I have a Dell PowerEdge 2650 with on-board Adaptec Perc3Di SCSI RAID controller (mirrored 18GB drives for OS). It also has an add-in Adaptec 2810SA 8-channel SATA RAID card. After installing FC3, and installing GRUB to the MBR of the mirrored 18GB drives for OS, when I boot the system, I get "GRUB Loading Stage2Read Error". The Dell system and both RAID controllers were updated to their latest BIOS versions prior to installing the OS. I even tried (to no avail) booting into rescue mode, chrooting, and running: "grub-install /dev/sda". Any help would be greatly appreciated.
