thats exactly whats happening when you specify a pirq= line. That should
be considered a 'high prio override of higher nature' ;) Btw, does your
box still work with 2.1.84+enabler#1+pirq?

the 'prefered' way is to find some mechanizm to figure out the pirq
settings for your board automagically. This means you'll have to basically
somehow figure out which physical PCI slot does what ISA IRQ. Does anyone
know how to access the PCI chipset PCI->ISA IRQ redirection table
registers [or however they are called]? I have a Neptune chipset and no
such problems.
