- No. The processor has a separate NMI pin, NMI is NOT an IRQ line.
- I think, it is _impossible_ to install an NMI handler without writing a VxD or
- an NT kernel mode driver. On the other hand, it is _easy_ to trap NMI writing
- a VxD, because the system offers an API for doing this. See the VxD newsgroup.
