Installing and Configuring SCSI Drivers 3-29
Troubleshooting for Windows NT
The boot manager for Windows NT contains recovery
logic to allow you to return to the last known good
configuration. If you have changed your host adapter
configuration and Windows NT no longer boots, follow
these steps to recover:
1. Undo any hardware changes you have made to
the computer since it was last operational.
2. Reboot the computer. Watch the display carefully
during start-up. If the following message appears,
press the <Spacebar> and follow the instructions
on the screen to continue booting with the last
known good configuration:
Press spacebar NOW to invoke the Last
Known Good menu
3. Once your computer is operational again, check
all of the hardware and software configuration
changes you want to make. Look specifically for
conflicts with parts of the existing system configu-
ration that are not being changed.
If you cannot determine the source of the error, contact
Dell for assistance. See Chapter 8, “Getting Help,” in the
Diagnostics and Troubleshooting Guide for instructions
on contacting Dell for technical assistance.
Installation for Novell NetWare
Read this section to find out about the NetWare operating
system installation, including:
•Installing the EZ-SCSI utility
•Calculating the slot number
•Installing and/or updating the Dell SCSI driver for
NetWare
•Using command line options that can be specified
when the driver is loaded
•Automatic driver loading using startup.ncf and
autoexec.ncf
•Booting a NetWare server from a SCSI drive, for-
matting media, and using removable media

Installation Overview
This section provides the information needed to install
and use the Dell SCSI drivers for NetWare 3.12 and 4.x.
The Dell SCSI drivers for NetWare support the optional
Adaptec AHA-2940UW and all Adaptec 78xx series
SCSI controllers.
Before you begin installation of the SCSI drivers for
Novell NetWare, you must create a diskette of drivers for
the version of NetWare you are using (3.12 or 4.x) and a
diskette that contains the Adaptec EZ-SCSI utility. Chap-
ter 2, “Using the Dell Server Assistant CD,” provides
instructions for creating these diskettes.
NOTE: Be sure to use the SCSI Driver diskettes created
from the Dell Server Assistant CD rather than the SCSI
drivers provided with the operating system.
The Dell SCSI drivers for NetWare are fully NetWare-
tested and approved. The NetWare \scsi subdirectory on
the NetWare 3.12 drivers diskette you create contains
files to be used with NetWare 3.12. The \scsi subdirectory
on the NetWare 4.x drivers diskette you create contains
files to be used with NetWare 4.x. The following files
appear in the \scsi subdirectories on both NetWare driver
diskettes:
•readme.txt — An American Standard Code for
Information Interchange (ASCII) text file describing
Adaptec’s drivers for NetWare
•aic7870.dsk — Adaptec’s 78xx Family driver for
NetWare
•aspitran.dsk — Adaptec’s ASPI® transport layer
driver for NetWare
•aspicd.dsk — Adaptec’s device driver for a
CD-ROM drive
In addition, the \scsi subdirectory on your NetWare 4.x
drivers diskette contains the following files:
•aic7870.ddi — A driver definition information file
to provide setup information to NetWare during
installation; NetWare can then prompt you with
parameters to be configured for the device driver
during the installation process.
•aspicd.ddi — A device driver definition file.
•aspitran.ddi — A device driver definition file.
