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.
