CUSL2 with TUSL2-M Bios?

Since these two boards both have the same chipset and other similarities, but the TUSL2-M supports Tualatin and the CUSL2 doesn't.
I'm thinking of trying the TUSL2-M bios in the CUSL2 to see if it will enable it to run a Tualatin without mods.

Have any of you all tried this??

Any thoughts on screwing up the mobo?

Update-
With a modded Tualatin that runs great in my CUSL2, I flashed to the TUSL2-C bios 1012tc, and it worked fine.
Couldn't really tell any difference.

Then I put in an unmodded Tualatin, and it would not even post - boohoo.

Thought it might save having to mod the Tualatins, but at least I know it won't work now.

Man, you've got more balls than I do! I wouldn't risk messing up a hard-to-find MoBo by doing that. Glad you go away with it, sorry it didn't work. You would have become famous if it had!
