- INTRODUCTION
- **************************************************************************
-
- You probably have an IBM* PS/2* personal computer and have decided to upgrade
- it by adding a larger hard disk drive and a WD1007V-MC1 board.
-
- Or you may already have a WD1007V-MC1 board in your system and you have decided
-
- to add a second hard disk drive. You can use your WD1007V-MC1 board to control
- a second hard disk, provided that the WD1007V-MC1 board is the only hard disk
- controller in your computer system. Check your system components and verify
- that you do not have another hard disk controller before installing a second
- hard disk into your system.
-
- Each WD1007V-MC1 board can support two hard disk drives; however, when you
- install two controllers into one computer, the PS/2 system design limits you to
-
- a maximum of two fixed hard disk drives.
-
- *IBM and PS/2 are registered trademarks of International Business Machines
- Corporation.
-
- This document tells you how you can install your WD1007V-MC1 board and hard
- disk drive and then start your system from the hard disk.
-
- Don't be worried. This document will take you through the process, step by
- step.
-
-
-
-
-
-
-
-
-
-
-
- The WD1007V-MC1 board is easy to install. The following is a summary of the
- installation steps, which are completely explained in this document.
-
- 1. Preliminary: identify drive, set drive configuration
-
- 2. Install hardware: drive, board, connect cables
-
- 3. Install software: use Reference Diskette,etc.
-
- 4. Check installation: start system, use new board & drive
-
- You do not need to disassemble your current hard disk drive nor remove the hard
-
- disk controller. Your other drive will still work after you have installed your
-
- WD1007V-MC1 board and hard disk drive unit.
-
- CAUTION
-
- Handle the controller board by the ends of the board. Some of the chips are
- static sensitive and damage may occur if the board is incorrectly handled.
-
- Exception, the PS/2 system will NOT support two of the same type controller.
- Therefore, if you already have an ESDI controller installed, you cannot install
-
- a second ESDI controller. If you are replacing an existing controller, then you
-
- need to remove the old controller.

- ABOUT THIS GUIDE
- **************************************************************************
-
- The following term is used in throughout this document.
-
- Reference Diskette - A generic term used to refer to the diskette supplied by a
-
- computer manufacturer, which contains the system configuration program. Used
- here the term is capitalized to refer to your manufacturer's diskette.
-
- Other Notations
-
- Angle brackets < > refer to a key. Therefore the symbol <Enter> refers to the
- Enter key.
-
- This may be marked differently on your keyboard, typically other notations are
- CR> for Carriage Return or RETURN or <Return> for the Return key.
-
- This guide was written using the IBM PS/2 computers as a model. Sometimes
- specific examples, such as errors, refer to the IBM error code numbers.
- Therefore if you have a PS/2 compatible computer, your error numbers
- may be different.
-
- For example on page 6-2, error codes 162, 163, 165, and 166 refer to the IBM
- error codes. These numbers may not be the same if you have a PS/2 Micro
- Channel* compatible computer.
-
-
-
-
-
-
-
-
-
-
- About Menu Screens:
-
- Because manufacturers are always updating their software, and this installation
-
- guide covers installing WD1007V-MC1 controller boards in many PS/2 compatible
- computers, as well as IBM PS/2 computers, the menu screens used here represent
- the best available information.
-
- Do not be concerned if your screens don't match those documented here. Always
- follow the manufacturer's instructions for their compatible computer (i.e. if
- you have an Apricot computer, use the Apricot Reference Diskette).

- MICRO CHANNEL ARCHITECTURE
-
- Since Micro Channel Architecture is new and different from XT and AT*
- architecture, this section explains some of its basic concepts and the way in
- which the Micro Channel architecture implements computer programs.
-
- What is Micro Channel??
-
- Micro Channel is a set of standards, which contain (among other items) hardware
-
- and firmware standards that define the physical arrangement of personal
- computer peripheral devices, such as hard disk drives.
-
- POS Register
-
- The POS (Programmable Option Select)register is a basic conceptual shift from
- AT and XT technology. In those systems, jumpers and DIP switches told the
- computer what type of peripheral hardware was attached. With Micro Channel
- architecture, no jumpers or DIP switches are needed on the controller.
