INTRODUCTION
****************************************************************************************************************
You probably ave an IBM* PS/2* personal computer and ave decided to upgrade it by adding a
larger ard disk drive and a WD1007V-MC1 board.
Or you may already ave a WD1007V-MC1 board in your system and you ave decided to add a
second ard disk drive. You can use your WD1007V-MC1 board to control a second ard disk,
provided t at t e WD1007V-MC1 board is t e only ard disk controller in your computer system.
C eck your system components and verify t at you do not ave anot er ard disk controller before
installing a second ard disk into your system.
Eac WD1007V-MC1 board can support two ard disk drives; owever, w en you install two
controllers into one computer, t e PS/2 system design limits you to a maximum of two fixed ard
disk drives.
T is document tells you ow you can install your WD1007V-MC1 board and ard disk drive and
t en start your system from t e ard disk.
Don't be worried. T is document will take you t roug t e process, step by step.

T e WD1007V-MC1 board is easy to install. T e following is a summary of t e installation steps,
w ic are completely explained in t is document.
1. Preliminary: identify drive, set drive configuration
2. Install ardware: drive, board, connect cables
3. Install software: use Reference Diskette, etc.
4. C eck installation: start system, use new board & drive
You do not need to disassemble your current ard disk drive nor remove t e ard disk controller.
Your ot er drive will still work after you ave installed your WD1007V-MC1 board and ard disk
drive unit.
CAUTION
Handle t e controller board by t e ends of t e board. Some of t e c ips are
static sensitive and damage may occur if t e board is incorrectly andled.
Exception, t e PS/2 system will NOT support two of t e same type controller. T erefore, if you
already ave an ESDI controller installed, you cannot install a second ESDI controller. If you are
replacing an existing controller, t en you need to remove t e old controller.

MICRO CHANNEL ARCHITECTURE
Since Micro C annel Arc itecture is new and different from XT and AT* arc itecture, t is section
explains some of its basic concepts and t e way in w ic t e Micro C annel arc itecture
implements computer programs.
W at is Micro C annel?
Micro C annel is a set of standards, w ic contain (among ot er items) ardware and firmware
standards t at define t e p ysical arrangement of personal computer perip eral devices, suc as
ard disk drives.
POS Register
T e POS (Programmable Option Select)register is a basic conceptual s ift from AT and XT
tec nology. In t ose systems, jumpers and DIP switc es told t e computer w at type of perip eral
ardware was attac ed. Wit Micro C annel arc itecture, no jumpers or DIP switc es are needed
on t e controller.
Instead t e system setup program along wit a system manufacturer supplied reference diskette
and t e POS registers tell t e computer w at is connected to t e system.
T e POS registers present to t e system a unique ID number for eac adapter installed. See
section ID# below.
CMOS Memory
Micro C annel computers use a CMOS (complementary metal-oxide semiconductor) memory c ip
and a battery back-up, so t at eac PS/2 computer can remember its own configuration, including
w ic board is in eac of its expansion slots.
ID#
Eac Micro C annel expansion board as a unique ID# coded into its firmware, w ic t e PS/2
compares wit its CMOS memory. T e ID# identifies eac Micro C annel board to files t at
contain its configuration information. T e ID# is automatically incorporated into t e computer's
setup software.
T erefore a Micro C annel computer knows w at type of board is located in eac expansion slot
and can detect w en a c ange is made to t e ardware and a different type board is placed in an
expansion slot. See section 165 Error.
Universal Expansion Installation
Since t e board ID# is in t e computer's setup software, one simple installation procedure can be
used for ANY expansion board, regardless of w at function it performs.

