Windows NT Setup may fail during SCSI detection for a variety of
reasons. In some cases, the SCSI-detection routine may conflict with
the SCSI adapter, hindering further detection and sometimes even
halting the installation. You may be able to avoid these problems by
disabling some or all of the SCSI-detection phase of Windows NT Setup.

HOW TO DISABLE THE SCSI-DETECTION ROUTINES
==========================================

If you have a SCSI adapter, you can disable all the SCSI-detection
routines except the one for your particular adapter by modifying the
TXTSETUP.INF file on Disk 1 of your Setup disks. If you have no SCSI
adapters, you can disable all the SCSI-detection routines.
 
NOTE: Before you can modify TXTSETUP.INF, you need to make a backup
copy of the first Setup disk since it is write-protected. To do so,
choose Copy Disk from the Disk menu in File Manager (or use the MS-DOS
DISKCOPY command). Make sure you use the same media type and density,
and that you modify the copy of TXTSETUP.INF, not the original.
 
Before you can disable any SCSI-detection routines, you need to know
what type of computer you have: ISA, EISA, or MCA. There are three
corresponding sections in the TXTSETUP.INF file:
 
   [SCSI.ISA.LOAD]
   [SCSI.EISA.LOAD]
   [SCSI.MCA.LOAD]
 
Go to the appropriate section for your computer and disable all the
SCSI routines you do not need by inserting the pound sign (#) in front
of each line. For example, if you had an MCA computer and wanted to
disable all the SCSI-detection routines, your [SCSI.MCA.LOAD] section
would look like this:
 
   [SCSI.MCA.Load]
   #d0,ncr53c9x
   #d0,spock
   #d0,ncrc700
   #d0,ncrc710
   #d0,aha154x
   #d0,buslogic
   #d0,fd16_700
 
After you make your changes, save the file and start Windows NT Setup
again.
