If the drive doesn't show in the BIOS, there is no way for any software to access it, since all software uses the BIOS to access the HDD, at least preliminarily. You could try the Knoppix LiveCD, since linux uses direct HDD access to bypass the LBA limitation, but it still (I think) initializes the drive using the BIOS. You may be out of luck.
However, a weird trick might just do it for you:
