PS2 mouse installation - making it permanent

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

I have a brand new Sony RA304. It has a HID compliant wireless mouse which is
installed on the BIOS and works well. I want to install a PS2 mouse in
addition to the wireless mouse. It detects the PS2 mouse sometimes, but not
always. The device manager shows a PS2 mouse sometimes, but not always. When
it shows a PS2 mouse, most of the settings are GREYED OUT. So i cannot change
them.
Unlike my previous pc, the BIOS does not show any options to enable PS2
mouse support. Which makes me think that it is set as default to AUTO. In the
previous pc, changing BIOS setteing from AUTO to ENABLED used to solve the
problem.
How do I get around this? How do I make it permanent? I am happy to enable
services or go into msconfig if that helps. I know that it may delay the
actual startup of the mouse function.

Please help!!
