INSTALLING SEAGATE'S RLL PAIRED SOLUTIONS
I. INTRODUCTION
Seagate's ST11R controller and RLL drive package offers a complete RLL
Paired Solution. This section of the database will assist you in the
installation of your Seagate RLL drive and controller. Before beginning,
please read through the entire section.
Seagate provides partitioning software pre-loaded on the drive for drives
over 32 formatted Mb.
BEFORE YOU BEGIN...
- Seagate RLL Paired Program disc drives are shipped to you already
formatted with a small DOS partition. The programs necessary to install
the drive are contained in that partition. You must supply the DOS* system
programs. You will be prompted with display screens at each step in the
installation process. Paired Program drives with formatted capacities
greater than 32-Mb are shipped with software to access multiple
partitions or partitions larger than 32 Mb.
* DOS is a registered trademark of Microsoft Corporation
- REFER TO THE MATRIX IN TABLE 1 FOR SEAGATE DRIVES SUPPORTED BY THE
ST11R.
- A printable README file, containing supplemental installation
information, is included with the installation software and is accessible
via the DOS system commands.
- The ST11R is designed to be installed only with drives certified for
RLL (2,7) data encoding. Use with Seagate drives designed for MFM-only
data encoding will void your drive warranty. Even though an MFM drive may
initially format correctly with an RLL controller, performance may
degrade over time. Seagate assumes no liability for installation of an
RLL controller with an MFM-certified disc drive.
- 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.
- When transporting or shipping a drive, controller or system, please
ensure that they are correctly packed in the original container and
shipped via an air-ride carrier.
- Installation Warning: Do not touch the board components or connectors
without observing static-discharge precautions. A grounded wrist-strap is
preferred. If that is unavailable, ground yourself by touching the metal
chassis of the system before handling any components. Do not unpack the
components until you are ready to install them in the system.
- Do not install the ST11R controller and apply power without first
removing the rubber strips from all connectors on the controller. These
strips are conductive. Failure to observe this warning will void the
controller's warranty and can cause serious problems in your system.
ST11R Controller and Drive Compatibility
The ST11R supports up to two (2) of the following drives:
Table 1
Drive Formatted MB Cylinders* R/W Heads Sectors
ST138R 32.7 615 4 26
ST157R 49.1 615 6 26
ST225R 21.0 667 2 31
ST238R 32.7 615 4 26
ST250R 42.3 667 4 31
ST277R 65.5 820 6 26
ST4144R 122.7 1,024 9 26
* Maximum cylinders per drive.
Usable cylinders are reduced by:
a) One (1) cylinder for drive geometry and defect information.
b) One (1) cylinder for diagnostic area.
c) One or more cylinders for alternate tracks. Alternate track assignment
is only made if defects involve more than one sector on a track. Single
sector defects are compensated for within the track on which they occur.
Alternate track assignment is only made when installing a drive through
the BIOS (e.g.,DEBUG,-G=C800:5) or with the INSTALLR installation program
(see Section IV.).
II. ST11R Controller Setup
1) Remove the ST11R from the protective covering and pull the conductive
rubber strips from between the pins at the J1, J2 and J3 headers. These
strips provide static-discharge protection during transit. FAILURE TO
REMOVE BEFORE INSTALLATION CAN CAUSE SERIOUS PROBLEMS IN YOUR CONTROLLER
AND SYSTEM.
2) Configure the ST11R:
C8000h is the default BIOS address. If there is a board already installed
at this address in you system, use the jumpers provided to change to
another address. Locations A and B are the two pins toward the front of
the system and D and C are the two pins toward the back of the system.
Refer to the documentation provided with your system and other peripheral
devices to determine if there is an address conflict. See Table I below.
The ST11R has four possible starting addresses:
Table 2
CONFIGURATION BIOS ADDRESS PORT ADDRESS
No Pins Shorted C8000h (default) 320h - 323h
Pins A-B shorted D0000h 324h - 327h
Pins C-D shorted D8000h 328h - 32Bh
Pins A-B & C-D shorted E0000h 32Ch - 32Fh
When installing the ST11R in a system that does not contain any other
hard disc controllers, all jumpers should be removed from the BIOS PROM
address jumper. The ST11R is shipped with the correct configuration for
one hard disc controller.
When installing the ST11R in a system with the Seagate STO1 SCSI Host
Adaptor, the ST11R must be configured at a lower BIOS address than the
ST01.
When installing the ST11R in a system already containing a hard disc
controller, the ST11R must be jumpered at a higher BIOS address than the
other controller. If you are not sure of the other controller's address,
try one of the higher addresses for the ST11R (e.g.,D8OOOh or E0000h).
3). The J5 header on the ST11R may be used to provide disc drive power
for systems lacking auxiliary power connectors. See your Dealer for
cabling. Note: Some early configurations of the ST11R may not include the
J5 header.
J5 is pinned out as follows:
Pin Signal Description
1 +12 VDC + 12 Volt DC Supply
2 +12 VDC + 12 Volt DC Supply
3 +5 VDC + 5 Volt DC Supply
4 GND Pin removed for connector key
5 GND Ground
6 GND Ground
Note: Pin 1 is toward the from and top of the system and also indicated by
a square solder through pad on the ST11R.
III. Drive Configuration And Installation
Prior to installation, rest the drive on a padded anti-static surface;
never on an unprotected hard surface.
Do not touch the board components or connectors without observing static-
discharge precautions. A grounded wrist-strap is preferred. If that is not
available, ground yourself by touching the metal chassis of your system
before handling any components.
VERIFY THAT THE POWER IS OFF. Remove the top cover from your system.
Access to the top cover screws is via the back of the system. Save the
screws.
1) Drive Select Jumpers:
2) Installation of one drive requires a jumper at its Drive Select 1
position. Note: Drive select 1 is selected by shorting the 2 pins closest
to where the 20 pin connector plugs into the drive. With one exception,
noted in bullet 4 below, the second drive must have its Drive Select
jumper at the DS2 position. Drive select 2 is one set of pins over from
the drive select 1 position.
Note: Check that there also is a jumper installed at position 7 on the
Drive Select header. There should be only two jumpers installed at the
Drive Select header.
3) Drive Resistor Termination Packs:
If you are installing a single drive, the resistor termination pack must
remain installed. If you are installing two drives, remove the pack from
the drive connected at the middle of the 34 pin cable.
When installing the resistor termination packs, note that pin-1 is
