Using GSI Model 18 Add-in IDE Controller Causes STOP 0x7B (163897)
The information in this article applies to:
- Microsoft Windows NT Server 4.0
- Microsoft Windows NT Workstation 4.0
This article was previously published under Q163897 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
