Chapter 3

Installing and Configuring SCSI Drivers

This chapter describes how to install and configure the Dell small computer system interface (SCSI) device driv- ers included with your Dell PowerEdge 2100 computer system. These device drivers are designed to work with the Adaptec AIC-7880 Ultra/Wide SCSI controller chip on the system board.

Both the built-in AIC-7880 and the optional AHA-2940UW SCSI controller card are all part of the Adaptec 78xx series of SCSI controllers, and use the 78xx series of SCSI drivers Dell provides. The Adaptec SCSI basic input/output system (BIOS), which is stored in your computer system’s flash memory or on the optional AHA-2940UW SCSI controller card, links these SCSI device drivers to the built-in AIC-7880 or the optional AHA-2940UW SCSI controller card.

For instructions on installing SCSI hardware devices such as hard-disk drives, tape drives, or CD-ROM drives, see Chapter 8, “Installing Drives in the External Bays,” and Chapter 9, “Installing Drives in the Internal Bays.” For information on SCSI configuration guidelines (SCSI iden- tification [ID] numbers and termination requirements), see “SCSI Configuration Guidelines” in Chapter 9.

After the SCSI devices you plan to use are installed, you may need to install and configure 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.

The 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.

The SCSISelect Utility

The BIOS for the built-in Adaptec AIC-7880 controller includes the menu-driven SCSISelect configuration util- ity, 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.

SCSI Select Default Settings

Default settings for the optional Adaptec AHA-2940UW SCSI controller and the built-in AIC-7880 SCSI control- ler 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.

NOTE: The term host adapter is used throughout this chapter to refer to the built-in AIC-7880 SCSI controller or the optional AHA-2940UW SCSI controller card.

For situations in which you might want or need to change the settings, see the descriptions of each setting in the fol- lowing subsections. To change any of the default settings or to format or verify a disk, see “Starting the SCSISelect Utility” found later in this chapter.
