| Today, I try test on real system with AHCI controller. I use USB with: -Grub4dos: 27.6.2012
 -RUN: 22.7.2012
 -DPMS: 12.06
 -Windows XPSP3 iso (from MSDN), place in folder ISOS on USB
 -Firadisk, WinVbk: try all
 
 First time:
 I use this code
 
 复制代码
title Setup Windows from ISO (FiraDisk with DPMS, 2 Steps)\nSelect file ISO and Press Enter (3 times) to continue booting at the 1st time,\n\t\t and Press S (for USB) then press H to continure setup at step 2.
command run --fira dpms:/srs/dpms.lzma --autolist=/isos/

command run --wvbk dpms:/srs/dpms.lzma --autolist=/isos
I got error BSOD 0x7B.
 
 2nd times:
 I use this code:

It work OK, no BSOD. But some machine load very slow.
 
 3rd times:
 I try places file ISO on hardisk. Oh, I do not need load ISO into RAM. I can install OS.
 
 Can you tell me why?? Something wrong?