www.franken-online.de/ymmv 4/27

165 Error
If t e computer detects a c ange wit t e previous ID#, a 165 Error occurs. T e 165 Error
indicates t at t e system configuration as been c anged.
To correct Error 165, use t e Reference Diskette. See C apter 4 or your manufacturer's Micro
C annel ardware manual for instructions.
T e 165 Error does not occur w en you place t e Western Digital controller into t e same
expansion slot as t e one t at t e IBM controller occupied previously.
Besides t e 165 Error, ot er errors are possible w en you place a different board in an expansion
slot.
Two beeps indicate t at t e error is related to and can be corrected by t e IBM Reference
Diskette. Among t e more frequent errors t at occur are t e following: 162, clock; and 163,
calendar.
****************************************************************************************************************
DRIVE STANDARDS
****************************************************************************************************************
T e ESDI standard defines t e interface for ard disk drives connected to personal computers.
T e WD1007V-MC1 board works wit drives t at follow t e ESDI standards.
ESDI
T e ESDI interface defines a drive interface t at contains a set of standards t at include a relative
location for t e defect map in a prescribed format.
Block Address
An ESDI controller (WD1007V-MC1) interface does not define t e ard disk drive in t e same way
an ST506 interface (WD1006V-MC1). Rat er t an using ST506 type cylinder information, an ESDI
controller uses relative block addresses. T erefore ard disk drives controlled by an ESDI
controller board (WD1007V-MC1) don't need drive tables.
By eliminating t e drive tables and essentially iding t e p ysical c aracteristics of t e ESDI drive
from t e operating system, t e relative block address sc eme provides greater flexibility w en
configuring an ESDI drive and permits a computer wit a Western Digital ESDI controller to be
compatible wit most ESDI drives.
ESDI Defect Management
T e ESDI specifications define a standard ESDI defect map and locates t is map at t e maximum
cylinder. T e specifications also define a standard format for t is map. T e format and location are
bot a part of t e standard ESDI drive interface.
www.franken-online.de/ymmv 5/27

Standard ESDI Interface
Western Digital uses t e standard ESDI interface, but IBM does not define t eir drives according to
standard ESDI specifications. T erefore you can't use t e IBM Reference Diskette to format an
IBM drive wit a Western Digital controller. However, you can use t e IBM Reference Diskette, if
you ave a Western Digital controller board.
But since you can't use t e IBM Reference Diskette to format non-IBM drives wit t e IBM
controller; you also need to use t e Western Digital controller.
T us, you can use t e IBM Reference Diskette w en you are using a WD1007V-MC1 controller
board wit a non-IBM manufactured ESDI disk drive.

SOME PRELIMINARY STEPS
Before you begin t e actual installation of t e ardware and software, t ere are some preliminary
steps t at you need to do.
****************************************************************************************************************
GATHER SUPPLIES
****************************************************************************************************************
T e installation requires t at you gat er some tools and supplies before you begin. You'll need t e
following items:
● screwdriver
● PS/2 or Micro C annel compatible computer
○ space to old t e internal drive
● ard disk drive(s)
○ wit ESDI interface
○ See next section," System Limitations."
● interface cables ( ard 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 ot er operating system
● IBM Reference Diskette or ot er configuration diskette
● installation manual for PS/2 compatible computer
● installation manual for ard disk drive
****************************************************************************************************************
SYSTEM LIMITATIONS
****************************************************************************************************************
Eac WD1007V-MC1 board can support two ard disk drives; owever, w en you install two
controllers into one computer, t e PS/2 system design limits you to a maximum of two fixed ard
disk drives.
T us you can ave EITHER one WD1007V-MC1 board wit two ard disks attac ed to t e
WD1007V-MC1 board OR one WD1007V-MC1 board and one non-ESDI controller wit only one
ard disk attac ed to eac board.

www.franken-online.de/ymmv 7/27

****************************************************************************************************************
YOU CANNOT HAVE TWO WD1007V-MC1 BOARDS EACH HAVING TWO HARD DISKS
ATTACHED IN A PS/2 SYSTEM.
****************************************************************************************************************
Dual Controllers
Mix Controller Types: Alt oug t e PS/2 system will support two fixed disk controllers, it will NOT
support two controllers wit t e same type interface. T erefore, if you already ave an ESDI
controller installed, your new controller cannot ave t e ESDI interface.
ESDI Always Drive C
If you ave one ESDI and one ST506 drive connected to your computer, t e Micro C annel
arc itecture ALWAYS selects t e ESDI drive as Drive C, regardless of t e order in w ic you
installed or identified t em.
****************************************************************************************************************
IDENTIFY BOARD
****************************************************************************************************************
T e WD1007V-MC1 works wit ESDI drives. Table 2-1 lists t e computers t at are compatible wit
t e WD1007V-MC1 board.
Locate your board in Table 2-1 and make sure t at your computer model is compatible wit 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 c eck wit dealer
Space limitations may prevent installing drive unit inside computer case.
Note: T e IBM Models 25 & 30 do not support Micro C annel and are t erefore incompatible wit
t e WD1007V-MC1 board; owever, you can use Western Digital's XT controllers in your
IBM Models 25 & 30.
www.franken-online.de/ymmv 8/27

