Introduction:

This handbook may be used for ST01/02 Host Adapter installation
or with Seagate's SCSI Paired Program. Paired Program means that
the drive and Host Adapter/Controller are matched to optimize
system throughput. And, installation software is already loaded
on the drive.

Seagate SCSI drives are recognized by an "N" after the drive
model number, e.g., ST1096N.

The ST01 and ST02 Host Adapters provide an 8-bit SCSI interface
for the IBM PC XT AT (and all 100% compatible systems) and up to
seven SCSI devices. Installation of more than two hard disc
drives requires device driver software, which is not provided by
Seagate.

The ST02 additionally supports up to two 3.5-inch or 5.25-inch
floppy diskette drives.

Seagate SCSI Host Adapters require only a single bus connector
and may be installed in a standard IBM PC short or long slot.

Before You Begin...

This guide may be used for ST01/02 SCSI Host Adapter installation; both
Paired and non-Paired applications. In either application,
ST01/ST02 setup is identical.

All Paired Program drives are shipped already formatted with a
small DOS partition. A program to install the drive, called
INSTALLR is contained in that partition. You must supply the DOS
system. Seagate Paired Program drives are easily recognized by a
"PR" label on the top cover.

Paired Program drives with formatted capacities greater than 32
megabytes are shipped with partitioning software, referred to as
Disk Manager.

Before Beginning The Installation: Inspect the drive, Host
Adapter, cables, mounting hardware and accessories, documentation
and packaging. If any item is incorrect, missing or appears
damaged, contract your Distributor/Dealer.

Shipping: Improper handling during transit/shipping accounts for
many "installation" problems. When transporting or shipping a
drive, controller or system, please ensure that they are
correctly packed in the original container and shipped via an
approved carrier.

Repair centers may refuse receipt of components improperly
packaged or obviously damaged in transit. Consult your
Distributor/Dealer for approved packing materials and carriers.

Care and Handling: Do not handle a drive/Host Adapter without
observing static-discharge precautions. A grounded wrist-strap is
preferred; if unavailable, ground yourself frequently by touching
the metal chassis of the system before handling any components.
Do not unpack the drive/Host Adapter until you are ready to
complete the installation.

Seagate disc drives do not require any preventive maintenance.
The head/disc assembly is sealed and does not contain any user
serviceable components. Do not tamper with the sealed top cover;
doing so will void your warranty.

I. SCSI Drive and Host Adapter Compatibility

The ST01/ST02 Host Adapters support Seagate SCSI interface hard
drives. Early versions of the ST01 have an 8K ROM and no
auxiliary drive power connector. The 16K version of the ST01 has
an auxiliary drive power connector and is designated as ROM
Version 2.0 or higher.

The ST02 supports up to two 3.5-inch or 5.25-inch floppy diskette
drives.

Table 1: ST02 Diskette Support

-------------------------------------------------------------
| Diskette | Capacity | Transfer Rate |
-------------------------------------------------------------
| 5.25-inch | 360 KBytes | 250 Kbits/sec |
-------------------------------------------------------------
| 5.25-inch | 1.2 MBytes | 300/500 Kbits/sec |
-------------------------------------------------------------
| 3.5-inch | 720 KBytes | 250 Kbits/sec |
-------------------------------------------------------------
| 3.5-inch | 1.44 MBytes | 300/500 Kbits/sec |
-------------------------------------------------------------

Diskette support in IBM PC-compatible systems depends upon the
operating system used and the BIOS installed on the system board.
The user may have to upgrade either the BIOS or operating system
in order to obtain the desired diskette support.

Table 2 outlines the operating system requirements for the
various diskette drive types.

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

IBM offers drive support starting at PC-DOS 3.2 for the 720 KByte
diskette and at version 3.3 for the 1.44 MByte drive. The
DRIVER.BIN module is installed via the CONFIG.SYS module at boot
time.

Microsoft offers driver support starting at MS-DOS 3.2 for the
720 KByte drive through use of the DRIVPARM and DRIVER.SYS
programs.

MS-DOS 3.3 supports both the 720 KByte and 1.44 MByte drives
using the DRIVER.SYS program.

The MS-DOS DRIVER.SYS and DRIVPARM modules are installed via the
CONFIG.SYS file at boot time.

In addition to the requirement that the operating system support
a particular diskette drive, the ROM BIOS installed on the system
board must also provide compatibility.

Table 3 indicates the diskette drives supported by the ROM BIOS
installed in the most common IBM systems.

PC compatibles that do not use an original IBM BIOS should
consult the Operations Manual supplied with their system to
determine the diskette drive support offered.

II. ST01/ST02 and SCSI Drive Configuration

Before attempting any installation read through these
instructions. Verify that the system is powered-down.

1. Remove the top cover from the system. Retain the screws.

2. SCSI Address/Parity Jumpers and Resistor Packs:

Set the SCSI ID jumper on the hard disc drive. The Host
Adapter recognizes devices by their SCSI ID number. If the drive
has parity jumpers, they must remain shorted.