-
- *AT is a registered trademark of International Business Machines Corporation.
-
- Instead the system setup program along with a system manufacturer supplied
- reference diskette and the POS registers tell the computer what is connected to
-
- the system.
-
- The POS registers present to the system a unique ID number for each adapter
- installed. See section ID# below.
-
- CMOS Memory
-
- Micro Channel computers use a CMOS(complementary metal-oxide semiconductor)
- memory chip and a battery back-up, so that each PS/2 computer can remember its
- own configuration, including which board is in each of its expansion slots.
-
- ID#
-
- Each Micro Channel expansion board has a unique ID# coded into its firmware,
- which the PS/2 compares with its CMOS memory. The ID# identifies each Micro
- Channel board to files that contain its configuration information. The ID# is
- automatically incorporated into the computer's setup software.
-
- Therefore a Micro Channel computer knows what type of board is located in each
- expansion slot and can detect when a change is made to the hardware and a
- different type board is placed in an expansion slot. See section 165 Error.
-
- Universal Expansion Installation
-
- Since the board ID# is in the computer's setup software, one simple
- installation procedure can be used for ANY expansion board, regardless of what
- function it performs.
-
-
-
-
-
-
-
-
-
-
-
-
-
- 165 Error
-
- If the computer detects a change with the previous ID#, a 165 Error occurs. The
-
- 165 Error indicates that the system configuration has been changed.
-
- To correct Error 165, use the Reference Diskette. See Chapter 4 or your
- manufacturer's Micro Channel hardware manual for instructions.
-
- The 165 Error does not occur when you place the Western Digital controller into
-
- the same expansion slot as the one that the IBM controller occupied previously.
-
- Besides the 165 Error, other errors are possible when you place a different
- board in an expansion slot.
-
- Two beeps indicate that the error is related to and can be corrected by the IBM
-
- Reference Diskette. Among the more frequent errors that occur are the
- following: 162, clock; and 163, calendar.
-
- **************************************************************************
- DRIVE STANDARDS
- **************************************************************************
-
- The ESDI standard defines the interface for hard disk drives connected to
- personal computers. The WD1007V-MC1 board works with drives that follow the
- ESDI standards.
-
- ESDI
-
- The ESDI interface defines a drive interface that contains a set of standards
- that include a relative location for the defect map in a prescribed format.
-
- Block Address
-
- An ESDI controller (WD1007V-MC1) interface does not define the hard disk drive
- in the same way an ST506 interface (WD1006V-MC1). Rather than using ST506 type
- cylinder information, an ESDI controller uses relative block addresses.
- Therefore hard disk drives controlled by an ESDI controller board (WD1007V-MC1)
-
- don't need drive tables.
-
- By eliminating the drive tables and essentially hiding the physical
- characteristics of the ESDI drive from the operating system, the relative block
-
- address scheme provides greater flexibility when configuring an ESDI drive and
- permits a computer with a Western Digital ESDI controller to be compatible
- with most ESDI drives.
-
- ESDI Defect Management
-
- The ESDI specifications define a standard ESDI defect map and locates this map
- at the maximum cylinder. The specifications also define a standard format for
- this map. The format and location are both a part of the standard ESDI drive
- interface.
-
-
-
-
-
-
-
-
-
-
- Standard ESDI Interface
-
- Western Digital uses the standard ESDI interface, but IBM does not define their
-
- drives according to standard ESDI specifications. Therefore you can't use the
- IBM Reference Diskette to format an IBM drive with a Western Digital
- controller. However, you can use the IBM Reference Diskette, if you have a
- Western Digital controller board.
-
- But since you can't use the IBM Reference Diskette to format non-IBM drives
- with the IBM controller; you also need to use the Western Digital controller.
-
- Thus, you can use the IBM Reference Diskette when you are using a WD1007V-MC1
- controller board with a non-IBM manufactured ESDI disk drive.

-
- SOME PRELIMINARY STEPS
-
- Before you begin the actual installation of the hardware and software, there
- are some preliminary steps that you need to do.
