- Rule 1: Never trust MSD or any other "diagnostic" tool. This cost me at
- least three weeks installing my modem/sound card.
-
- Rule 2: Interrupts do not like to be shared on ISA. The default interrupts
- for Com 2 and 4 are IRQ3. Only one will like to be there. Actually, if both
- are there, neither will work.
-
- Also Com1 and three share a default interrupt. Not a good thing in practice.
