downgrade bios 1406.bin ASUS p5n-e

[kamio]

Hello,

i have mobo P5N-E SLI with XEON 5460 and i upgrade bios on 1406 with microodes for xeon. But i can't overclock processor now I must downgrade bios to 608.bin and EZ FLASH 2 don't allow this operation because bios 608 is older then 1406. Is possible save 608 as newest? 1406 is from 2009 year and 1406 with microcodes is 2015.

Thanks and sorry for english.
