Bios Mods -The Best BIOS Update and Modification Source

Hello all together,

my english is not so good, but I'll try it.
I have a crossflashed P5KR (with P5KR.rom) to enable AHCI.
It works, but now I've seen this:
100%_ASUS-p5kc-1203_slic-ahci_mod_By_Camiloml
from this forum.
And now my Question:
Can I flash my P5KC with this new .rom and afudos?

Thanks!
