i slỉpstreamed a xp 64bit boot dvd, integrated sp2. hotfix, sata drive with nlite,isobuster, and driver sata. it seemed good but when i used it to do installation xp setup onto my computer, it didn't worked. there is paragraph like this :'' Line 10774 of the INF file\AMD64\textsetup.sif is invalid.setup cannot continue. press any key to exit. please help me sort it out

Did you use isobuster to include a copy of microsoft corporation.img boot image? That's not necessary, and frankly its a pain to make such image cause you have to reinvent the wheel that is already included in nlite. Just use nlite's boot method, works ok.
Also no one has answeared your post as its anyones guess what your custom made by nlite, txtsetup file contains at line xxxxx.
How should be know when we dont know what the error is referring to at all?
