X58 Sabertooth RAID 0 enable Trim Bios Mod Help

I think this is (hopefully) related to the post of BIOS modding so I will post it here. Is it ok/safe to flash back to the stock unmodded BIOS if I need to? I might be having trouble with the ICH10R RAID and need to do some troubleshooting.

I don’t see any reason why it should not be ok/safe.
