I have a Asus P5Q-E Mainboard, updated to latest bios to see if it fixes this problem, still no luck. Heres the problem. My connected hard drives goes as follows: X2 80GB in RAID0 - Main OS 500GB Internal Sata Drive 250GB eSATA drive 500GB USB Seagate FreeAgent Harddrive 1TB USB Seagate FreeAgent Harddrive My boot device priority is set as follows: 1st - ATAPI CDROM 2nd - INTEL RAID 3rd - Disabled Each time I turn my PC on - Not after a reboot, the Priority changes! I have to go back into the bios, change it, then reboot successfully. IT changes randomly to things like: 1st - USB FreeAgent 500GB 2nd - USB FreeAgent 1000GB 3rd - SATA 500GB 4th - SATA 250GB 5th - ATAPI CDROM This can apear in any random order, with the INTEL RAID not showing, I have to re-enable it in the Connected Hard Drives options. Any Ideas? I'm pretty lost now!
