Any idea how to adjust the pointer for for SP1/SP2 NTLDR. So we can get rid ARC Path and have full x64 Support?
Are you implying there exist such a patch for SP0?
Are you referring to 2003 or xp ntldr (should not matter anyway)?
What pointer do you mean, inside ntldr (osloader.exe) itself?? If yes, then execution flow can be controlled to your likes...if we just locate the address of that function.
