However, there is a difference between ethersel.c32 and nictype.c32,
which can be very important in some cases: ethersel.c32 uses IDs of
all PCI devices in the machine (not even just network cards - I used
it to detect SATA and RAID controllers), while nictype.c32 uses the ID
of just a single network card which is actually used for PXE booting.
If the PCI ID is used to decide what kind of broken PXE workaround
should be used, and the machine has several different network cards,
ethersel.c32 may give wrong results.
