I don't think there is a way to save this MB for use with a keyboard. You 
could load a different OS by installing a pre-configured OS hard drive and 
accessing the system via network/serial terminal, but without the local 
keyboard, it is toast (IMHO).

I took a look at the manual for the MB, and there is no conclusive statement 
that the MB would support USB mouse/keyboard that I could find, no serial 
console redirect, and no way to modify the BIOS settings to even try a USB 
keyboard. You could bot off a DOS diskette with a startup .bat file that 
would redirect input to come from the serial port, but even with a DOS system 
there is no tool t update the BIOS.

I think it's time to swap out the MB and upgrade they system (hey, want a 
SuperMicro MB with dual PIII/450 CPUs?). I don't see any guarantee that any 
efforts will result in a functioning system with a local keyboard...
