Aaaaaahhh... This post helped me get my HP dc7700 working with the dual 80 GB drives mirrored. I had tried various methods, even some given to me by contacts over at HP and the only thing that worked for me was pressing F6 when WINPE was booting up. I downloaded latest the F6 boot drivers from Intel (STOR_F6FLPY32_6.2.1.1002_PV.EXE), copied them to my WINPE System32 in a directory called IntelSata. I edited the WINPEOEM.SIF as indicated above and *poof*, I'm back in business. Thanks!!! Joel