-
- GATHER SUPPLIES
-
- The installation requires that you gather some tools and supplies before you
- begin. You'll need the following items:
-
- screwdriver
-
- PS/2 or Micro Channel compatible computer
-
- space to hold the internal drive
-
- hard disk drive(s)
-
- with ESDI interface
-
- See next section," System Limitations."
-
- interface cables (hard disk cables <B>NOT floppy disk cables)
-
- 20-pin data cable (1 or 2)
-
- 34-pin control cable (for 1 or 2 drives)
-
- DOS version 3.3 or later or OS/2* or other operating system
-
- IBM Reference Diskette or other configuration diskette
-
- installation manual for PS/2 compatible computer
-
- installation manual for hard disk drive
-
- **************************************************************************
- SYSTEM LIMITATIONS
- **************************************************************************
-
- Each WD1007V-MC1 board can support two hard disk drives; however, when you
- install two controllers into one computer, the PS/2 system design limits you to
-
- a maximum of two fixed hard disk drives.
-
- Thus you can have EITHER one WD1007V-MC1 board with two hard disks attached to
- the WD1007V-MC1 board OR one WD1007V-MC1 board and one non-ESDI controller with
-
- only one hard disk attached to each board.
-
- * OS/2 is a trademark of International Business Machines Corporation.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- **************************************************************************
- YOU CANNOT HAVE TWO WD1007V-MC1 BOARDS EACH HAVING TWO HARD DISKS ATTACHED IN A
-
- PS/2 SYSTEM.
- **************************************************************************
-
- Dual Controllers
-
- Mix Controller Types: Although the PS/2 system will support two fixed disk
- controllers, it will NOT support two controllers with the same type interface.
- Therefore, if you already have an ESDI controller installed, your new
- controller cannot have the ESDI interface.
-
- ESDI Always Drive C
-
- If you have one ESDI and one ST506 drive connected to your computer, the Micro
- Channel architecture ALWAYS selects the ESDI drive as Drive C, regardless of
- the order in which you installed or identified them.
-
- **************************************************************************
- IDENTIFY BOARD
- **************************************************************************
-
- The WD1007V-MC1 works with ESDI drives. Table 2-1 lists the computers that are
- compatible with the WD1007V-MC1 board.
-
- Locate your board in Table 2-1 and make sure that your computer model is
- compatible with your controller board.
-
- TABLE 2.1 COMPUTERS COMPATIBLE WITH WD1007V-MC1
-
- COMPUTER
-
- IBM Model 50
-
- IBM Model 50z
-
- IBM Model 60
-
- IBM Model 70/16MHz
-
- IBM Model 70/20MHz
-
- IBM Model 80/16MHz
-
- IBM Model 80/20MHz
-
- Non-IBM computer check with dealer
-
- Space limitations may prevent installing drive unit inside computer case.
-
- Note: The IBM Models 25 & 30 do not support Micro Channel and are therefore
- incompatible with the WD1007V-MC1 board; however, you can use Western Digital's
-
- XT controllers in your IBM Models 25 & 30.
-
-
-
-
-
-
-
-
-
-
-
- **************************************************************************
- IDENTIFY DRIVE
- **************************************************************************
-
- Since the WD1007V-MC1 board is only compatible with the ESDI drive interface,
- BE SURE YOU HAVE AN ESDI DRIVE!!!
-
- Look in the drive manufacturer's literature and check that you have an ESDI
- drive interface. Contact the drive vendor to verify current models and revision
-
- level capacity.
-
- When you configure the system, your computer will identify that you have an
- ESDI controller installed and tell you its slot location.
-
- Do I Need To Configure Any Jumpers?
-
- No jumpers are set on the WD1007V-MC1 board because the Micro Channel looks at
- the hardware installed and knows the configuration of the boards. Micro Channel
-
- can detect address conflicts and move hardware to different addresses using
- software.
