ipxe can't load winpe when installing windows on HP380G8 and Huawei

[ipxe2windows]

I'm installing windows 2k8 server for my company and find ipxe perfect for the job.

HP360G7 and HP360G8 works fine. But here is a problem: ipxe can't load winpe correctly when installing HP380G8 and HUAWEI RH1288 V2-8S.
The following is my ipxe file:

#!ipxe
cpuid --ext 29 && set arch amd64 || set arch x86
kernel wimboot
initrd ${arch}/media/bootmgr bootmgr
initrd ${arch}/media/Boot/BCD BCD
initrd ${arch}/media/Boot/Fonts/segmono_boot.ttf segmono_boot.ttf
initrd ${arch}/media/Boot/Fonts/segoe_slboot.ttf segoe_slboot.ttf
initrd ${arch}/media/Boot/Fonts/wgl4_boot.ttf wgl4_boot.ttf
initrd ${arch}/media/Boot/boot.sdi boot.sdi
initrd ${arch}/media/sources/boot.wim boot.wim
boot

from the console, it loads all the files correctly and then goes to black till reboots from nothing.

Can anyone please help here, and many thx to that.

I've heard about this problem before. If your boot.wim is more than 330MB you'll have to make it smaller. If that doesn't work, you might need to use an older version of WinPE. If you feel adventurous, you could try running the entire thing in Bochs or connect up WinDbg and try to understand _why_ it's failing.
