A FreeBSD ISO does not boot via a USB CD-ROM for Supermicro (and other?)
motherboards that use Intel CPUs.  

Sure this is an old problem...
 http://docs.freebsd.org/cgi/getmsg.cgi?fetch=78298+0+archive/2007/freebsd-stable/20070128.freebsd-stable

 http://lists.freebsd.org/pipermail/freebsd-qa/2006-September/000783.html

Sure would be nice if someone could fix the 'real mode' 'vm86' problem
that plagues FreeBSD install disks but no other OS.  I am offering a $50
bounty to be paid to http://www.freebsd.org/donations/ if the standard ISO
for FreeBSD 7.0-RELEASE addresses this problem.  In other words, if I can
download the ISO, burn it to disk, and boot it off a a USB CD-ROM onto
Supermicro hardware.
>How-To-Repeat:

Download the ISO for 7.0-BETA4
Check checksum  :)
Burn to disk
attempt to boot disk on USB-CDROM drive attached to a Supermicro Motherboard
 (eg the PDSML or PDSMi)


>Fix:
The only acceptable fix would be a new, working ISO on ftp.freebsd.org.

 Seems that Konstantin (kib@) already had a patch that you can try.
