It's on the service.asus site now. I just downloaded it. Not quite sure how to get into the BIOS setup though...
Unpack the BIOS Zip to a known location - you'll get a binary image file for the EE-PROM. If you look in your Apps you'll see one called "WinFlash". Run that, point it to the binary file you've just unzipped, and it will do the rest - follow the prompts and
be patient :-)
I also notice they have updated the Intel Chipset drivers for the Atom CPU on 3 Jan, and also updated the
ATKACPI driver which controls power functions (like Sleep mode). If you are experienced enough they are both recommended updates - note that you have to Uninstall the existing ATK driver using Control Panel before you can install the
V1.0.0031 driver. The Chipset driver will install straight over the current one, then do a reboot.
