read the screen. This may include garbled output, white screen, black
screen, or an out of sync message from the monitor.

limits of the monitor. You will need to boot Windows in Safe Mode. To do
this, reboot the controller. As Windows begins to boot, hold down <F8>.
For Windows NT, select
Windows NT (VGA MODE)
from the boot
manager. You should now be able to reset the video driver to lower settings.

What if there is a power loss during a BIOS update?
Create a crisis recovery disk. Unzip
crisis.zip
on the recovery
CD. Insert a blank floppy disk in the PC. Run
crisis.exe
(or
Wincrisis.exe
in Windows). Follow the instructions to create the
BIOS recovery floppy disk. Insert the disk in the floppy drive and
power on the controller. The controller installs the BIOS from the disk.
