SUMMARY
Windows NT may no longer start (boot) after you remove an adapter.
This is because Windows NT stores references to adapters statically.
When you remove an adapter, the adapter number may change at the
hardware level. For example, if you had two SCSI hard disk
controllers, numbered 0 and 1, removing the first will make the second
become number 0. When Windows NT tries to access the information on
the second adapter, it looks for adapter number 1, which no longer
exists.
If this problem occurs, you need to modify an entry in the BOOT.INI
file to accurately reflect the adapter number. For example, the
following entry may be in the BOOT.INI file:
scsi(1)disk(0)rdisk(0)partition(1)\winnt = "Windows NT 3.1"
/SCSIORDINAL:0
In the previous example, you would need to change the value in SCSI(1)
to SCSI(0).
Note: On non-x86 - based computers, you need to modify system boot
parameters.
In general, you should disable an adapter and test to see if Windows
NT boots before physically removing it. In this manner, if Windows NT
fails to boot, you can power down and restart Windows NT to revert to
the last known good control set.
