- WD1006S-WAH
-
- User Guide
-
-
- The WD1006S-WAH controller is designed to interface with up to two
- Winchester ST506/ST412 hard disk drives in an IBM PC AT or compatible
- system and will support drives with up to 16 read/write heads and
- 2048 cylinders. Each drive may be a different configuration. The
- advanced design of the WD1006S-WAH implements the controllers most
- significant feature, 1:1 interleave.
-
- The WD1006S-WAH has the same integrated circuit set and operates
- identically as the WD1006-WAH. The primary difference between the
- two controllers is size. The WD1006S-WAH occupies a half slot in the
- host system because surface mount technology (SMT) reduced the
- physical dimensions to 6.10 inches x 3.90 inches. The WD1006-WAH
- occupies a full slot.
-
- There is only one version of the WD1006S-WAH available. Feature 001
- (F001) offers cacheing firmware, NO wait state generator.
-
- Installation of the controller requires three steps: 1) verifying
- jumper settings; 2) installing into the host computer; 3) formatting
- the hard disk drives. To complete installation, you will need the
- following:
-
- Two hard disk cables (3 if using 2 hard disk drives); Winchester hard
- disk drive; screwdriver; MSDOS Version 2.0 or later; IBM Advanced
- Diagnostic diskette (or similar program for IBM compatibles); FDISK
- and Format utility (normally included with MSDOS).

- Preparation of Controller
-
- 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
-
- Before you can install your WD1006S-WAH, you will need to be certain
- that the jumpers (small shorting plugs) are correctly set. Refer to
- Table 1 for correct jumper settings. Modification of factory jumper
- settings is rarely necessary. Modify jumpers only under the
- direction of a qualified individual; i.e. your dealer.

- Jumper Position Function
-
- W1 1-2 Standard: Etch on the solder side
- connects pins 1 and 2. Drive LED is not
- latched; i.e. LED lights for drive selec-
- tion. REMOVE W6 IF W1 IS INSTALLED.
-
- No Jumper Drive LED is latched.
-
- W2 1-2 Standard: Uses header connector. No etch
- between pins 1 and 2. Supports 16 heads. No
- REDUCED WRITE CURRENT (RWC).
-
- 2-3 Supports 8 heads and RWC.
-
- W3 No Jumper Standard: Enables cacheing.
-
- 1-2 Disables cacheing. Must install jumper
- to disable cacheing.
-
- W4 No Jumper Isolates mounting bracket from board logic
- ground.
-
- 1-2 Connects mounting bracket to board logic
- ground.
-
- W5 1-2 Standard: Selects primary ports. Etch on
- solder side connects pins 1 and 2.
-
- 2-3 Selects secondary ports. Requires cutting
- etch between pins 1 and 2 and installing
- a jumper. NOTE: MOST HOST SYSTEM BIOS
- DEVICE DRIVERS SUPPORT PRIMARY PORTS ONLY.

- Hardware Installation
-
- WARNING
- MAKE SURE COMPUTER IS TURNED OFF
- AND POWER IS DISCONNECTED
-
- 1. Verify that your host computer has a 135 watt power supply. If
- the disk drive(s) is(are) being installed internally, it is best to
- locate the controller in the nearest available expansion slot to the
- drive.
-
- 2. Remove the blank expansion slot bracket. Put the bracket away
- and save it for possible future use. The screw will be used to hold
- the new controller in place.
-
- 3. The terminating resistor must be present only on the last hard
- disk drive connected. If there are two drives, the terminating
- resistor must be present on the second drive. Verify proper setting
- of drive select switches for drive select 1 or 2. Refer to your
- system owner's manual for information about proper drive termination
- and select switches. DO NOT USE THE RADIAL SELECT OPTION.
-
- 4. Attach 34-pin control connector to J4 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.
-
- 5. Connect control cable to drive.
-
- 6. Attach 20-pin data connector to J3 (Drive C or 0).
-
- 7. Attach 20-pin data connector to J2 (Drive D or 1).
-
- 8. Connect data cables to drives.
-
- 9. Attach Winchester activity LED connector to J1. J1 is a
- reversible connector.
-
- 10. Install controller board into the expansion slot. Make sure that
- the board is seated properly by pressing down on both ends of the
- board. Secure the board with the bracket screw.
-
- 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.
