Well - I only have one hard disk, so in the end, I went through my bits box, found another ISA card, set it to ttyS2, IRQ15 (disabled secondary IDE in bios) - this seems to have worked... Only problem is, seems one of the UART chips is missing (unless one 16550 can handle two ports) as there's an empty socket on the board - a shame as this card is really easy to config for heaps of different IO/IRQ combos. Covers current need for three com ports, but might need one more.. Where could I find info on hacking other cards to use different IRQ/IO combos through physical alteration?
