I think that the problem may be with smartdrv.  I used to use it as my
caching routine, including outside of windows.  With the smartdrv
version for Windows 3, my AT switches into Turbo mode whenever
extended memory is accessed (such as when the disc cache is used).
This switch isn't so bad in itself, but it indicates to me that the
program counter is dancing around in the BIOS out of control.  I have
stopped using smartdrv for this reason.
