Baremetal servers' BMCs are a bit sad, we can probably afford to use https://github.com/samozy/iusb if we rewrite it properly and internalize it in our process or we may need to consider iPXE / netbooting.

Otherwise, reimaging may require manual intervention.

Option: Burn iPXE on the network card permanently.

Network cards are:

06:00.0 Ethernet controller [0200]: Intel Corporation I350 Gigabit Network Connection [8086:1521] (rev 01)
06:00.1 Ethernet controller [0200]: Intel Corporation I350 Gigabit Network Connection [8086:1521] (rev 01)

80861521.rom is an OptionROM that iPXE can generate for those cards which we can flash via BootUtil.exe via DOSBoot: https://ipxe.org/howto/romburning/intel.

The BootUtil is also available as EFI64 executable which is easier for us since we don't have a way to boot an floppy image for now.

However the utility says (on builder-10):

FLASH not present

iusb-spoof has been rewritten in rust and deployed on wob-vpn-gw. Booting off "UEFI: Virtual Floppy" will load the latest config out of the appropriate hydra job.
