Hi Michael:

Well, what's trying to use it is the FreeCOM VOL command!
(Or something else in FreeCOM).  I doubt that there are
any explicit calls to VDS functions there.  The kernel may
be more likely.

This appears to be the same bug that caused FDISK to
wipe out the MBR, so it at least appears that just initializing
the VDS functions is trashing something in memory.

I could ship you this laptop if you believe that will help or
I can run any test routines you can think of!
