Setup Hangs During SCSI Detection; Disabling SCSI Detection (103471)

SUMMARY

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.
