We have been network booting FreeBSD for some time with pxeboot. So I am

got the idea somewhere that gpxelinux could do that for us. We copied
gpxelinux.0 from the syslinux-4.02 distribution and replaced pxeboot with
"gpxelinux" in the dhcpd.conf file. Indeed with a configuration file in
pxelinux.cfg like this:
default freebsd
label freebsd
PXE pxeboot
and the root path still specified as a DHCP option, FreeBSD 8.1 does boot.
If I replace the first line with:
UI menu.c32
the client does display the menu and but if one hits return to select the
single item offered the client merely hangs for a minute, then announces
"boot failure". I am guessing that once the UI is interposed, somehow the
root path isn't getting transmitted to pxeboot.
4.01 works, both with menu.c32 and vesamenu.c32. I can't say I've
experimented much farther, but used it when writing this:
http://www.wonkity.com/~wblock/docs/html/pxe.html
All the other gpxelinux boot kernels seem to expect the information about
the root filesystem to be specified in the pxelinux.cfg file, rather than
in dhcpd.conf.
FreeBSD's pxeboot isn't as versatile as others.
Does anyone have experience with this? FreeBSD isn't mentioned anywhere I
can find in the syslinux or gpxelinux documentation, and the various web
posting I have found linking FreeBSD to gpxelinux are all about do
installations of iso files over the net.
Yes, that's one of the reasons I wrote the article above.
We finally got the thing working - by simply dropping gpxelinux and using
pxelinux instead.
