Chapter 5 SCSI Drive Installation 79
Installation
Procedure 1
This procedure assumes UNIX is already installed on an IDE,
ESDI, or ST506 hard disk drive. It will show how to include the
device drivers needed to access SCSI devices installed after the
non-SCSI drives. This installation is necessary to build a new
UNIX kernel which includes the NCR SCSI device drivers. The
basic steps for accomplishing this are outlined below. Further
detail on UNIX installation can be found in the SCO UNIX
System Administrator’s Reference manual.
1. NCR recommends creating a second copy of UNIX.
Log in as root and issue the command:
cp /unix /unix.good
This creates a second copy of UNIX under the name
/unix.good.
Note:
If any problems arise with the kernel being built in
UNIX, this procedure ensures that a valid copy of
UNIX will be available.
To access this valid UNIX copy, type at the colon after the boot
message:
unix.good
To replace the system UNIX with the working UNIX copy, type
at the system prompt:
cp /unix.good /unix
2. Install the NCR SDMS SCSI UNIX device drivers.
a. Insert the SCO SDMS SCSI Drivers floppy diskette in the
drive and type:
installpkg
Press the Enter key to continue.
b. A prompt will appear to insert the requested floppy diskette.
Since the NCR diskette has already been inserted, press the
Enter key to continue.
