The first menu displays the Configure/View Host Adapter Settings and SCSI Disk Utilities options.

Using SCSISelect Menus

SCSISelect uses menus to list options you can select. To select an option, use the up- and down-arrow keys to move the cursor to the option; then press <Enter>.

In some cases, selecting an option displays another menu. You can return to the previous menu at any time by press- ing <Esc>. To restore the original SCSISelect default values, press <F6>.

Using the SCSI Disk Utilities

To access the SCSI disk utilities, select the SCSI Disk Utilities option from the menu that appears when you start SCSISelect. Once the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID.

When you select a specific ID and device, a small menu appears, displaying the Format Disk and Verify Disk Media options.

Format Disk. This option runs a utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI disk drives are formatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the

vast majority of SCSI disk drives.

.

CAUTION: The Format Disk option destroys all data on the hard-disk drive.

Verify Disk Media. This option runs a utility that allows you to scan the media of a hard-disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select Yes, those blocks are no longer used. You can press <Esc> at any time to exit the utility.

Exiting SCSI Select

To exit SCSISelect, press <Esc> until a message prompts you to exit. (If you changed any 78xx series host adapter settings, you are prompted to save the changes before you exit.) At the prompt, select Yes to exit, and then press any

key to reboot the computer. Any changes you made in SCSISelect take effect after the computer boots. (You can select No at the prompt if you are not ready to exit SCSISelect.)

Installation Overview

This section provides the information needed to install and use the Dell SCSI drivers for the 78xx series of SCSI controllers with the Windows NT operating system.

The Windows NT 3.51 driver diskette you create for the Microsoft Windows NT Server 3.51 operating system contains the files needed for driver installation. The \scsi subdirectory on the diskette contains the following files to be used with Windows NT 3.51:

aic78xx.sys — Adaptec’s 78xx Family driver for Windows NT

oemsetup.inf — A file used by Windows NT Setup for driver installation

readme.txt — A text file describing the Adaptec 78xx driver for Windows NT

If you are performing a first-time Windows NT installation, see the following subsection, “Installing Windows NT 3.51 and the Driver,” to begin driver installation. If Windows NT is already installed in your system, see “Using Windows NT to Install or Update the Driver” found later in this section.
