INSTALLING THE ST01 HOST ADAPTOR
WITH A SEAGATE SCSI DISC DRIVE
I. Introduction
Seagate reserves the right to change, without notice, the specifications
contained in this file.
The ST01 provides the connection between the IBM PC XT/AT* (or compatible)
and up to two Seagate SCSI drives.
*IBM PC XT/AT are registered trademarks of International Business Machine
Corporation.
-The ST01's onboard software will assist you with the required formatting
operation.
-Drive's with more than 32 formatted megabytes require device driver
software for formatting. Seagate currently ships partitioning software
only with drives greater than 32 formatted megabytes.
Before attempting installation read through these instructions and verify
that the system is powered-down.
II.ST01 AND Disc Drive Installation
1. Remove the top cover from the system. Retain the screws.
2. Set the SCSI ID jumper on the disc drive. The ST01 recognizes devices
by their SCSI ID number.
-If you are installing one drive, the ID number is O (no jumper). The
drive is shipped with ID set to zero.
-A second physical drive must be set as ID number 1. ID number 1 is
selected by placing a shorting jumper on the set of shorting pins
furthest away from the 50 pin cable connector on the drive. If you are
installing two drives, remove the resistor termination packs from the
first drive.
-Note: If the drive has a parity jumper, it must remain shorted. The
parity jumper is the set of pins closest to the 50-pin cable connection on
the drive.
3. Remove the ST01 from the protective covering and pull the rubber
strips from between the connector pins. Observe static-discharge
precautions and do not touch the board components or edge-connectors.
4. Set the starting address on the ST01.
-CA000 is the default BIOS address. If there is a board already installed
at this address in the system, use the jumpers to change to another
address. See table 1.
Table 1: ST01 Host Adaptor
There are four possible starting addresses for the ST01 BIOS
Configuration Address
No jumpers installed CA000 (default)
Pins A-B shorted (top 2 pins) C8000
Pins C-D shorted (bottom 2 pins) CE000
Pins A-B & C-D shorted: DE000
-A two-pin jumper is provided near the bottom of the Host Adaptor to
disable the zero-wait-state (0WS)logic for some PC XT/AT look-alikes that
do not use the 0WS control line. If the default configuration does not
work properly, remove the jumper to disable this line.
5. Connect the cable to the ST01. You may find it easier to attach the
cable before you install the ST01 in the system.
-Pin-1 on the ST01 corresponds to pin-1 at the drive connector. Note that
some cables have a contrasting-color stripe to indicate pin-1.
6. Install the ST01 into an available bus slot. For PC XT applications
only: DO NOT USE slot number eight, which is next to the power supply.
7. Install the drive in the left-drive bay, if possible, to be sure that
the power supply does not obstruct the cable.
-For ease of installation attach the cable to the drive before you slide
it completely back and into position.
-Minimum required for mounting: 4, 6-32 UNC-2B x 0.31 inch screws. Snug
the screws down evenly to approximately 8-inch pounds. DO NOT
OVER-TIGHTEN.
8. Connect the drive DC power line.
9. Verify that all connections are correct and replace the system cover.
Go to section III for the required formatting operation.
III. Formatting a Drive with the ST01
At power-on the ST01's onboard program will assist you by means of
help-screens. Follow the short steps. You will need the DOS* diskettes
and manual which came with your system. VERIFY CORRECT INSTALLATION, TURN
ON THE SYSTEM AND FOLLOW THE SCREEN INSTRUCTIONS.
*DOS is a registered trademark of Microsoft Corporation.
1. You will be instructed to run the DEBUG program followed by the
starting address.
2. When the low-level format is complete, you will be instructed to run
the FDISK and FORMAT programs. Some versions of DOS have different names
for these two programs. See your DOS manual.
-The FDISK program will instruct you to strike any key to restart the
system. Disregard this instruction. INSTEAD, PRESS THE CTRL-ALT-DEL KEYS
SIMULTANEOUSLY TO RESTART THE SYSTEM. Striking keys other than Ctrl-Alt-
Del may prevent booting form the hard disc. If you accidentally press
other keys, rerun the formatting program, using the DEBUG program.
3. If you have a problem getting the system to boot:
- Check cabling: Pin-1 on the ST01 corresponds to pin-1 at the drive.
- Verify correct SCSI ID number set at the drive.(See section II)
- Verify correct address and 0WS jumper setting on the ST01.(See Table 1)
IV. Read/Write Head Parking Utility
If you are transporting the system or shipping the disc drive, and wish
to park the read/write heads, run the DEBUG.com program and type g=CA000
followed by Return.
This routine applies only to the ST225N. All other Seagate intelligent
drives will automatically park the heads at power-down.
Note: IF YOU HAVE CHANGED THE ST01 BIOS ADDRESS JUMPER (TABLE 1), YOU
MUST ENTER THIS ADDRESS IN PLACE OF CA000.
