Hello, I'am new here, but I hope to get some answers
for these simple questions ( simple if you have the documents).
As you know, IBM has the great knowledge to hide all information
on there computers (if you want to pay a lot of money you can get
reference manuals, there stands a little bit more as in the user 
manuals telling nothing with lot of words. Afer having read about 
fifty books on PC's, it seems I have broken trough that wall of 
pseudo-protection of IBM. But some questions are still open:

1. How do I program the so-called intelligent keyboard of an AT ?
There is a rumor You can switch back into real mode with a shutdown
value in the RTC and programming the keyboard.

2. Could anybody give me the full (!!) declarations of the microsoft
mouse interrupt 0x33 functions (not only function 0,1 and two, there 
are much more) perhaps in C ?

3. Where is the location of the video-card and ROM in protected mode?
Does the video-card base remain on its physical real mode adress, or
is it swapped hard-wired to a higher adress like the ROM should do 
(if IBM did not change that automatic switching of the iAPX286/386/486
on initialization) ?
