Don't delete anything. Setuporg.exe which has to be placed in XP_INST.IMA \setup\ : 1) In case BTS driver packs were used, or any other method using "fake setup" at start of GUI- just use I386\setupORG.exe, which should be the original MS setup.exe. 2) Original media/unmodified setup.exe- extract it from I386 (7zip or default MS expand.exe) and rename it to setuporg.exe. Don't worry about winnt.sif for now, that's optional. Haha, oh dumb me. I thought when the instructions said to "extract the setup.ex_" that you had to take it away (delete) from the installation image =D I didn't know the setup.ex_ was the setup.exe in a compressed form =) Well I shall try it again tomorrow, ill post the results =) Worked perfectly on Asus EeePC 901 with a Windows XP Pro SP3 image
