So what i do:
I get $WIN_NT$.~BT and $WIN_NT$.~LS folders with this command running XP Professional x64 virtual machine:
\$WIN_NT$.~BT\BOOTSECT.DAT \$WIN_NT$.~BT\migrate.inf \$WIN_NT$.~BT\winnt.sif \$WIN_NT$.~LS\SIZE.SIF
\$WIN_NT$.~BT\ ---> ROOT\PRO1 \$WIN_NT$.~LS\I386 ---> ROOT\I386 \$WIN_NT$.~LS\AMD64 --->ROOT\AMD64
win51 ---> ROOT\ win51ap ---> ROOT\ win51ap.sp2 ---> ROOT\
ROOT\PRO1\setupldr.bin hex address: 0x2060 from "74 03" to "EB 1A"
Final DVD layout:
AMD64 I386 PRO1 win51 win51ap win51ap.sp2
All works fine. Boot and installation OK.
BUT i want to move AMD64 and I386 folders inside ROOT\Source. Editing PRO1\setupldr.bin didn't do the trick. No luck with PRO1\txtsetup.sif SetupSourcePath, like other Windows XP versions. win51, win51ap, win51ap.sp2 copied also to ROOT\Source.
I get "Txtsetup.sif is corrupt error".
Maybe there is an updated tutorial somewhere?
Thanks in advance, sorry for my poor english
