We were relying on the original PXE UNDI (broadcom?) and chaining with kkpxe - w/o set use-cached 1 and the dhcp net0 was failing. > If the DHCP transaction is your only point of failure, you may use: > > set use-cached 1 > dhcp net0 > > within your embedded script, which will take the IP parameters from the > same DHCP transaction which send gPXE to the client. We added DEBUG=dhcp to the build and set use-cached 1 in the script before dhcp net0 (kept the discovered network info) and the network just didn't work - ifstat would show TX but no RX. w/o set use-cached 1 the dhcp net0 on the console always timed out w/o any real debug info - just showed it trying 4 times instead of the failure alone. Finally, I built and loaded undionly.kpxe instead. Found out you can't use set use-cached 1 with that gpxe image (duh - makes sense as the kkpxe "keeps" the former env when loading and 'kpxe' doesn't - fuzzy on understanding, but i get the idea.) This works. Don't Understand why. Thank you for the suggestions. db
