WD1002A-WX1 User Guide Getting Started: Installation of the WD1002A-WX1 requires four steps: 1) Confirming BIOS ROM type; 2) Checking or setting jumpers; 3) installing into host computer; 4) formatting the disk drives. To complete installation, you will need the following: Two cables (3 if using two drives); MFM type drive; screwdriver; MSDOS Version 2.0 or later; *DEBUG utility; *FDISK utility; *FORMAT Utility. (*normally included with MSDOS); WARNING HANDLE THE CONTROLLER BY THE ENDS OF THE BOARD SOME OF THE CHIPS ARE STATIC SENSITIVE AND DAMAGE MAY OCCUR IF THE BOARD IS INCORRECTLY HANDLED Confirming BIOS At location U12, please confirm that your WD1002A-WX1 BIOS ROM is part number 62-000094-followed by any three numbers (this BIOS ROM is referred to as Western Digital's SUPERBIOS).

Verify that the jumper settings on the controller board are correct. Modification of factory jumper settings is rarely necessary. For jumper settings on W4, W6 and W8, refer to Table 1; Jumper settings for S1 are located on Table 2. CLOSED: Jumper (small shorting pens) is installed OPEN: Jumper is not installed. Table 1: * ≈ Sammy's settings Pin Jumper Connects Status W3 Closed * BIOS ROM Enabled Open BIOS ROM Disabled W4 2-3 * Device Address 320H 2-1 Device Address 324H W6 2-3 Reduced Write Curent (8 Heads) 2-1 * Head Sel 3 (16 heads) W8 2-3 * Standard factory setting. First or only disk controller in system. 1-2 Second disk controller in system. Requires modification of W4. The following S1 jumper settings are for standard 10/20 megabyte hard disk drives using default settings in the SUPERBIOS. If you are using a standard 10/20 megabyte drive, you may refer to the Simplified Formatting Instructions after completing the hardware installation procedures. If your drive is a non-standard drive (i.e. 20 megabyte drives with other than 4 heads/615 cylinders, or hard disk drives with a formatted capacity greater than 20 megabytes) you will need to refer to the Dynamic Formatting instructions after completing the hardware installation procedure. If you do not know your drive parameters, return to the STORAGE CONTROLLERS menu to access a listing of the most common drives and their parameters which we have provided for your convenience. If your drive is not listed, refer to your drive manual or contact the manufacturer.

WARNING MAKE SURE COMPUTER IS TURNED OFF AND POWER IS DISCONNECTED Installation of Controller into Host Computer Remove blank expansion slot bracket and save for future use. The screw will be used to hold the controller board into place. INSTALL CONTROLLER INTO ANY AVAILABLE SLOT EXCEPT SLOT 8 Connect the 34-pin (wide control cable) connector to J1 on the controller board. Make sure that Pin 1 of the cable connector goes to Pin 1 on the controller board. Pin 1 of the cable connector is typically located on the color coded side of the cable. Connect the 20-pin (data cable) to J2 (Drive 0 Data Connector) on the controller board. Make sure that Pin 1 on the cable is connected to Pin 1 on the controller board. If a second drive is being installed, connect the Drive 1 data cable to J3. Verify that the disk drive(s) is(are) installed properly. This includes correct placement of drive select jumpers and drive terminator installation. Refer to the disk drive installation manual for further information. DO NOT USE THE RADIAL SELECT OPTION. Install the drive(s) per manufacturer's instructions. CAUTION WHEN ROUTING 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.
