The methods used to configure system BIOS vary from system
to system. In many cases, you can run a setup program from the
DOS prompt. In other cases, you must initiate BIOS setup by
pressing certain keys while the system is booting up.
Within the setup program, there are three possible ways that you
can specify your drive type:
•Match your drive specifications (from the table below) with
those of a drive type specified in the setup program.
•Specify a custom or user-defined drive type in the setup
program, then manually enter your drive specifications from
the table below.
•Select specifications lower than those required for your drive,
and allow your drive to mimic the drive type selected.
Drive Specification ST9100A and ST9100AG
No. cylinders 748
No. read/write heads 14
No. sectors per track 16
Total No. sectors 167,552
Capacity (Mbytes)
BIOS calculated 81.8
Usable 85.8
When the drive specifications are entered manually as a user-
defined or custom drive type, the BIOS should display a drive
capacity equal to the
BIOS calculated capacity in the table above.
This value will be lower than the usable drive capacity.
