WESTERN WD93028/38/48-X/WD95028/38/48-X INSTALLATION GUIDE 79-000-35

Jumper Setting

==============

Jumper Option

-------------

The following option can be selected on the 6-pin header J8. Pins 1,

3, and 5 are connected to the port pins on the 8052 microcomputer IC

while pins 2, 4, and 6 are tied to ground.

Disable Translation

-------------------

You drive may be configured for the translation mode or the non-

translation mode. The translation mode allows you to your Western

Digital drive with an older S#system BIOS and/or operating systems

which only support MFM drives with 17 sectors per track. The non-

translation mode accommodates an RLL drive with 27 sectors per track.

When pins 1 and 2 are shorted together, the translate option is

disabled. If pin 1 is open, the translate option is enabled, and the

drive can be used with any BIOS that has a drive table listing less

than total sectors than your Western Digital drive (less than 42,228

sectors for the two-head drive assembly; and 84,456 for the four-head

drive assembly). For example, a Western Digital drive in translation

mode may replace a drive which has 615 cylinders, four heads and 17

sectors.

Dual Drive Operation

--------------------

If you are installing two physical drives in your XT system, the

first drive must be selected at port address 320H. Its BIOS resides

at address C800H. Select the second drive at port address 324H. Its

BIOS resides at CA00H. Both drives must therefore have seperate

cables connectinmg them to the motherboard. You will require Western

Digital\'s XT140 adapter card which has two 40-pin connectors. Plug

drive 0 into J1 connector and Drive 1 into J2 connector on the

adapter card.

Notes on installation

=====================

System Requirements

-------------------

You can use your drive in an IMB PC/XT or compatible system that has

these operating systems: MS-DOS version 2.0 and higher or Novell

NetWare. Contact your Western Digital dealer if you need informations

about other operating systems.

Gather Supplies

---------------

If your computer\'s motherboard has a 40-pin connector for installa-

tion of a hard disk drive, you will need the following items:

dir=\"ltr\"> |Capacity | 3.5 Inch | 5.25 Inch |

| | Form Factor | Frame |

| | | |

|20 MBytes | WD93028-X | WD95028-X |

|30 MBytes | WD93038-X | WD95038-X |

|40 MBytes | WD93048-W | WD95048-X |

dir=\"ltr\">

- Your Western Digital drive:

- One 40-pin interface cable (Maximum length of 18 inches)

- Optional mounting frame, bezel and LED

- IDE SUPERBIOS program for low-level formatting

If there is not a 40-pin connector on the motherboard or you intend

to place two hard disk drives in your system, your drive will

additionally require:

- Western Digital\'s XT140R adapter card with IDE SUPERBIOS or XT150R

adapter card with IDE SUPERBIOS and power connector.

- Additional 40-pin interface cable, if installing a second drive.

Mount the disk drive to the host using four 6-32 screws.

After securely mounting the drive, verify that nothing interferes

with the free movement of the drive\'s shock mounts.

WARNING

The only electrical ground contact should be from universal mounting

bracket to the frame on the host system. Do not ground to the hard

drive assembly (HDA) casting. Screws which are too long will cause a

ground loop to the HDA and defeat the shock mounting or possibly

damage board components. The screw should engage no more than six

threads (3/16 inch).

Connectors

----------

Interface Connector: 2 x 20 pin right angle .1\" Berg stick (pin 20

keyed)

Cable type: 40-conductor mass terminated flat ribbon

Cable length: 18 inches maximum

Product Description

-------------------

Western Digital\'s WD93028-X, WD93038-X, and WD93048-X are intelligent

drive products for the IBM PC/XT and compatibles. Their architectures

integrate an ST-412/ST-506 compatible hard drive assembly with a

controller on a single printed circuit board that is mounted on the

disk drive\'s chassis. The integration of disk drive and controller

increases reliability and performance by eliminating redundant

circuitry. Models WD93028-X, WD93038-X, and WD93048-X offer 20, 30,

and 40 MB of storage, respectively, in a 3.5 inch form factor. These

drives are also available in 5.25-inch frame (WD95028-X, WD95038-X,

and WD95048-X).

Formatting Your Drive

---------------------

Use the IDE SUPERBIOS program to perform a low-level format of your

drive. The WDXT140R or WDXT150R adapter card contains the IDE SUPER-

BIOS program. If you have an XT compatible with a drive interface

connector on the motherboard, it must provide a SUPERBIOS program. Do

no use the IBM Advanced Diagnostic Format Option.

The low-level format is performed just once for each physical drive.

When you dynamically configure a drive as two virtual drives

(partions), perform the low-level format only on drive C and the run

the DOS FDISK and FORMAT utilities on both logical drives (C and D).
