Yup it's all right the 3 files you have listed in post 1 are at d:/$OEM$/$$/OEMDIR, I have typed out the new lines in the winnt.sif file at least 10 times I even copied directly from your post a few time just to be sure. YEs I did integrate as text mode drivers despite the pop up warning in nlite No I didn't do any other drivers just the nvidia driver found in the SATA folder Which actually has nlite integrate 2 drivers 6.66 for xp64 Hmmm, Disable it? I didnt' know you could disable the SI controller. I never enabled it and have never had anything hooked up there. If it can be disabled I assume i'll find an option somewhere in the bios, I'll hunt for it. My **** 3.5 fdd won't post, which is why i'm doing this. Yup the only thing pluged up is the HDs, 1 optic drive, keyboard and monitor
