The support for 3com NICs got me thinking about other NICs with boot ROMs.
I've got a few intel 100 pro PCI cards around, with the 82558 chipset. They have a PLCC socket, and a parallel interface; so they *should* support any PLCC 28/29 family chips. There's good documentation available, so I think adding support should not be too difficult.
The only problem is, 82558 only supports up to 64kB [A0:16], and 82559 only supports up to 128kB [A0:17]. So I'm not sure if I should bother, especially with the PLCC socket, and the fact that we already have support for the cheap and common 3com cards.
If you guys think it would be worthwhile to support, I can take a stab at it though. :-)

I'll take a look into some of intel's other ethernet controller chips, see if anything supports > 1Mbit. Although I have a suspicion that more modern controllers probably moved away from the parallel bus and/or dumped boot rom altogether. And of course - I'll have to make sure someone sold a physical card with them and a ROM socket!

Hi Marko,
I had lots of interest in the intel nics a while back while doing netboot/etherboot stuff, you may peek into the contrib folder in the etherboot(gpxe?) sources. maybe you'll find the notes there useful. most of the tools are dos based but maybe you'll still find something to pick your brains.
