Introduction

This installation guide provides step-by-step instructions on install-
ing your AHA

®

-2910C host adapter. This process involves installing 

the following hardware and software:

AHA-2910C host adapter

Internal SCSI devices

External SCSI devices

AHA-2910C software

You will also find helpful hints on configuring your SCSI 
devices and customizing your host adapter settings with SCSISelect

.

The AHA-2910C host adapter provides a powerful multitasking 
interface between your computer’s PCI bus and internal and external 
SCSI devices (disk drives, CD-ROM drives, tape drives, removable-
media drives, etc.). The host adapter supports SCSI Configured 
AutoMatically (SCAM), which automatically assigns SCSI IDs to 
SCAM compatible devices. The figure below identifies the major com-
ponents of the AHA-2910C host adapter. 

With the Adaptec software drivers, you can use AHA-2910C host 
adapters in computers running DOS/Windows

, OS/2, 

Windows
