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:

1. Start Registry Editor (REGEDT32.EXE) and select the following subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Fd8xx
  \Parameters\Device0

2. Double-click the value DriverParameter:REG_SZ:IRQ=5.

3. Enter the following string

  IRQ=<value_nr>

  where "<value_nr>" is the new value on which the controller operates

4. Quit Registry Editor and restart Windows NT (or Windows NT Advanced Server).
