Yesterday I went ahead and installed Windows 98 on a machine built around my newly acquired Asus P5A. BIOS version is 1011.005 (Beta).
During setup I recognized that the PS/2 mouse was not working but I wasn't too worried and used the keyboard to navigate the setup.
But even after the installation was finished, Windows wasn't able to detect the PS/2 mouse.
There's a BIOS setting called "PS/2 Mouse Function Control". Here's the excerpt from the manual:
PS/2 Mouse Function Control (Auto)
The setting of Auto allows the system to detect a PS/2 Mouse on bootup.
If detected, IRQ12 will be used for the PS/2 Mouse. If not detected, IRQ12
will be reserved for expansion cards. Enabled will reserve IRQ12 for the
When setting it to Auto, Windows won't recognize the PS/2 port at all. Setting it to Enabled makes Windows detect the port as a new device, but it will show as not working in the device manager. Removing and re-installing the device in the device manager won't help.
So I took a DOS boot floppy with CuteMouse to try something different, but to no avail.
There is no visible damage to the PCB around the PS/2 ports or to the connectors.
I'd rather avoid using the machine with a serial mouse (which is detected by CuteMouse without issues), so any help would be appreciated.
