@sideone said in [BUG] iPXE Boot Loop & Menu Failure After FOG 1.5.10.1660 Upgrade:
Your suggestion of trying a realtek.efi didn’t work
At running the risk of polluting this thread just a tad more. If undionly.kpxe worked in bios mode then snp.efi should work in uefi mode.
Also knowing the exact realtek nic model could be important if its a 8168 (1GbE) or 8125 (2.5GbE) the default drivers in the linux kernel wont work well. You can try to use the experimental kernel that has the official realtek drivers built in https://github.com/rluzuriaga/fos/releases/tag/EXPERIMENTAL_REALTEK_DRIVERS Understand this will only help once you get past the FOG iPXE menu. This would be after undionly/snp has displayed the FOG Menu.
