We can't get the com ports to work. com1 and com2. We get a yellow ! mark under the port status (system, hardware, device mgr.)but there appears to be no interrupt conflict. It says this device is no longer functioning properly and may need to be replaced, contact the manufacturer. Location on Intel 82371ab/eb pci 2 isa bridge. Our motherboard is ASUS P2B 400Mhz and we got a message telling us to upgrade processor support on loading nt5. Perhaps it is a scsi card that is not working? We have a Jazz drive on an internal card that we can't identify.
