As far as I know, the PS/2-machines are quite upward compatible to the
IBM AT in their structure, but far more flexible (and software-programmable).
For getting information about the interrupts and the io-ports, you should
look in the "Personal System /2 model 55 technical reference" and the 
"Personal System /2 bios reference manual". There are a lot of other book
around, but I use these two quite often.
