Here's a weird one (kinda OT)

I have a 3Com 3C509B-TPO (16-bit network adapter) in a 486 PC running in
DOS 6.22. All the drivers are loaded and working and I can connect up to
my Win2000 box and mount its volumes locally. All good.

But when I try to transfer large files the DOS system invariably locks up.
I have to do a cold boot. I played around with the BIOS, disabling one
feature at a time until I found the culprit. Once I disabled the Internal
CPU cache then things worked fine.

So my question is, why?

3Com's 3C509B FAQ didn't address this issue and I couldn't find anything
from Google.

I don't expect an answer really. This is one of those problems that only
occurs to one unlucky person somewhere in the world at the worst possible
moment. Fortunately I can move files but it would be nice to know what
might be the problem if there is a solution.
