I have an intel MOBO D845PEBT2 that I have been using since 2003. I have always had IDE drives. Last week I tried to add a SATA drive since the MOBO came with 2 SATA ports. I am able to write and read to the 1tb seagate drive, but it will not boot. I have gone back to P08 and lost my usb mouse, so changed back to P10. There is no option in the bios under advanced where it lists drives where I can make the changes that were referenced in the document "Troubleshooting boot problems". Is there a special bios that gives the option for advanced > Drive configuration menu? or in a SATA Drives menu > Chipset SATA Mode > set to IDE? HELP!!!!!!!!! I tried to install xp and it didn't find any SATA Drive. of course I was using a IDE DVD drive to do the install from.
