iPXE Chooses Wrong Nework Interface

[robinsmidsrod]

Have you verified that indeed only net0 is being initialized and not net1 as well? ifstat net0 and ifstat net1 should tell you if they're both configured. 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?
