Introduction; Configuring The Scsi Adapter - Advantech PCA-6166 User Manual

6.1

Introduction

The PCA-6166S/F is equipped with an Adaptec AIC-7890 single-chip
PCI-to-SCSI host adapter which provides a powerful Ultra2 multitask-
ing interface between your computer's PCI bus and SCSI devices
(disk drives, CD-ROM drives, scanners, tape backups, removable
media drives, etc.). Up to a total of 15 SCSI devices can be connected
to the SCSI connector on AIC-7890.
The Adaptec AIC-7890 is a 16-bit, LVD/SE (Low Voltage Differen-
tial/Single-Ended) SCSI solution for your computer. It can support
both legacy Fast SCSI and Ultra SCSI devices, as well as the newest
LVD Ultra2 SCSI devices.
If you need to configure the SCSI, the on-board SCSI Select configu-
ration utility allows you to change host adapter settings without
opening the computer or handling the board. In addition, the SCSI
Select utility contains a utility to low-level format, and it verifies the
disk media on your hard disk drives.

If any peripheral is attached to the Ultra2 SCSI
segment and is running at SE mode, one or more
Ultra/Ultra Wide peripherals will be attached to the
Ultra2 SCSI segment and will cause the Ultra2 SCSI
segment to run at speeds up to 40 MBytes/sec
instead of 80 MBytes/sec.
