Are there drives connected to this system other than the two you're discussing for the software RAID sets? I know you said that you can't take the system down for an extended period of time. Do you have enough time to connect the two 1TB drives and nothing else, and do a new install? It would be useful to know if such an install booted, to exclude the possibility that there's some fundamental incompatibility between some combination of the BIOS, the Highpoint boot ROM, and the 1TB drives. If it doesn't boot, you have the option of putting the bootloader, kernel, and initrd on some other media. You could boot from an optical disc, or a USB drive, or CF.
