Windows NT has no GUI for setting up a PC-CARD's IRQ. You must edit the registry and enter an IRQ mask. Edit:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Pcmcia
Add Value name InterruptMask of type REG_DWORD and set the RADIX to Binary. Enter the 16 digit mask.
The InterruptMask is composed of a series of binary switches,
0 means the IRQ is available and 1 means the IRQ is unavailable.
Here is an example for allowing IRQs 10, 9, and 3:
| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | 1 | 1 | 1 | 1 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 0 | 1 | 1 | 1 |
When you click Ok, the mask would appear as f9f7 in
the right hand pane. Exit regedt32 and reboot.
