The BIOS (pcfg) boot config writes the kernel BOOTIF as `${netX/machyp}`, a
legacy gPXE spelling, while the UEFI (ucfg) config for the same node already
uses the iPXE-native `${netX/mac:hexhyp}`. xNBA is built from iPXE, whose
documented format is `mac:hexhyp`.
This is a consistency / standards-compliance alignment, not a fix for broken
behaviour: the shipped xNBA still honours the old `machyp` alias -- confirmed
by a real legacy-BIOS PXE boot, which came up fine with the stock spelling.
The change brings the BIOS path in line with the UEFI path and the documented
iPXE syntax, so both paths use one form and neither relies on a deprecated
gPXE alias.
Validated on a throwaway EL9 xCAT cluster: a legacy-BIOS client PXE-booted
with the patched config and genesis came up.
Recovered from the unmerged lenovobuild branch (original 85ce5b7e).
