Wimboot - Could not boot image: Exec format error

[Logan]

I am trying to network-boot a system via HTTP from a server that has IIS version 10 by following the steps in http://ipxe.org/appnote/uefihttp. I am using the latest ipxe.efi. To avoid infinite loop due to ipxe.efi being downloaded on every DHCP request, I followed the instructions in http://ipxe.org/howto/msdhcp#pxe_chainloading and created a DHCP policy that has the boot.ipxe script mentioned in http://ipxe.org/wimboot as Option 67 (BootFile Name).

My boot.ipxe file contains:

Code:

#!ipxe
kernel wimboot pause
initrd boot/bcd            BCD
initrd boot/boot.sdi        boot.sdi
initrd sources/boot.wim    boot.wim
imgstat
prompt
boot

But boot fails with the following message:

Quote:Filename: http://x.x.x.x:port/win/boot
http://x.x.x.x:port/win/boot... Ok
boot: 920 bytes
Could not boot image: Exec format error (http://ipxe.org/2e008081)

I have made sure that the tips given in http://ipxe.org/err/2e0080 are followed. Still the same error occurs. It seems the boot client is finding the Exec Format Error with the boot.ipxe file itself, and I'm not sure why. Any suggestions would be greatly appreciated.
