I'm having a similar problem. Installing Win Vista Ult Full, I get it (Seagate 1.5 TB) partitioned, reboot, set BIOS to enable SATA booting, restart, and the board just hangs at the SATA drive splash screen... Have you had any luck figuring this out? It would be nice if someone would respond and help us out.
No as you can you are the only other one that has replied with something similiar,I did find some info on seagates site about a firmwear update to some of there HD's, I checked mine and it had the latest,,I also checked the bios and flashed it to see if that would help but it did'nt,,I just cant get it to boot off the SATA,,I can use it If I use an IDE drive as the master,but whats the point ,,,so i have switched to an ASUS mb using an AMD chip and it worked the first time no issues,,,,and btw i have asked many ? from the AMD guys and I got more response's from them than i ever did here...take that any way you want...
Thanks for your feedback on the issue. I created a tread called "How tell if BIOS sees SATA drive on D845PEBT2 mobo?". If it helps any, you could check it out. I have been getting some excellent help from an Intel guy named Rajiv Doolub. We're working through possible solutions. Hopefully we'll figure it out. Hope this helps.
