Matt,
Where is that place?
I am searching around but can't find new bios for asus chromebox

I'm adding it as an option to the script right now

If you've already installed OpenELEC (or anything else) in a standalone configuration, the easily way to flash the updated firmware will be via ChromiumOS, the open-source version of ChromeOS. Download the latest x86 version from here: http://chromium.arnoldthebat.co.uk/

then just download/run the script like you would in ChromeOS

Hi Matt, on the wiki page the instructions say to download the AMD64os build and here you say to download the X86 version. Which one do I need to restore mine back to stock?

that post you quoted is *way* out of date; the wiki says to just re-run the script, or if running OpenELEC, to use the standalone firmware updater script from the OP.

X86 version. The chromebox isn't AMD.

x86_64 and AMD64 are synonymous, as the 64-bit extensions to the x86 instruction set were (originally) developed by AMD. OpenELEC (and most of linux) uses the former notation, but the ChromiumOS builds are labeled with the latter.
