Configuring IRQ of Future Domain 8xx SCSI Controller
ID: Q108411
|
The information in this article applies to:
-
Microsoft Windows NT operating system version 3.1
-
Microsoft Windows NT Advanced Server 3.1
SUMMARY
By default, the Future Domain 8xx SCSI controller operates with IRQ set to
1. If the adapter is configured to use a different interrupt, the
corresponding registry entry needs to be changed manually.
MORE INFORMATION
The Setup applet of the Future Domain SCSI adapter does not have a dialog
box that you can use to change any settings for the adapter. All settings
in the registry are automatically set to their default values. As a result
of this, if the IRQ level of the adapter is set to a non-default value
(such as any number other than five), the system will not start properly.
WARNING: Using the Registry Editor incorrectly can cause serious, system-
wide problems that may require you to reinstall Windows NT to correct
them. Microsoft cannot guarantee that any problems resulting from the
use of Registry Editor can be solved. Use this tool at your own risk.
Modify the value "DriverParameter:REG_SZ:IRQ=5" in the following way:
- Start Registry Editor (REGEDT32.EXE) and select the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Fd8xx
\Parameters\Device0
- Double-click the value DriverParameter:REG_SZ:IRQ=5.
- Enter the following string
IRQ=<value_nr>
where "<value_nr>" is the new value on which the controller operates
- Quit Registry Editor and restart Windows NT (or Windows NT Advanced
Server).
