As soon as I press The Ctrl key, it errors saying something about "this boot requires 9K of low DOS memory and you only have 400 K. ". And it hangs there.

Secondly, the WIKI says to use the Function-Arrow to get the command shell from the ChromeOS login. The arrow is reversed at least with respect to the keyboard that comes with the ASUS.

Thanks!!

you're hitting CTRL-D too late, since SeaBIOS is registering the key presses (which is why you're getting the error) and not the dev mod boot screen. Press it earlier. even if it means before your screen turns on (since your TV is likely being too slow to init).

Heheh... The TV is brand new... But I'll give that a try. Thanks!
