- Hi!
-
- I had the same problem about detecting which IRQ the mouse driver uses, and
- I came up with the following simple method: Check (from INT table at 0000:0000)
- what is the INT 33h handler's segment. Then check which IRQ handler is at
- the same segment. This is most likely the IRQ mouse driver uses.
-
- But of course, if INT 33h FUNC 24h is available, one should use it.
