When I plugged my Promise TX2 card into my rig.. it took my IRQ15, so I colud only have the slave/master config of the onboard ide port(IRQ14). But I can have master/slave twice from the Promise controller(IRQ15).
But what i wanna know is how does the Promise card support two master/slave configurations while only using IRQ15!..
But I guess as long as it works I shouldnt question how or why!!!!!!
