Unable to boot Broadcom NetExtreme Gigabit NIC (BCM5761)

Question Unable to boot Broadcom NetExtreme Gigabit NIC (BCM5761)
Hi guys! My name is Anderson and I´m a new user of iPXE bootloader. I would appreciate some help with an issue that is occuring with some HP model clients. All my configuration with DHCP, iPXE embedded script and firmwares (kpxe/efi) seens to be fine with Lenovo/Dell clients, but is failing with my HP 6005 Pro SFF clients. I used the https://rom-o-matic.eu/ page to create both files using the option All Drivers enabled, but with the HP computers the boot process fails at the Configuring Net0 stage. I think that this issue may be occuring due to a missing driver for the Broadcom NetExtreme Gigabit NIC (BCM5761). The machine tries to communicate with the DHCP service and returns this error after several tries. If I configure a static IP address on my script the returned message is "No configuration methods succeeded". Can someone help me with this issue? Thank you.

snponly.efi and/or undionly.kpxe should work (they are generic and uses UNDI/SNP/NII drivers provided from firmware), if not you are likely to have firmware/BIOS bugs and should report it to HP
You can find standard images built for those at http://boot.ipxe.org

you should never have a "all drivers enabled" build with a .kpxe extension, (.kpxe should only be used with undionly)

Try to start iPXE, press ctrl-B at the first prompt which takes you into the iPXE shell.
here type
Code:
ifstat
dhcp
ifstat
then upload that eighter as text, or as a screenshot (the forum does not allow uploads, so post it elsewhere and then add a link to the image here)

A quick search for "iPXE BCM5761" finds http://lists.ipxe.org/pipermail/ipxe-dev...04476.html and also other links that shows that it is "supported" however we also do know that the tg3 driver which is involved, has a few issues, it is especially visible on iMacs which you can find a lengthy thread about in the forum.
