Which bootblocks? sys/i386/boot/biosboot? Or sys/boot/i386/boot2?
sys/i386/boot/biosboot is not even in -current.
sys/boot/i386/boot2 does both a.out and elf.
IMHO, if Whistle are going to go out on a limb with a 5.x release with old
bootblocks that are no longer in the tree, I'm sure they can figure out how
to change "btxld -f elf" back to "btxld -f aout".
I tried this about two weeks ago, on old bootblocks (pre-4.x) and at the
boot prompt, "wd(0,a)/boot/loader" was rewarded with "Invalid kernel".
Installing /boot/boot2 solved it. I dont know which 2.x bootblocks they
were, but they were *not* happy.
3.x and beyond shipped with a.out+elf aware bootblocks.