-
- **************************************************************************
- SET HARD DISK DRIVE CONFIGURATION
- **************************************************************************
-
- This section "Set Hard Disk Drive Configuration" refers to procedures that you
- do to your hard disk drives and not to your WD1007V-MC1 controller. Since the
- WD1007V-MC1 board works with many hard disk drives, you need to consult your
- drive manufacturer's manual for exact details.
-
- You need to set the configuration for your hard disk drive unit before you
- install the unit into your computer. You set your hard disk configuration by
- adjusting jumpers, switches, or termination resistors.
-
- Drive Settings
-
- The two settings that you change are:
-
- drive number
-
- drive termination resistor
-
- The exact number of settings that you change depends on your disk drive and
- computer.

- Non-twist Cable Twisted Cable
-
-
-
-
-
-
-
-
-
-
-
- Control Cables
-
- Setting the drive number depends on the type of cable that you use to connect
- your drive to your controller board. The two types of cables are listed below.
-
- flat, non-twist (ribbon) cable
-
- flat, twisted (ribbon) cable
-
- First identify which cable you are going to use. Figure 2-1 illustrates the two
-
- types of cables. In the twisted ribbon cable several wires have been cut and
- twisted to form new connections.
-
- If you plan to use the existing cable in your computer, you may have to open
- the computer case. See your computer manufacturer's instructions.
-
- Set Drive Number (Twisted Cable)
-
- When the 34-pin control cable is a twisted cable, set (jumper) both hard disk
- drives for drive select 2. If you have only one hard disk drive, set your
- single hard disk drive for drive select 2.
-
- See the drive manufacturer's manual for detailed instructions on how to set the
-
- drive number.
-
- When you install your hardware as explained in Chapter 3, and you have only one
-
- hard disk drive, that single hard disk drive will be placed at the end of the
- daisy chain cable. WAIT UNTIL CHAPTER 3 TO ATTACH YOUR HARD DISK DRIVE TO THE
- CABLE.
-
- Set Drive Number (Non-twist Cable)
-
- When the 34-pin control cable has NO twisted section, set (jumper) one drive
- for drive select 1 (i.e., drive 0) and the other drive for drive select 2
- (i.e., drive 1).
-
- When you install your hardware as explained in Chapter 3, the drive set for
- drive select 1 (i.e., drive 0) will be placed at the end of the daisy chain
- cable. WAIT UNTIL CHAPTER 3 TO ATTACH YOUR HARD DISK DRIVE TO THE CABLE.
-
- Mark the drives, so that you know which drive you set for drive select 1 and
- which drive you set for drive select 2. If you have only one drive, set your
- single drive for drive select 1 (i.e., drive 0). When you install your hardware
-
- as explained in Chapter 3, place the single hard disk drive unit at the end of
- the daisy chain cable.
-
- See the drive manufacturer's manual for instructions on how to set the drive
- number.
-
- Note: A daisy chain cable has three connectors. The electrical signal in a
- daisy chain configuration moves from one connection to the next in sequence.
-
-
-
-
-
-
-
-
-
-
-
- Set Drive Termination Resistor
-
- The drive termination resistor must be present only on the drive, which is the
- last physical drive installed in a daisy chain configuration. If you have two
- hard disk drives, remove the termination resistor from the drive, which will be
-
- attached to the middle connector. See Figure 2-2.
-
- If you have only one fixed hard disk drive, do not change the termination
- resistor. Drives are set at the factory as the first hard disk drive (i.e., to
- be the only drive in the system).
-
- See the drive manufacturer's manual for instructions on how to remove the
- termination resistor.

- HOW TO INSTALL YOUR HARDWARE
-
- This section tells you how to install the hardware portion of your WD1007V-MC1
- controller board. You can install the controller board in any available Micro
- Channel compatible expansion slot.
-
- Do not attempt to install your hardware unless you have set the hard disk drive
-
- configuration as explained starting on page 2-6.
-
- The installation requires you to remove the cover from your computer. See your
- PS/2 manual for exact instructions on how to remove the cover.
-
- If you are replacing an existing controller, then you also have to remove your
- old hard disk controller.
-
- CAUTION
-
- The IBM PS/2 system does NOT support two of the same type controller.
