this isn't an answer to your question, but it's a very good idea to
set up your dhcpd.conf to have 'filename "gpxelinux.0";' rather than
'filename "pxelinux.0";'

it does everything that pxelinux.0 does and a lot more - including the
ability to retrieve images via http rather than tftp. much faster and,
IME, much more reliable.

for more info, see:

http://etherboot.org/wiki/index.php

and

http://syslinux.zytor.com/wiki/index.php/The_Syslinux_Project

BTW, gpxelinux.0 is in the syslinux-common package in /usr/lib/syslinux/



if you then define an apache alias like the following, you can have a
/var/lib/tftp/default like the one at the bottom of this message

    Alias /tftp/ "/var/lib/tftpboot/"
    <Directory "/var/lib/tftpboot/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
        Allow from your.local.network/mask
    </Directory>



that gives you a generic netboot menu which can run debian rescue images,
debian installer, and clonezilla.  and whatever else you need.

what root fs are you trying to load?  is it compiled into your
kernel or as a module in your initrd?   it looks like it isn't.
