Recently i was playing Monkey Island II in my msdos machine, using an AT keyboard + PS/2 optical mouse in pure MS-DOS, and suddently my dog tripped on the mouse cord, and it fell of the table.
The game kept playing with sound, but the controls were halted. So, i turned it off the machine then back on. After that, the mouse stopped working for good.
I have made some basic troubleshooting, but with no success:
- Checked if there was a connection break between the external PS/2 port pins to the motherboard 5-pin JST connetor - no issues, it was OK.
- Checked the voltage from the PS/2 port when the motherboard was ON (without the mouse connected) - seens fine giving +5v, so i think it´s OK.
- Tried to connect the mouse to another computer, and it worked fine!
- Tried connecting a PS/2 keyboard to the PS/2 port, same simptons of the mouse.
The simptons are:
Mouse turns on, flashes optical sensor for a few seconds, and then turns off (in the memory check screen of the bios). It is not detected under dos or windows.
PS/2 keyboard same situation, flashes two times (status lights) then stops. Bios says keyboard not found. To be honest, i have never tested a keyboard in this port before (i use an AT keyboard), i´m not sure if it worked before!
Specs are:
- Motherboard Full Yes 82430IB REV A (Intel 430fx - http://www.elhvb.com/mboards/fullyes/)
- Pentium 100mhz
- 16 MB RAM
What could be the issue?
Thanks
