HPA from N680SLI-DQ6 BIOS Backup

All,

I recently flashed the BIOS on the above board (flashed to ver. F5). I booted off a floppy and ran the flash program. Before commencing the flash, I backed up the BIOS to the 'disk'. I though this would back up the BIOS to the FDD or secondary BIOS, but it created a HPA on the primary HDD and dumped the BIOS there. Unfortunately, that disk was part of a RAID 5 array and it got kicked from the array on reboot because it had 'srunk'. Fortunately, there was a hot spare, BUT this leaves me with the question:

How do I remove this HPA from the HDD?

So far I have tried booting the XpressRecovery CD and looking for the Remove / Delete option (there is none). The onboard XpressRecovery BIOS option is equally unhelpful. I have also successfully removed the HPA via Linux and hdparm and made the change 'permanent' via low level ATA calls, but the BIOS just goes ahead and recreates it on POST

Anyone have any clues?

cheers,

Rich
