable. A
- daisy chain cable has 3 connectors. If the cable is not a daisy chain
- cable, then remove the 34-pin wide control cable from the GEN2R board and
- the existing hard disk drive unit. You will replace this cable with a daisy
- chain cable in the next step.
-
- Leave the 20-pin cable attached to the board and the drive unit.
-
- 6. Connect cables to new hard disk drive unit. Follow steps A, B, and C.
-
- You may have to leave the drive case loose to connect the cables.
-
- Remember: Connect Pin 1 to Pin 1. Pin 1 of the cable connector is marked and is
-
- on the color coded edge of the cable. Pin 1 on the controller board is shown in
-
- Figure 1-1.
-
-
-
-
-
-
-
-
-
-
-
-
-
- A. (Omit this step if you are using an existing daisy chain cable)
- Connect the 34-pin (daisy chain wide control cable) end connector
- on the shorter length cable to the first hard disk drive unit's 34-pin
- connector.
-
- B. Connect the 34-pin middle connector on the shorter length daisy chain
- cable to the second hard disk drive unit's 34-pin connector.
-
- The longer length cable is unattached for now.
-
- C. Connect the second 20-pin data cable to the second hard disk drive unit's
- 20-pin connector.
-
- 7. Locate the internal 4-pin power connector(s) on your computer. See your
- computer manual. You need either two internal power connectors on your
- computer or you need to split the power connector.
-
- Connect the second drive unit to the second power connector plug.
-
- 8. Connect the free end of the 34-pin (wide control cable) connector to J1
- on the controller board. Attach Pin 1 of the cable connector to Pin 1
- on the controller board.
-
- Note: Pin 1 on the controller board is shown in Figure 1-1.
-
- 9. Connect the free end of the 20-pin data cable from the second drive to J3
- on the GEN2R controller board. Attach Pin 1 on the cable to Pin 1 on the
- controller board.
-
- 10. Place extra cable lengths so that they are out of the way.
-
- CAUTION
-
- Do NOT pinch the cables when you arrange them inside your computer case.
- Do not let the cables lay between the cover and an internal board. Do not
- obstruct air flow from fans or vents.
-
-
- 11. Replace the computer cover. Your hardware controller installation is
- complete. However, your GEN2R controller board is really a complex circuit
- composed of both hardware and software, so that while the hardware
- installation is complete, you still need to install the software. Proceed
- to Chapter 3 for the software installation steps.
-
- Tighten hard disk unit to computer case, if not already done so in step 3.
-
- **************************************************************************
- INTERLEAVE FACTORS
- **************************************************************************
-
- Interleave is a technique that allows the computer to read or write more
- thanone sector per track during a single disk rotation. Example: An interleave
-
- factor of 4:1 means that after the disk rotates 4 times, the computer has
- accessed all the information on a track.
-
-
-
-
-
-
-
-
-
-
-
- The interleave factor is system dependent. For WDXT-GEN2R boards and XT
- compatible computers an interleave factor of 4 is the default. You cannot have
- an interleave value less than 4 with the WDXT-GEN2R board.
-
- **************************************************************************
- VIRTUAL SPLIT
- **************************************************************************
-
- A virtual split is an "imaginary" dividing of the disk drive. When you do a
- virtual format, you make one physical drive appear as two or more disks to the
- system.
-
- DOS 2.0 allows a maximum of 16 megabytes per drive and DOS 2.1 permits 32
- megabytes per drive. Therefore a 40 megabyte drive must be virtually split in
- order to use all 40 megabytes.
-
- Only use the virtual split format when you have one physical hard disk in your
- system. If you have two physical hard disks, do not use the virtual split
- format.
-
- Select Virtual Split
-
- 6. To select the virtual configuration for your drive, answer the prompt,
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ │
- │ Are you virtually configuring the drive - answer Y/N │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
-
- Type: Y
-
- Press <<Enter>>
-
- The following prompt displays:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Key in cylinder number for virtual drive split as vvvv... │
- │ where:vvvv = number of cylinders for drive C: (1-4 digits) │
- └───────────────────────────────────────────────────────────────────────────┘
-
-
- Enter the value for your starting cylinder number,
-
- Follow the completed entry by pressing the <Enter> key.
-
- The number you entered represents the number of cylinders on drive C. The
- remaining cylinders are assigned to drive D during the virtual split process.
