I think I put it together more because I can... and I wanted another PIO
ethernet device to compare against the existing NE2000 device. And I
couldn't see a reasonable way to implement 3Com's Legacy discovery mode.

I think the next thing I will put together is a 3Com 3C905C PCI NIC...
because it is supported by Darwin x86...

I have found a valuable resource for datasheets ...

Hopefully of use to anyone else who wants to simulate some hardware.

It is tempting for me to extend the AMD PCNet implementation to include
the SCSI HBA ... but then the problem would be sourcing a ROM image for
the device.

Which reminds me of one of my feature requests - a uniform way to load
ROM images, where - for example - a card may have an associated ROM for
net-booting etc... (and does the current BIOS support adaptor ROMs? I
haven't looked at its code in depth yet.)
