I'm using the 509b with no difficulty whatsoever. I think it's
circulated around the list a lot lately but I'll indulge anyway:
1) You must have a BIOS that permits you to set an IRQ to an ISA device
(make that IRQ unavailable to the PCI bus)
2) Boot DOS, use the 3c5x9.exe on the 3com floppy to turn off chug
and pray in the card's prom
3) Set the base memory and IRQ in the 3509b prom
In my case I set it on IRQ 12 at 0x280 (i.e. IRQ 12 is reserved for an ISA
device in the BIOS) -- I compiled it into the kernel but it can also
be set by booting with -c -- my entry in the kernel config looks
like:
device ep0 at isa? port 0x280 net irq 12 vector epintr
Compile the kernel with that and bingo: good to go!
