[gPXE] Problems with gPXE, UNDI and VirtualBox

[Lars Kellogg-Stedman]

Howdy,

Is anyone else experiencing problems with gPXE's UNDI driver under
VirtualBox?  If I boot with undionly.kpxe, gPXE simply reports, "No
more network devices".  If I boot with the full gpxe.kpxe, then of
course it uses the native driver and everything works great.  pxelinux
is able to utilize the UNDI driver just fine.  If it helps, here's a
screenshot of gPXE booting:

I'm not really sure where to start debugging this problem.  Specific
help for this problem is great, but even pointers to general
information about debugging gPXE would be helpful, too.  Thanks!
