iPXE Chooses Wrong Nework Interface

You can replace the built-in script to do dhcp net0 followed by dhcp net1, but this shouldn't be required, as far as I know. Is a DHCP server running on both networks?

Which driver is the 5708s driven by? If it is the tg3, then that one is old (unless mcb30 has committed the new tg3 driver) and doesn't run very well (very slow). The other driver for broadcom cards (can't remember the name) I know nothing about.

Have you tried using the latest vendor PXE ROM and using chainloaded undionly.kpxe to drive it, or does that not work for your setup?

Yes, I have verified that net0 is the only card initialized - if I drop to the command line and attempt commands like "dhcp net1" I get errors that the card does not exist.

And, yes, if I chainload iPXE, it seems to work fine, so I can go that route, for now, but I may have a situation, soon, where I need to boot from a network that does not have a DHCP server, so I'd much rather have a working one burned into the cards.

After posting this message I went back and did even more digging, and I think I found out what at least one of the problems is. This particular chipset uses the bnx2 driver, which still uses the legacy etherboot API (there's even a warning at boot time about it). I seem to remember there being some issues with that API that caused some of these problems.

I know this is more a question for the developers list/forum, but I'll ask, anyway - what are the key differences in a driver between the two APIs - that is, if I were to look into switching the bnx2 driver away from the legacy API, what would need to change?

Thanks - Nick
