I've got a new 4-port TULIP card, but it only partially works.  It
smells to me like an IRQ problem:  Of the four ports, one is getting
its own IRQ, and the other three are sharing IRQs with other devices.
The first port (de0) works, and none of the others do.  Is there
something wrong with my BIOS, and the way it's assigning IRQs?  Do I
have too many devices in my computer?  Is this a NetBSD PCI bug?  Are
PCI devices even allowed to share IRQs with each other?  etc.

The docs that came with the card said I needed to make sure that that
PCI slot was set to use "INT A", whatever that means.  I saw nothing
in my BIOS setup utility (Award Modular BIOS) that looked like it
would do this.

Thanks in advance for any information, and please respond to me via
email, since I don't read this list.  See below for dmesg output.
