Problem(s) this Update Resolves:
================================

Systems using the Cyrix 5520 companion chipset to the MediaGX integrated CPU
running at 233MHz and greater may yield a 'Divide by Zero' error, which
originates in NDIS.VXD. Note that this problem is not limited to the noted
chipset; The Cyrix 5510, and many other clock IC's are also susceptible.

While performing internal timing calibration, NDIS.VXD may attempt to divide
a zero value under the above noted conditions, resulting in the error. This
problem is caused by a vulnerability to errors under high clock speed
conditions that exist in both the timer latch hardware as well
as the NDIS.VXD component.
