- Do not export (for the PIC/PIT/Speaker) the port functions but use instead the common port interface.
- In bios.c : IOWriteB(PIC_MASTER_DATA, PIC_ICW4_8086 /* | PIC_ICW4_AEOI */); (line 377) : in NXVM they add PIC_ICW4_AEOI; [TheFlash], can you have a look at this and see whether it is required for the master PIC only, otherwise remove this comment.