-
- Therefore, if you already have an ESDI controller installed, your new
-
- controller requires another type interface.
-
-
- If you want two of the same type of hard disk, daisy chain them onto one
- WD1007V-MC1 controller board.
-
- 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 and internal space to place the
- fixed disk drive unit.
-
- This is an IBM limitation. See IBM manual for more information.
-
- 3. Place your hard disk drive unit(s) into the computer case and attach to the
-
- case according to the manufacturer's installation instructions.
-
- 4. Look and see which expansion slots are empty. Select one that has the same
- type of connectors as those on the WD1007V-MC1 board.
-
- Or if you are removing a controller, locate the one which has the old
- controller in it. Use this expansion slot.(no 165 error)
-
- Note: You can also install a new fixed hard disk drive on an existing WD1007V-
- MC1 controller. See Appendix.
-
- You may have to leave the drive case loose to connect the cables. Look and
- determine whether to tighten the connections from the position of the cable
- connectors.
-
- 5A. If you are removing an old controller, loosen the plastic screw which
- holds the old controller board in place. Then slide the old board out of the
- expansion slot and remove the cables.
-
-
-
-
-
-
-
-
- 5B. If you are using a "new" expansion slot, loosen the plastic screw that
- holds the expansion slot cover you selected in step 4. The plastic screw is
- located at the rear. Slide the expansion slot cover up, and remove it.
-
- 6. Connect cables to hard disk drive unit. Follow steps A,B,C, and D. These
- instructions are for both one or two drives on the same controller.
-
- Cable connectors have an orientation. Pin 1 is not the same as Pin 34. Each
- carries a different electrical signal. Therefore your unit will not work
- properly, if you do not connect Pin 1 of the cable connector to Pin 1 on the
- drive.
-
- 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 3-2.

- FIGURE 3-1. DAISY CHAIN CABLE CONNECTORS
-
- A. (for 1 drive only) Connect the 34-pin (wide control cable) connector to the
- hard disk drive unit's 34-pin (card edge type) connector. Attach Pin 1 of the
- cable to Pin 1 on the hard disk drive connector.
-
- (for 2 drives only) If you are installing two hard disk drives on one
- controller, use a daisy chain cable. Connect the end connector on the shorter
- cable length to the first drive unit. See Figure 3-1 for daisy chain cable
- connections.
-
- The longer length cable is unattached for now.
-
- B. (for 2 drives only) Connect middle 34-pin connector on the shorter length
- daisy chain cable to the second hard disk drive unit's 34-pin connector.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Remember: The second hard disk drive is the unit from which you removed the
- termination resistor. See page 2-11.
-
- The longer length cable is unattached for now.
-
- C. Connect the 20-pin (data cable) to the first hard disk drive unit's 20-pin
- connector. Attach Pin 1 of the cable to Pin 1 on the hard disk drive.
-
- D. (for 2 drives only) Connect the second 20-pin (data cable) to the second
- hard disk drive unit's 20-pin connector.
-
- 7. Locate the internal four pin power connector(s) on your computer. See your
- computer manual. Connect this internal four pin power connector to your new
- fixed hard disk drive unit's power connector plug.
-
- (for 2 drives only) If you are installing 2 drives, you need either two
- internal power connectors on your computer or you need to split the power
- connector. See the manufacturer's manual.
-
- Connect the second drive unit to the second power connector plug.
-
- 8. Place the controller board into the expansion slot that you selected in step
-
- 4. Slide the edge of the board into the expansion slot at the rear of your
- computer and press firmly on the plastic edges of the board as you insert it
- into the expansion slot. You will feel the board slip into place and fit
- snugly. The WD1007V-MC1 edge connectors fit snugly into the slot. Check that
- the board is seated properly, it should NOT wobble freely.
-
- 9. After the board is seated firmly in the expansion slot socket, fasten the
- end of your board to the computer rear panel. Tighten the plastic screw (which
- you loosened in step 5) to the computer chassis.
-
-
- 10. Connect the free end of the 34-pin (wide control cable) connector to J4 on
- the WD1007V-MC1 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 3-2.
