Here is my experience slipstreaming 6.66 SATA RAID drivers on XP SP2 Install CD... First let me say that Fernando, you Rock for figuring this out. I think it is worth pointing out (assuming I am correct) that the integration of drivers in nLite (which is the first step) is really only to address the Text Mode portion of Windows Install. This is what saves you from having to use a floppy and F6 during initial setup. For whatever reason (lack of WHQL certification I believe) it does not then use these same drivers later for Windows GUI mode installation. The first time I tried this process, for some reason, nLite did not grab the file nvatabus.sys for inclusion in the install. As a result, half way through loading the text mode drivers, it said "nvatabus.sys file not found" and halted. I redid the process and this time verified that nLite had grabbed the file by checking in the I386 folder for nvatabus.sy_. It worked fine the second time. The second part of your process where you are copying files to the OEMDIR folder is for the Windows GUI mode install. After doing some research this is a common technique for installing non WHQL certified drivers during Windows GUI mode install. Overall, it worked well for me the second time. I not only integrated the RAID drivers but also used nLite to integrate the rest of the nForce drivers. Note that when integrating other nForce drivers you only need to select one INF in each of the relevant subdirectories you want to integrate... nLite grabs everything in that directory regarless of what INF file you select for integration. Good luck to others.
