Something must be sitting on these addresses or IRQs 3 and 4, or they're trying some sort of Plug & Pray trickiness. Check your devices. I know that the Award BIOS is smarter than to make these things PnP configurable, I have it in my ASUS P55T2P4 board and the serial ports probe fine. > All extraneous cards have been pulled and the ports work > perfectly under MS-DOS 6.22. Scratch the busted board theory. You might try the 2.2-STABLE or 3.0-SNAP boot floppy, this may be some screwy UART that has support in a newer release.
