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.
