But the question is, why did it work just fine with 3.80 and not with 3.81??
The BIOS is the latest version for this motherboard as I just confirmed with 
the MSI web site.
American Megatrends Inc.
V3.A
09/29/2004
as reported by HDT.

I've used various versions of isolinux on these machines for years, and only 
with the 3.81 did the error occur??
