Here's some more info for anyone who can help me try to figure out why I can't get this NIC to work in this NAM. (I have a 4.04a copper NAM). The monitor and keyboard package are up and working fine. There aren't any dip switches in my NAM. There are 8 card slots and the first slot is not a full ISA slot. I have tried removing the IBM parallel port driver in MPTS but the NAM reboots itself continually w/o this driver until it is re-installed. I have a 3COM ISA 3C509B NIC card. When the NIC card is configured for IRQ 9 the NAM locks up. trying to access any feature code from the phone results in an "inactive feature" display. The mouse moves on the desktop of the NAM but won't open anything. When an RMVIEW is done to display resources on the NAM nothing is using IRQ 9 but IRQ 2 says "PCI pin = none flag = exclusive PIC_1". I know that in newer OS2 machines IRQ 2 and IRQ 9 are linked but I don't know if the use of IRQ 2 in this machine has anything to do with the problem. Any help would be appreciated.