****************************************************************************************************************
IDENTIFY DRIVE
****************************************************************************************************************
Since t e WD1007V-MC1 board is only compatible wit t e ESDI drive interface, BE SURE YOU
HAVE AN ESDI DRIVE!!!
Look in t e drive manufacturer's literature and c eck t at you ave an ESDI drive interface.
Contact t e drive vendor to verify current models and revision level capacity.
W en you configure t e system, your computer will identify t at you ave an ESDI controller
installed and tell you its slot location.
Do I Need To Configure Any Jumpers?
No jumpers are set on t e WD1007V-MC1 board because t e Micro C annel looks at t e
ardware installed and knows t e configuration of t e boards. Micro C annel can detect address
conflicts and move ardware to different addresses using software.
****************************************************************************************************************
SET HARD DISK DRIVE CONFIGURATION
****************************************************************************************************************
T is section "Set Hard Disk Drive Configuration" refers to procedures t at you do to your ard disk
drives and not to your WD1007V-MC1 controller. Since t e WD1007V-MC1 board works wit many
ard disk drives, you need to consult your drive manufacturer's manual for exact details.
You need to set t e configuration for your ard disk drive unit before you install t e unit into your
computer. You set your ard disk configuration by adjusting jumpers, switc es, or termination
resistors.
Drive Settings
T e two settings t at you c ange are:
● drive number
● drive termination resistor
T e exact number of settings t at you c ange depends on your disk drive and computer.

Non-twist Cable Twisted Cable
www.franken-online.de/ymmv 9/27

Control Cables
Setting t e drive number depends on t e type of cable t at you use to connect your drive to your
controller board. T e two types of cables are listed below.
● flat, non-twist (ribbon) cable
● flat, twisted (ribbon) cable
First identify w ic cable you are going to use. Figure 2-1 illustrates t e two types of cables. In t e
twisted ribbon cable several wires ave been cut and twisted to form new connections.
If you plan to use t e existing cable in your computer, you may ave to open t e computer case.
See your computer manufacturer's instructions.
Set Drive Number (Twisted Cable)
W en t e 34-pin control cable is a twisted cable, set (jumper) bot ard disk drives for drive select
2. If you ave only one ard disk drive, set your single ard disk drive for drive select 2.
See t e drive manufacturer's manual for detailed instructions on ow to set t e drive number.
W en you install your ardware as explained in C apter 3, and you ave only one ard disk drive,
t at single ard disk drive will be placed at t e end of t e daisy c ain cable. WAIT UNTIL
CHAPTER 3 TO ATTACH YOUR HARD DISK DRIVE TO THE CABLE.
Set Drive Number (Non-twist Cable)
W en t e 34-pin control cable as NO twisted section, set (jumper) one drive for drive select 1
(i.e., drive 0) and t e ot er drive for drive select 2 (i.e., drive 1).
W en you install your ardware as explained in C apter 3, t e drive set for drive select 1 (i.e.,
drive 0) will be placed at t e end of t e daisy c ain cable. WAIT UNTIL CHAPTER 3 TO ATTACH
YOUR HARD DISK DRIVE TO THE CABLE.
Mark t e drives, so t at you know w ic drive you set for drive select 1 and w ic drive you set for
drive select 2. If you ave only one drive, set your single drive for drive select 1 (i.e., drive 0).
W en you install your ardware as explained in C apter 3, place t e single ard disk drive unit at
t e end of t e daisy c ain cable.
See t e drive manufacturer's manual for instructions on ow to set t e drive number.
Note: A daisy c ain cable as t ree connectors. T e electrical signal in a daisy c ain configuration
moves from one connection to t e next in sequence.
Set Drive Termination Resistor
T e drive termination resistor must be present only on t e drive, w ic is t e last p ysical drive
installed in a daisy c ain configuration. If you ave two ard disk drives, remove t e termination
resistor from t e drive, w ic will be attac ed to t e middle connector. See Figure 2-2.
If you ave only one fixed ard disk drive, do not c ange t e termination resistor. Drives are set at
t e factory as t e first ard disk drive (i.e., to be t e only drive in t e system).
See t e drive manufacturer's manual for instructions on ow to remove t e termination resistor.
