I try make OEM SLP WinXP Pro N version from VL. File NT5INF.CA_ need the same what VL not from RTL version. If replace this file from RTL have install error
Dont change it. All you need is to change the setupp.ini and the oembios files. That should work.. At most, I would change the dpcdll.dl_ and pidgen.dll files, but that is mostly unnecessary in my experience.
The way I read it is he has pro VL and he wants to convert to pro N oem there is delta for en_windows_xp_professional_n_with_service_pack_3_x86_cd_vl_x14-78118.iso
Yes. I convert VL N to OEM SLP N. Need only change 2 files DPCDLL.DL_ and PIDGEN.DLL + OEMBIOS files + WINNT.SIF and change SETUPP.INI to OEM and working
