Hello!

I'm currently doing some work on an IBM PS/2 model 55, and I need some info;

1. How do I get an IO-port and an interrupt-channel on PS/2s. I need a rather
   technical explanation, because I have to code that part. (Isn't the MCA in-
   -volved in some way??)

2. What interrupt-controllers do you have on an PS/2? Is it the same structure
   that the old AT has (no, how strange?) with a master PIC and a slave PIC?
   Is it the MCA that selects IRQ-channel or is it some other interface?

3. If this is the wrong newsgroup, where should I post this kind of questions?


I've been looking all over our library, but I can't find anything at all...
Should I look in some particular book, paper etc etc...

Thanks a lot in advance,
