Dell just released a couple of new BIOS for their most recent AW systems. Thanks @Nemesis for the big news.
There's no change log available, so let us know how it goes and whether you notice any big differences.
Maybe if someone could make some screenshots in case there's any visible difference...
I attached the untouched BIOS, it can't be accessed through the official site at the moment.
NOTE: You might not be able to easily downgrade to something older than A08 anymore.
EDIT 2: A09 is not on the Dell site, but file is nowhere to be found. You might want to wait with updating until they release A09.
