SYMPTOMS
========

If a GSI model 18 IDE controller is installed in the non-PCI system, Windows NT
will generate a Blue Screen with a STOP 0X0000007B (INACCESSIBLE_BOOT_DEVICE)
message.

CAUSE
=====

This problem does not occur unless the add-in controller also has some device
attached, such as a fixed disk. Because the system is not PCI, ATAPI does not
control the second channel, but ATAPI must look at the devices on the card, to
see if any are ATAPI. After ATAPI determines that it is not to use the second
channel, it goes back to the boot device and reads Cylinder 0, Head 0, Sector 1
(Partition Table / MBR). At this point, for unknown reasons, it retries the read
until the retries run out (even through the data received looks legitimate). It
then determines that the boot device cannot be accessed, which causes the Blue
Screen STOP message. The impact of this problem is small because most systems
today do not use add-in IDE controllers.

RESOLUTION
==========

To resolve this problem, contact GS-118 support at (714) 261-9744 for an updated
BIOS, version 5.02. You will need to provide a serial number for support. This
problem cannot be reproduced if the device is removed from the GSI card, even if
the card remains installed in the computer.

STATUS
======

This problem occurs when you use Microsoft Windows NT version 4.0 and a GSI
model 18 IDE controller
