Is there any progress in fixing FreeBSD bootloader to be able to boot
from USB devices? Any patches available which can I test?
Or are there any possible workaround to make FreeBSD bootable from USB
flashdrive in any machine? (I can boot from USB flashdrive and USB
DVD-RW on my home PC and notebook, but can not boot HP DL140 and Sun
Fire X2100 servers ;[)
