Syslinux - Oct 2007 - Passing commands from pxelinux to gpxe ?

Hi All,
Sorry if this is a stupid question, but I've managed to get
pxelinux to load gpxe and then manually load linux by
using the gpxe command line and HTTP for the kernel and
initial ram disk.

My question is whether it is possible to somehow pass
gpxe commands through some mechanism other than
the DHCP filename response. Since I don't have control
over our DHCP infrastructure, but do have control over
pxelinux, I'd like to some how tell gpxe what to do next
without having to rely on the DHCP filename response.

Apologies if this is off topic.

Doug

It's not, but the answer, unfortunately, is negative.

There 3.60-pre* development branch of syslinux can be run on top of gPXE 
(I think a development branch is needed there, too) to use full gPXE 
capabilities from inside syslinux.  It still has some rough edges, but 
it does work.
