Yes it is possible, but you need to patch sys/i386/i386/autoconf.c. included
in this message. I've only tested in the case of netbooting so I could
broken normal booting.
Then use Etherboot. I also included it an uuencoded update to the
etherboot port for etherboot-2.4.10 which can boot a FreeBSD ELF kenel.
This all works as of -current (yesterday). Sorry it takes so long
for the port to get updated and the Linux guys keep working on Etherboot
(which BTW they has code to boot FreeBSD now and they test it). Then I
have to wait for someone to read the pr's that I send in. They when someone
finally looks at it. It is already obsolete. Same thing with my sdcc
port that needs updating.
I expect Mike will kill me for this, but it works and I don't have a PXE
rom in this machine. I prefer a netboot panic rather then panic'ing my
laptop when testing things.
