I have just tried installing a Safecom LAN card in an Intel pentium III 550mhz computer but it doesn't seem to be connecting to the computer, ie. as if it's not plugged in to the slot.
The only other PCI card in the computer is a graphics card and that works in all slots. I also tried an old 10mbps card in it and that worked fine. I have tried the new card in another computer to check it and it recognised it no problem, so it's not the card that's faulty. I'm afraid I don't know what motherboard it is.
Anyone got any ideas what it might be?
