iPXE fails to boot anything

[AyrA]

I switched from regular PXE to iPXE in the hope the Images required to download from the boot server via HTTP load quicker than with TFTP (and yes they do). I managed to set up a windows DHCP Server the correct way to get iPXE running and downloading the folowing menu script from my HTTP Server:

Code:

#!ipxe

######## MAIN MENU ###################
:start
menu Welcome to iPXE's Boot Menu
item
item pmagic     Parted Magic
item memtest    memtest86+
item regedit    NT Password and Regixtry Editor
item atih       Acronis True Image Home
item
#item shell      Enter iPXE shell
item reboot     Reboot
item
item exit       Exit (boot local disk)
choose --default pmagic --timeout 60000 target && goto ${target}

## Utility menu items:
:shell
echo Type exit to get the back to the menu
shell
set menu-timeout 0
goto start

:failed
echo Booting failed, dropping to shell
goto shell

:reboot
reboot

:exit
exit

I get lots of Problems because I cant boot anything. Selecting an option from the menu will load the kernel and the image but various things happen:
Parted Magic (linux kernel)
It boots for a short while and ends up in a kernel panic (Caps Lock and Scroll Lock blink rapidly) The Message is too long to read on the screen.
memtest (Floppy Image)
Ths Image loads and displays the memtest version selection screen. Selecting any version locks up the system just after start of specified Version
NT Password and Registry Editor (iso)
stops booting after the Message
Loading Boot sector... booting...
Acronis true Image Home (iso)
Same as the Password reset tool.

Since everything fails I am assuming I am doing something completely wrong. Using the classic method (PXE Linux and menu.c32) all these Options are working but again are limited to a TFTP Server. So far I would be happy if at least Parted Magic would boot. I verified that I am using the newest Version of provided tools and images.