* If you are installing one drive, the ID number is 0 (no
jumper).

* A second physical drive must be set as ID number 1.

* Drive Resistor Termination Packs:

If you are installing two drives, remove the resistor
termination packs from the first drive (the drive
nearest the Host Adapter on the cable).

3. Remove the Host Adapter from the protective covering. Observe
static-discharge precautions and do not touch the board
components or connectors.

4. Host Adapter Configuration Jumpers:

* Starting BIOS Address, ST01 and ST02:

C800H is the 16K BIOS address (default). For the 8K
BIOS, the default address is CA00H. If there is a board
already installed at the default address in the system,
use the jumpers to change to another address. Refer to
Figures 1-3 and Tables 4-5.

* Zero-Wait-State (0WS), ST01 and ST02:

A 2-pin jumper is provided to enable the 0WS logic for
PC ATs and compatibles that implement the 0WS control
line on the PC bus. The default configuration disables
the use of this line.


7

Optimum performance will be achieved, on PC AT
compatibles that correctly implement this signal, by
enabling this line. Refer to Figures 1-3 and Table 6.
Please consult your system manual or contact your
dealer for more information.

* Interrupt Selection, ST01 and ST02:

A 3-pin jumper is provided in order to select
interrupts. Interrupts should be disabled (by removing
the jumper) for PC/MS-DOS operating in PC XT AT
environments. This is the default configuration. Refer
to Figures 1-3 and Table 7.

* Diskette Drive Selection, ST02 Only:

The ST02 supports all four of the standard PC diskette
drive types. A jumper is provided (JP5) to restrict
diskette support PC XT functionality; that is, only 360
KByte and 720 KByte. The default setting (jumper on)
will support all types. Refer to Figure 3 and Table 8.

* Register Emulation, ST02 Only:

Many personal computers that are compatible with the
IBM PC AT check at boot time to verify that an
AT-compatible diskette/hard drive controller is
present. If not, then an XT-compatible diskette
controller is assumed and only 360 KByte diskette
drives are supported.

A jumper is provided to enable emulation of this
register (01F4H). Refer to Figure 3 and Table 9.

The default is to enable emulation. In PC and PC XT
environments, it is not used and may be safely left
installed. It should be used in PC AT compatible
systems; removing the jumper may prevent use of 1.2
MByte and other (non-360 KByte) format diskette drives.

Emulation should be disabled if the system already has
a hard disc controller installed.

5. Connect the hard drive (and diskette drive to the ST02) cables
to the Host Adapter. You may find it easier to attach the cables
before you install the Host Adapter in the system. Pin-1 on the
Host Adapter always corresponds to pin-1 at the drive connector.
Note that some cables have a colored stripe to indicate pin-1.


8

6. Install the drive in the left drive-bay, if possible, as the
power supply may obstruct the cable.

7. For ease of installation attach the cable to the drive before
you slide it completely back into position.

8. Connect the drive DC power line.

9. Verify that all connections are correct and replace the system
cover. Go on to Parts IV and V/VI for the required formatting.

III. ST02 Diskette Drive Configuration

The ST02 has two 34-pin connectors for diskette drive support. J3
is provided as an edge-connector for use with PC and PC XT
compatible diskette drive cables. J5 is a 34-pin header for use
with PC AT compatible diskette drive cables. Contact your dealer
for cables.

1. PC Setup Jumpers: There are several jumpers located on the
diskette drive that must be correctly set to perform in the PC
environment. Each manufacturer may label these jumpers
differently. Refer to the diskette drive manual supplied with
your system to determine correct jumper position.

2. Diskette Drive Select Jumpers: This header has four positions.
They are labeled DS0-3 or DS1-4 depending on the drive vintage.
For PC applications only, DS1 (older drives) or DS2 (newer
drives) are used because the drive interconnecting cable has
lines switched to accommodate a common jumper setting.

3. Diskette Terminator Jumper: This jumper is used to activate
terminating resistors for 7 of the 11 drive interface input
lines. The lines are defined by drive type and manufacturer. In
PC applications Drive A has the terminating resistor jumper
active. Drive B has no terminating jumper.


20

IV. Notes Before Formatting the Drive

The installation process will "low-level" format new physical
blocks, create DOS-compatible partitions, root directories and
file allocation tables for the entire drive. The procedure is
identical for IBM XT and AT systems, except where indicated.

All Seagate Paired Program drives are shipped with a small DOS
partition containing INSTALLR.EXE, PARK.COM, and README.1ST (a
printable supplement to this installation guide). README.1ST
contains the latest information for the drive being installed. It
can be accessed by the DOS commands: TYPE, COPY, and PRINT.

* If your drive has less than 32 formatted MBytes, you
will need one DOS-bootable diskette that has the boot
files from the version of DOS that you plan to use on
your Seagate drive. This diskette should also contain
the FORMAT program provided with DOS, and sufficient
space (approximately 5 KBytes) to save the installation
programs from the hard drive. The diskette must not be
write-protected.

