III. Preparing The Drive For Use
The installation process will low level format new physical blocks on
the entire surface of the drive and will create DOS compatible parti
tions, root directories, and file allocation tables.
All drives are shipped
wit~
a small DOS partition containing
INSTALLR.EXE, PARK.EXE and README. 1ST (a 3-page 'printable
suppliment to this installation guide). README.1ST will contain the
\
\'
latest installation information for the drive being installed and can be
accessed by DOS system comrhands: TYPE, COpy or PRINT.
Drives having more than 32 formatted megabytes are shipped with
additional installation software resident, hereafter referred to as Disk
Manager. This software supports multiple DOS partitions on a single
drive and partitions greater than 32 MB. Program execution will begin
automatically. In addition, a number of reference files (.REF) provide
information concerning the process. These files can be accessed by
DOS system commands: TYPE, COPY or PRINT.
If your disc drive has less than 32 formatted megabytes, you need one
DOS bootable diskette that has the boot files from the version of DOS
that you plan to use on your Seagate disc drive. This diskette should
also contain the FORMAT program provided with your DOS system,
and sufficient space (approximately 50 KB) to save the installation
programs from the hard disc. This diskette must not bfl write protected.
If your disc drive has more than 32 formatted megabytes, you need
two diskettes to
cOJTlpl~te
the installation process. The first of these
diskettes need only be DOS bootable with the version of DOS that you
plan to use on your hard disc drive. The second diskette must not be
write protected, and have at least 320 KB of free space to save the
installation and Disk Manager programs.
If you are installing your drive in a PC AT or compatible machine and
a standard hard drive is not presently attached or operational, the
hard drive count in CMOS RAM will be set to zero. It is not necassary
to change the CMOS RAM hard drive count when installing SCSI drives.
If a standard drive is already attached and operational in your system,
it will be the first drive and the Seagate SCSI drive will be the second
drive. The CMOS RAM hard drive count should not include the Seagate
SCSI disc drive.

If you are installing a second drive in your system and Disk Manager
is used to install it, it is important that the Disk Manager driver
(DMDRVR.BIN) is resident on the boot drive and a "device
=
DMDRVR.BIW statement js contained in the CONFIG.SYS file on that
drive. Normally this statement should follow any "device
="
statement
for the boot drive.
WARNING TO INSTALLERS OF SECOND DRIVES: DOS a88lgns a log
lcalldentlfler (e.g. C, D, E •••) to each partition that It recognizes during
the boot load. Furthermore, DOS assigns Identifiers to the first partition
on each physical drive before asslgnfng Identifiers to additional par
titions. Therefore, If you have a single drive with three partitions, they
will be assigned C, D and E. However, when the second drive Is In
stalled, the first partition on drive 1 will be assigned C, the first partition
on drive 2 will be assigned D, then E and F will be assigned to the
remaining partitions on drive 1. Any additional partitions on drive 2
then will be aSSigned subaequentldentlflers. Ills Important to realize
that the partitions previously Identified as D and E have changed when
the second drive Is added.
The PARK program supplied with your drive is used to park the read/
write heads for the ST225NPR only. All other drives automatically park
their heads at power-off. For your own protection, you should always
park the read/write heads before your system is transported.
Procedure
1. Place a DOS-bootable diskette in drive A and switch the power
on. If you have correctly installed the drive and adaptor, ST01
SCSI Host Adaptor Vx.x will be displayed, followed by a screen
prompting you to the next step. Each step in the process is lead
by screen prompts.
2. After the boot process is complete, begin the installation by typing:
C:INSTALLR C, or if you are installing a second hard drive,
D:INSTALLR D.
