Actually that is untrue. There are four INT# lines on a PCI bus. *everything* uses INTA# and relies on the chipset and motherboard to correctly "wire" it up so they don't share... I was going to ask Digium if they could bring all four INT# lines into the FPGA and allow me to select which INT# to use, it'd sure give a HELL of a better chance at finding a free IRQ, wouldn't it? Especially for those goddamned motherboards that DON'T "cascade" the INT# lines... IIRC it's SUPPOSED to be wired INTA -> INTB -> INTC -> INTD -> chipset_INTx INTB -> INTC -> INTD -> INTA -> chipset_INTy INTC -> INTD -> INTA -> INTB -> chipset_INTz etc... at least on older systems... It's been a while and I've always wondered why card manufacturers don't allow me to use INTB/C/D if I want/need to. Sure it's extra complexity but jeez man, it's "only" software. :-) -A. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
