 That is incorrect, you CAN share IRQs on the ISA bus, and ive
 dealt with that nightmarish setup  in my previous work 5 years ago,
 Most of the Dialogic telephony cards and drivers make extensive use
 of IRQ sharing, shared memory and some very disgusting settings
 for they intercard communications across a PCM Bus used to be
 called (PEB) and now replaced with the new SCSA technology,
 blah perhaps not new anymore i have not touch one of those
 in years.

 Anyway, for the ISA IRQ sharing fanatics, forget it, unless
 the drivers and cards were thought and implemented to
 support it you are just asking for trouble.

 any, this is OT i guess, i shut up now..
