I accidently flashed the wrong BIOS release to my motherboard, and rendered it "knackered" as a result (the BIOS did not support block-mode install so that I could flash back to a correct version). I sent it away to get repaired, and the people I used replaced the BIOS.

After setting it all up I found that my PS/2 mosue would not work. After establishing that it worked in another system, I tried a serial mouse, again with no luck, both in windows and DOS. Windows would not detect the PS/2 or serial mouse in any instance - each time it would report that no mouse was connected.

I then tried the external serial modem I use under windows, reported that the port was closed when I tried to interrogate the modem.

Whilst my motherboard was away for repair, I upgraded to an ATX case (from and AT one), but otherwise my system spec remains identical :

Commate S7AX Motherboard Ali5 Chipset
Award BIOS - release 2.7 (award v.4.51PG)
AMD K6/2 450
160 Mb RAM (128 PC133 SDRAM, 32Mb EDO)
Windows 98 SE

The only thing I can put it down to is a BIOS issue - the ports don't work under windows or dos. I don't know if the BIOS has somehow disabled these ports, but I am sure it is not an IRQ or conflict issue.

Any ideas anyone ??!!

I had a problem of a mouse not being detected and, like you, I tried everything until one day I substituted the mouse ribbon cable and blow me down it worked. The cable had apparently been damaged somehow.
Hope your problem is this simple. Let me know if it works.
