I have built a 80-486 DX2 66 SL computer. I was missing some parts for it for a long time, and finally got hold of those a few days ago. I decided to redo the entire project from the bottom. So before I took it apart, the mouse worked. It was Microsoft Mouse which has a PS/2 port with a DB9 converter in the package. It uses IntelliMouse software and drivers.
Now however, after rebuilding, I cannot make the computer detect the mouse at all, and I haven't move any jumpers on any expansion-cards or motherboard. The mouse was connected to serial-port COM1 before I took it part. It worked with both DOS and Windows 3.11. The COM1-port is located on an I/O card that has two IDE-channels, a floppy-drive channel, a game-port, parallel-port and another serial-port. It is a ISA Vesa Local Bus-card which have been working nicely.
So here is what I've tried:
- Moved the current I/O-card to the other two available VLB-slots
- Tried another I/O-card which is VLB
- Tried another I/O-card which is ISA
- Tried another mouse which is serial
- Tried to remove everything but the video card and the I/O-controller
- Tried connecting just one hard drive and one floppy drive
- Made sure the mouse is working on a different computer
I don't know if I listed all the things I've tried, but these are those I remember at the moment.
I really hope someone can help me get to the bottom of this!!!
