Re: 486 PC. Keyboard problem.
Hi Graham,
are you using the original boot disk to start the pc?
Reason for querying is generally serial ports are configured by the CONFIG.SYS and AUTOEXEC,.BAT files during booting.
Additionally there might be dip switches or hard wired selections on the Controller Card (which you changed) involved. If so, are they the same on both original and replacement cards?
Regards - Mike
