Debian live 5 and PXE

[mabrothrax <mabrothrax@orange.fr>]

Hello!

I would like to distribute the network an iso Debian live 5 environment
with PXE. The server contains tftpd32 win, Deamon Tool an HFS. Tftpd32
first provides an address via DHCP then gPXElinux.0. Everything works
correctly with utilities such as Memtest86 2.11, Seatool 2.13 and 1.10,
Gparted Live, Tor uclibc or PING 3.0.
Here is the folder tree (for Debian, from unarchived .iso) :

C:\PXE\
   \debian5\
       initrd1.img | vmlinuz1
   \menuconf\
       menudesign.conf | passwd
   \pxelinux.conf\
       default
   chain.c32
   gpxelinux.0
   memdisk
   tftpd32.exe
   menu.c32
   tftpd32.ini
   vesamenu.c32

And an extract from the file \pxelinux.conf\default :
(The best solution, the one with less problem)

DEFAULT vesamenu.c32
MENU INCLUDE menuconf/menudesign.conf
ALLOWOPTIONS 1
PROMPT 0
NOESCAPE 0
#TIMEOUT 3000

I understand that it can not work as well. I tried lots of solutions,
even using the cd's tree unpacked in local folder, nothing happens.
I also searched on the site debian.org the doc (which explain for an
install linux :: linux), in the file of the cd and tested many
combinations of  "cheat-codes," nothing was done.
Some supplementarys details :
I can install Linux on the server. It must stay under Win$...
Finally, the problem is the mounting of the root file system.
I try to since four days ago, spoken on irc and it's cause I'm now
requesting your help...

The questions are:
 - Would you help me ? Is this the right place to ask?
 - Is it possible in this configuration?
 - If not, what should I change?

In advance, many thanks for your time...
Regards.
