I should've mentioned I am using FreeBSD-current which has
a working pxeboot thanks to jhb.  It netboots with my
patched
etherboot bios but fails with bioses distributed with qemu.
My year old patch works around etherboot's length related
bug -- a TFTP data mode packet with length=0 confuses
qemu's
roms.  I just realized we can make a fix elsewhere to
make the stock qemu bios work!  It is a complicated fix so
be prepared to really understand it.  Ready?

Here is how:

    echo >> $tftproot/boot/pxebot


The default NE2000 NIC works fine too but you may want to
use
rtl8139 for better performance.
