Hi!

I have an Asus P8B WS motherboard with the latest BIOS release installed. This is causing me many prooblems so I'd like to downgrade to an earlier BIOS version.

The board is used in a pfSense box so I can't downgrade from within Windows. Is there any way to downgrade from within the BIOS?

I have tried booting from a CD and using the EZ Flash Utility but I am prevented from downgrading to an older version.

Any help is appreciated.

Thanks

Phil
 
I dont think it is possible to downgrade bios... at least asus programs dont alow that...

you can try using the amiflash or something like that, so you can reflash the bios.... but it's more dangerous.

or you can get in thouch with asus, maybe if the new bios is a bad release they will release a new one soon.
 
From what I seen on their forums it is a bad idea to try. Those that have succeeded usually ended up bricking the thing.
 
Its really cheaper and a lot less hassle to go to Asus Store site and order the correct bios chip for your motherboard
