-
- Just a point to you all. Due to the utter rubbish that the PC motherboard
- must conform to (you know, the IBM original :-)) It is forced to act like
- an original AT.
-
- AT architecture has a problem with the interrupt hardware (a conflict
- somewhere but I cannot remember the specifics) and the hardware automatically
- takes interrupt 2, and cascades it so that it is now in the SECOND interrupt
- controller. This 'cascading' of interrupts is done mostly invisibly, but
- you must remember that interrupts on a pc go
- 1 9 3 4 5 6 7 8.
- Then you directly program the second controller.
-
- Its stupid, but its backward compatible with the XT (as if anybody cares!)
