SYMPTOMS

When you are using an Intel motherboard with an AMI/Intel BIOS or an Iomega IDE Zip drive installed on the secondary IDE channel, you may receive a "Fatal Exception Error" error message when you start the computer without a disk in the Zip drive or you eject the disk from the Zip drive.

CAUSE

This problem can occur if the following conditions exist:

The computer has an IDE removable drive that uses Media Status Notification (the Iomega IDE Zip drive is one such drive).
The computer's BIOS unmasks the PIC for the IRQ on the controller on which the drive is located.
The drive is accessed with no disk in the drive.
The BIOS touches the Alt Status register when an interrupt is vectored to it.

When these conditions exist, an interrupt may be reflected to the BIOS, which can cause a fault.
