Otherwise, it looks like you need a new system board... It looks like a problem with the Super I/O controller which handles USB, RS-232, Parallel, Floppy and CDRom. It might be the RS-232 interface chip (something like MAX3232). It's not uncommon for these devices to get blown by ESD. Also, the charge pumps sometimes fail, or don't start reliably. Possibly, a PC serial card would work if the machine will boot. Dave -- J.