-
- The system displays the following prompt:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Press "y" to begin formatting drive C with interleave 04 │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
-
-
-
-
-
-
-
-
-
-
-
- Type: Y
-
- Press <Enter>
-
- 7. When the prompt for bad tracks displays, see the section on bad tracks.
- When the format is complete, the following message displays:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Format Successful │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
- Do not use the low level format program on the second "virtual" drive. The
- virtual drive is formatted when you select the virtual format option. Go to
- section, "Final Steps," in Chapter 3.
-
- **************************************************************************
- BAD TRACKS
- **************************************************************************
-
- Because a hard disk is a physically manufactured item, it sometimes has
- physical defects. Each drive manufacturer tests their drives and gives you a
- bad track media list, when you purchase the drive. This bad track list is
- usually located on the top of the disk drive case. Locate this list before you
- answer the prompts.
-
- 7. During the format program, you are asked if you want to map the bad tracks
- by the following prompt:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Do you want to format bad tracks - answer Y/N │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
- Because of the logical addressing used by DOS, marking an entire track bad
- results in more than one logical address being marked as bad. Since DOS limits
- the number of defects that it accepts, a drive with excessive media defects can
-
- cause the FORMAT program to terminate with an error, "TRACK 00 BAD - DRIVE
- UNUSABLE."
-
- Alternately, you can use the DOS utility program, FORMAT, to locate and
- deallocate media defects. Therefore we recommend that you do not mark the
- tracks bad; but if you decide that you want to mark the bad tracks, follow the
- steps below.
-
- Select Map Bad Tracks
-
- To map the bad tracks,
-
- Type: Y
-
- The system displays the following prompt:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Key in bad track list as follows: ccc h... │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
-
-
-
-
-
-
-
-
-
-
- where:
-
- ccc=bad track cylinder number
- h=bad track head number
-
- Enter each value separated by a space and follow the completed entry by
- pressing the <<Enter>> key.
-
- EXAMPLE: For a disk with a bad cylinder 160 on head 1 and bad cylinder 161 on
- head 3
-
- Type: 160 1 161 3
- Press <Enter>
-
- The bad tracks program displays the following prompt:
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ More? Y/N │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
- Enter additional bad tracks.
-
- To terminate the bad tracks program,
-
- Type: N
-
- Press <Enter>
-
- Then the following displays:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ BAD TRACK MAP │
- │ │
- │ TRACK ADDR PROBLEM │
- │ │
- │ cccH USER-SUPPLIED │
- └───────────────────────────────────────────────────────────────────────────┘
- When the format is completed, the message displays:
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Format Successful │
- │ │
- └───────────────────────────────────────────────────────────────────────────┘
-
-
- Now go to section "Final Steps" in Chapter 3, to partition your drive and do a
- high level format.
-
- **************************************************************************
- BIOS ROM Incompatibility
- **************************************************************************
-
- The following is a list of XT compatible computers which do not operate with
- the Western Digital BIOS ROM because of a system BIOS incompatibility.

- How To Change Jumpers
-
- To change a jumper, you need to solder electrical connections.
-
- CAUTION
-
- Do not attempt to change the jumper resistors unless you know how to
- solder electrical connections. Contact your dealer for advice on soldering
-
- jumper resistors.
-
-
- Note that the factory default settings have the jumper resistors out (i.e., not
-
- installed), except for R25, which is installed. R25 selects 17 sectors per
- track, sector translation, and prevents dynamic configuration.
-
- To add a jumper, you can solder 24 gauge wire to the pin positions that you
- want to connect.
-
- To remove a jumper that has been soldered into place, you can use a soldering
- iron to remove the connection.

- DYNAMIC CONFIGURATION
-
- Do not attempt to start the dynamic configuration unless you have set the
- jumper resistors, R25 out (i.e, not installed) and R26 in (i.e., installed).
- See Appendix B for more information on jumper resistors.
-
- The dynamic configuration allows you to enter the disk drive parameters
- yourself.
-
- CAUTION
-
- Do NOT start the low level format until you have a backup copy of the
- information on your hard disk. This warning usually applies to previously
- used hard disks.
-
-
- When you have a new hard disk, you usually do not have information to backup
- except in the case where your dealer installs some applications software on
- your unit.
