- Hello.
-
- Since Linux is (fortunately) running under protected mode, I have
- some difficulties determining how to use my MPU-401 MIDI interface.
- Under DOS, i would redirect IRQ 3 (or 9, or .. have forgot the
- number) to an interrupt routine of my own.
- Well, I can get my program work without this IRQ help, but I also
- need access to port 330h and 331h. In DOS, a simple IO instuction
- would be sufficient, but in Linux, I guess that I have to tell the
- kernel to do this.
-
- BTW: The program is in GCC.
-
- Thanks for any help.