* If your drive has more than 32 formatted MBytes, you
will need two diskettes; one DOS-bootable with the
version of DOS you plan to use. The second diskette
must have at least 320 KBytes available to save the
installation and Disk Manager programs. The diskettes
must not be write-protected.

* Important Note for PC AT Installations:

If you are installing your drive in a PC AT or 100%
compatible, and a hard drive is not presently attached
or operational, the hard drive count in CMOS will
already be set to zero, or no hard drives installed.

If a standard hard drive is already attached and
operating, it will be the first drive and the Seagate
Paired Program Drive will be Drive 2. It is not
necessary to change the CMOS hard drive count when
installing Seagate Paired Program drives.


21

Note to Installers and/or second drive installations: DOS assigns
a logical identifier (C, D, E...) to each partition that it
recognizes during the boot load. It assigns these letters to the
first partition on each physical drive in sequential order.
Therefore, if you have a single drive with three partitions, they
will be assigned C, D, and E.

V. Installation: Drives Less Than 32 MBytes

IMPORTANT. This Section is for Paired Program installations only.
Read Section IV before formatting. The entire software
installation routine is menu-driven and takes from ten to thirty
minutes, depending on drive size. For specific DOS questions,
refer to the DOS manual supplied with your system.

After the format is completed, the read/write heads will be
parked. At the next power-up, the system will boot from the hard
disc.

Read/Write Head Park Program: A PARK program is pre-loaded on all
Paired Program drives. The ST225N requires use of this program to
park the heads before your drive/system is transported. All other
Seagate SCSI drives automatically park the heads at power-down.

For optimum performance, format the drive installed in your
system in the same orientation in which it will be used.

1. Software Installation: START HERE

Place a DOS-bootable diskette (to boot simply means to
start the system) in Drive A and switch the power on.

2. After the boot process is complete, begin the
installation by typing:

C:INSTALLR C

Press: Enter (Return)


22

If the drive and Host Adapter are correctly installed you will
see the following display:

Seagate Disc Formatting Utility, VX.X

If you are installing a second drive, type:

D:INSTALLR D ENTER

3. Your screen should look like this:

A>C:INSTALLR C

or, A>D:INSTALLR D

After pressing ENTER (Return), you will see a screen and follow
the screen prompts.


23

VI. Installation: Drives Greater Than 32 MBytes

IMPORTANT. This Section is for Paired Program installations only.
Read Section IV before formatting. The entire software
installation routine is menu-driven and takes from ten to thirty
minutes, depending on drive size. Help is available by pressing
the F1 key. For specific DOS questions, refer to the DOS manual
supplied with your system.

At the beginning of the installation, you will be instructed
(after the boot) to remove the DOS diskette and insert a blank
formatted diskette to make a backup copy of the Disk Manager
software.

After the format is completed, the read/write heads will be
parked. At the next power-up, the system will boot from the hard
disc.

For optimum performance, format the drive installed in your
system in the same orientation in which it will be used.

1. Software Installation: START HERE

Place a DOS-bootable diskette (to boot simply means to
start the system) in Drive A and switch the power on.

2. After the boot process is complete, begin the
installation by typing:

A>C:INSTALLR C ENTER

If the drive and Host Adapter are correctly installed
you will see the following display:

Seagate Disc Formatting Utility, VX.X

If you are installing a second drive, type:

A>D:INSTALLR D ENTER


24

3. Follow the screen prompts.

If you are installing a drive with Disk Manager software, and you
already have a hard disc in your system, you must copy the
DMDRVR.SYS and CONFIG.SYS files from the Disk Manager diskette to
the existing (first, or boot) drive.

If you already have a CONFIG.SYS file on the boot drive, update
the file to include the following line:

DEVICE=DMDRVR.BIN

Refer to your DOS manual for instructions on editing the
CONFIG.SYS file.



25

VII. Troubleshooting Your Installation

If you have a problem getting the initial screen, or later
getting the system to boot:

* Check the cabling between the Host Adapter and drive.
Pin-1 on the Adapter always corresponds to Pin-1 at the
drive connector. Most cables have a contrasting color
on the cable to indicate Pin-1.

* Check the power cable to the drive. Can you hear it
spinning up?

* Verify correct hard drive SCSI ID selection.

* Verify correct BIOS address for the Host Adapter. See
Tables 4-5. If you have more than one board that uses
BIOS ROM space, each must be configured to a different
memory address. Addressing multiple boards at the same
memory location can cause problems of a seemingly
indeterminate nature.

* If you experience problems accessing your DOS partition
after installation, refer to the .REF files provided
with the Disk Manager software (drives over 32
formatted MBytes).

For system or DOS help, contact your computer system
manufacturer.

For additional installation help, contact your authorized Seagate
Distributor/Dealer.
