Question : Problem: 304 keyboard or system error

I have a new key board but gant get rid of the old PS2 port one as each time i reboot without it i get the 304 keyboard or system error and my compaq 510 cmt will not start up. I have not been able to enter into the bios to be able to turn off the error messages as the bios menu i get to does not have this option. Can anyone help.

Answer : Problem: 304 keyboard or system error

This indeed used to be the case with old Compaq's (PIII models): there was no BIOS setting to disable keyboard warning, so a PS/2 keyboard had to be present.

Shame on them if that is still the case with their P4 models...

If there is really no way around it, you could keep the old keyboard plugged in, but leave it behind your pc and work with the new usb keyboard instead...
