You can now modify setupldr.bin of the follwing windows:

• Windows Server 2003 SP1
• Windows XP Professional x64 Edition
• Windows Server 2003 x64 Edition
• Windows PE 2005

The setupldr.bin of the above versions is the same and has a checksum check built-in so when you try to modify it you get:
"NTLDR is corrupt. The system cannot boot."

In order to crack it:

1. open it with your favorite hex editor
2. goto hex address: 0x2060
3. change "74 03" to "EB 1A"
4. save it

I also uploaded it for your convenience at:
File is now attached so people don't have to wait for a download ~ Alanoll

Now you can replace:

1. all occurrences of "i386", "I386" to "ABCD" (where ABCD is anything you want - 4 characters long)
2. "\amd64", "\AMD64" to "\EFGHI" and
3. "amd64\", "AMD64\" to "EFGHI\" (where EFGHI is anything you want - 5 characters long)

Do not replace all occurrences of "amd64" since some of them refer to a section of txtsetup.sif

In order to find what files need to be copied to the directories ABCD and EFGHI open command prompt, go to the directory you have txtsetup.sif and enter:

and copy the files listed there from I386 to ABCD and AMD64 to EFGHI.

For anyone curious, open the setupldr.bin with hiew, goto the above hex address and see the surrounding assembly code.

hmmmm.... is the boot folder in the root named 'XP64'? did you copy the entire cd to the \SETUP\XP64\ directory?
