CMOS setup for AT systems
When you start up your drive for the first time, enter the CMOS
SETUP routine. This routine enables you to define a new drive in
the system BIOS. However, because the SCSI host adapter BIOS
handles all I/O procedures, you should not attempt to define the
drive type in the system BIOS. Instead, set the CMOS, or system
setup, to drive type zero, or the no hard drive installed option.
Note. If you are installing your drive in an AT system and a hard
drive is not presently installed, the CMOS drive type is
already set to zero or the no hard drive installed option.
Physical geometry for non-DOS operating
systems
When installing the drive in non-DOS operating systems, use the
following information to configure your host system:
Data cylinders
Spare cylinders
Read/write heads
Total sectors
Spindle speed (RPM)
Low-level formatting
Your drive was low-level formatted at the factory to 512 bytes per
sector. In most applications, you do not have to format it again.
However, you may need to low-level format the drive to make it
compatible with your SCSI host adapter or to change the inter-
leave. See your host adapter manual for details.
