Error Message: ACPI BIOS Is Attempting to Write to Illegal IO Port Address

[Paul]

Recently my computer has been shutting itself off without
warning. It began when I was using Windows ME and I
thought it was a problem with the O/S. I recently
upgraded to XP, hoping that the problem would be fixed.
Two things happened. Unfortunately, the problem was not
fixed. Fortunately, because of XP's error log, I was able
to identify the problem.

The error message being shown is:

Error Message: ACPI BIOS Is Attempting to Write to
Illegal IO Port Address

Event Type: Error

Description:
AMLI: ACPI BIOS is attempting to read from an illegal IO
port address (0x71), which lies in the
0x70 - 0x71 protected address range. This could lead to
system instability. Please contact your
system vendor for technical assistance.

After reading Microsoft Knowledge Base Article - 283649
concerning this subject, in which it recommended that I
contact the vendor for a BIOS update, I realized that the
problems actually began a while back AFTER I installed a
BIOS update.

My questions are:

1. Why does my computer shut down because of this
attempted read/write?

2. How can I fix it? Is there a way to revert back to the
old BIOS? Or can I block off that portion of memory so
that the BIOS will not attempt to write to the memory
block?

Any help that you can give me would be greatly
appreciated.

Hi, not sure if that particuar error message will actually cause your PC to
shut down and there could be other factors involved. However this error is
caused by your bios not being compatible with XP and you'll need to go to
your motherboard manufacturers website and download the latest bios, that's
if they have one.....
