Chapter 3 – SCSI Installation

Chapter 3 SCSI Installation

Introduction

This chapter describes how to install the SCSI Device Controller Module.

The SCSI Module provides two software interfaces: the drivers and the

BIOS. The drivers are files loaded by the CONFIG.SYS file as devices.

They reside in system RAM. The BIOS is an extended BIOS which resides

as an 8-bit entity on the AT bus. Either the BIOS or the drivers may be used

for system booting. The user must decide which is appropriate for the given

application.
The following are mutually exclusive options to be considered in deciding to

use BIOS or the drivers:

Only the BIOS supports booting from the SCSI interface. The drivers

cannot be used in these applications

The drivers' location in system RAM provides faster SCSI interactions

The BIOS may only be used in systems with one or no standard hard

drives. There must be no more than two drives, (standard and SCSI), in

the system. The drivers support up to 56 devices and must be used when

more than two are needed.

The BIOS is configured via switches on the module which is typically

embedded in the system. The drivers are configured via parameters in

the CONFIG.SYS file.

The BIOS only recognizes SCSI targets 0:0 and 1:0. The drivers must

be used to access other targets.

The BIOS only works with drives. The drivers must be used to access

other types of SCSI devices.

The drivers support multi-tasking. The BIOS does not.

Removable media hard disks should

only

be installed under the drivers.

If installed under the BIOS,

do not change media

or unpredictable re-

sults may occur or data may be lost.

Note

Users may boot from one SCSI drive using the BIOS, and then

attach other SCSI devices by using the drivers. The drivers will

be installed when the config.sys file is run from the first SCSI

drive. (See “Booting from a SCSI Drive” section later in this

chapter).
