So I've been fighting an old EPOX P55-TV board with a P133 and 32MB to get a serial mouse working in DOS however I have been unable to. I have tried two different 2x10 serial IDC headers but to no avail. I have checked the BIOS at least a dozen times, I have attempted it on every setting offered including "auto", I have tried COM2 and have even attempted to connect a ps/2 1x6 IDC header to the 1x5 that is on the board but no luck. A few weeks ago I thought I would attempt to try this in Linux just to see if I was crazy as I have built a lot of these systems and never seen this before. Initially I tried it with a MS serial mouse and the same thing happened but then I decided to disconnect the MS mouse and connect an optical serial mouse just for fun and it began working! I switched back to the MS mouse and it stopped working (and yes I have verified the MS mouse works on other systems that do not have this problem). So what exactly does this mean? I then installed Win95 on this host and tried the same thing and regardless of which mouse I used it did not work. If it worked in Linux (and a really old version of Linux at that) but refuses to in either DOS/Win95 then it can't be the board (can it?)
Anyone with any ideas as to what to try I would welcome them as I do not know what else to try.
Thanks!
