SYMPTOMS
If you are debugging your PS/2 device and watching INT 15h calls, you may
see some odd function calls generated by VMOUSE. You might be looking for
standard mouse calls matching AX=0C2xx, for example. During default PS/2
mouse initialization you might see the following INT 15h calls just before
the standard initialization:
with AX = 0F963h
with AX = 0F95Fh
CAUSE
These are used internally by the operating system. The first one always
occurs. These do not affect normal PS/2 devices and can be ignored.
STATUS
This behavior is by design.
