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 ??!!

David,
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.
Rob
