The stepping code includes a letter, which is important.  It will be B
or C.  But the numbers are higher than any stepping code that has the
dreaded 32 MB aliasing bug.

And it may work.  This doesn't help much.

I had a few problems when I upgraded to a K6/233:

1.  The voltage.  Most K6s need 2.8V core voltage, but the K6/233
    needs 3.2 or 3.3 V, depending on the chip.  It's written on the
    chip.

2.  Overheating.  This applies particularly to the /233, which
    generates about 30W.  I did some investigation with a thermometer,
    and found that the temperature rises sharply with increasing CPU
    load.  Use only the original K6 cooler.

Obviously your problem isn't (2), since it doesn't get far enough to
overheat, and it always stops in the same place.  Check the voltage,
and play around with it if you're in doubt.  If that doesn't work, try
lowering the frequency, and check your motherboard/BIOS settings.
