Configuring the SCSI Subsystem

You can easily configure the SCSI controller, BIOS, and devices
for both channels using the EISA Configuration utility on your
computer’s System Configuration diskette.

The EISA Configuration utility includes a SCSI disk formatting
utility so you can format your SCSI devices as you configure

your system. See Chapter 3 for instructions on using the EISA

Configuration utility to configure your SCSI subsystem.

Installing SCSI Software

The SCSI driver diskettes include drivers and driver
installation programs for the operating systems mentioned
above. The EZ-SCSI program installs SCSI device drivers for
the following versions of DOS:

MS-DOS and IBM DOS 3.30 and 4.0x

MS-DOS 5.0 and 6.X

Compaq

®

DOS 3.31

For instructions on using EZ-SCSI and its related ASPI utilities,
and on loading the drivers and managers into high memory,
see Chapters 1 through

5

of your

X-Series SCSI Software User`s

Guide for the AIC-7770.

Appendices D and E of that manual

describe the functioning of the drivers and utilities EZ-SCSI
installs.

The SCSI driver diskettes also contain the ASPI Manager Set
which supports NetWare, OS/2, and UNIX. See Chapters 6
through 9 of the

SCSI Software User's Guide

for instructions on

using the manager for one of these operating systems.
