SYMPTOMS
You may receive the following error message on a blue screen while Windows 98 Second Edition is starting:

An Exception 0D has occurred at VXD VMM(0H)+00005B01 0028:C0006B01

Note that this behavior occurs only on double-byte character set (DBCS) versions of Windows 98 Second Edition (this includes language versions such as Chinese [both Simplified and Traditional], Japanese [including the NEC platform], and Korean).



CAUSE
AMD K6-2 350MHz and faster processors that have a CPU ID of 0x58c (Family 5, Model 8, Stepping C) are sensitive to a particular string of instructions in the DBCS Vmm.vxd virtual device driver for Windows 98 Second Edition. This condition occurs only on a very small percentage of computers with this hardware and software combination.
