I had a mobo(Epox 8KDA3J) fail so I replaced w/ a new Abit KV8-Pro 3rd Eye. All else is unchanged from the prev system which worked well - Athlon 64 3200+, OCZ 512 pc 3200, WD 74 Raptor SATA(w/ XP Pro SP 2 and all programs), WD 250 GB SATA(large data files only), ATI Radeon 9800 Pro, Lite-on DVD r/CD r, and FDD, all in Antec case w/ 380w TruePower ps. Mobo swap went fine, first POST went fine, until it ended w/ "windows could not start properly" screen. Tried Safe mode- failed. Put XP disc in, went thru setup - "setup cannot locate any drives". Even tho the mobo has SATA connectors I repeated setup w/ F6 key push for "third Party RAID driver" and when prompted inserted the floppy which was read but then prompted again for the floppy. Went to another pc and copied the SATA drivers from the Abit CD and inserted it, it was read and the prompt repeated as before. Tried a different floppy drive w/ same result. Reset CMOS several times thru this process. Also tried with disconnecting of front USB cable, FDD, cd/dvd drive, and second hard drive. Short of trying an IDE drive I have no other ideas. I can't lose the data on those 2 drives so I can't just start over. Please advise.
