Lawyers - are you trolling? Just install the beta BIOS or wait for official. You can use flashback feature if you have problems booting.I am not quite sure that MSI have a legal right to post beta BIOS as an official option on the main site, thus leaving the risk for bricking users' boards open and high.
And if I brick my board, they wouldn't even accept the RMA because it's flashed with a beta.
Someone to contact the lawyers and ask.
