Flashing RAID board with possibly non-RAID BIOS?

[FatBurger]

Ok, here's the deal. I own a TH7II-RAID, and I have a...not publicly released BIOS that might be for the non-RAID version. Abit's site shows a single BIOS for both TH7II and TH7II-RAID boards(Link). I haven't been able to get a hold of the person I got the BIOS from, and Abit's site doesn't contain any information.

So what do you think? Could I flash it safely? It allows for higher Northwood voltages, which is why I want it.

In case anyone's interested, apparently there aren't actually separate BIOSes for RAID and non-RAID versions of this board (or possibly all Abit boards), and the BIOS flash worked perfectly. Now I've got up to 1.85v for my Northwood, so I should have lots of fun overclocking tonight.
