My SATA2 seagate harddisk running in ACHI mode (Gigabyte RAID) seems to be unable to boot up at times. It's only in rare occassions, but it happens. The Gigabyte RAID bios detected the HDD, but it doesn't try to boot from the HDD at all. All I get is "Disk boot failure" after seeking for boot sector in my floppy (didn't have a startup disk in there).

Amazingly though, once I press CTRL+ALT+DEL, and it restarted, the drive will boot just fine. Again, this happens once in a blue moon.

Don't know if this is BIOS related, but I started seeing this problem only after F4 beta. The F5s didn't fix it. I can't test each bios to be certain since it's intermittent. Anyone else facing this problem?
