Installing and Configuring SCSI Drivers

T
his chapter describes how to install and configure the
Dell small computer system interface (SCSI) device driv-
ers included with your Dell PowerEdge 4100 computer
system. These device drivers are designed to work with the
Adaptec AIC-7880 Ultra/Wide SCSI controller chip and
AIC-7860 Ultra/Narrow SCSI controller chip on the sys-
tem board. The AIC-7880 supports up to six internal
SCSI hard-disk drives via a standard SCSI backplane
board, while the AIC-7860 supports up to four externally-
accessible SCSI devices in the system's external drive
bays.
The AIC-7880, AIC-7860, and the optional AHA-2940
SCSI controller card are all part of the Adaptec 78xx series
of SCSI controllers, and all use the 78xx series of SCSI
drivers provided by Dell. The Adaptec SCSI basic input/
output system (BIOS), which is stored in your computer
system's flash memory or on the optional AHA-2940 SCSI
controller card, links these SCSI device drivers to the AIC-
7880 and AIC-7860 SCSI controller chips or the optional
AHA-2940 SCSI controller card.
For instructions on installing SCSI hardware devices such
as hard-disk drives, tape drives, or CD-ROM drives,
trained service technicians should see Chapter 9, "Install-
ing Drives in the External Bays," and Chapter 10,
"Installing Drives in the Internal Bays," in the Installation
and Troubleshooting Guide. After the SCSI devices you
plan to use are installed, you may need to install and con-
figure one or more SCSI device drivers so that your SCSI
devices can communicate with your operating system.
SCSI device drivers are provided for the following oper-
ating systems:
•
Microsoft Windows NT Server 3.51
•
Novell NetWare 3.12 and 4.x
See Chapter 2, "Using the Dell Server Assistant CD," for
instructions on creating a diskette of drivers for your
operating system. For instructions on configuring the
SCSI device drivers, see the appropriate sections in this
chapter.
T
he readme.txt File
The readme.txt file that is included with your SCSI
device drivers (in the \scsi directory on the CD) provides
updates to the information in this chapter.
Use the editor included with your operating system to
view or print the readme.txt file or any other readme
file.
T
he SCSISelect Utility
The BIOS for the built-in Adaptec AIC-7880 and AIC-
7860 SCSI controllers includes the menu-driven
SCSISelect configuration utility, which allows you to
change SCSI controller settings without opening the
computer. SCSISelect also contains SCSI disk utilities
that let you low-level format or verify the disk media of
your SCSI hard-disk drives.

SCSISelect Default Settings

Default settings for the optional Adaptec AHA-2940
SCSI controller and the built-in AIC-7880 and AIC-7860
SCS controllers are shown in Table 3-1. These default
settings are appropriate for most Peripheral Component
Interconnect (PCI) systems. Run SCSISelect only if you
need to change any of the default settings.
