Yes. My modem is on what I refer to as IRQ 2. In DOS programs,
I set the software to use IRQ 2 and everything works. If I use
"IRQ 9", nothing works.

In Windows 3.1/95 I have to set it to IRQ 9 or nothing works. In
Linux, I set it to IRQ 2 and it works.

PC hardware is braindamaged IMHO. It would be nice to see a new
architecture with a PIC with 256 IRQ's, all non-cascaded in one
chip. Same goes for DMA and any other resources.
