commit c8764595acb4eca89ce7e6d2dabf7c6e8eac7704 Author: Stefan Reinauer reinauer@chromium.org Date: Fri Mar 30 17:10:49 2012 -0700
[ChromeOS] Don't initialize VGA Option ROM in normal mode
ChromeOS features two different modes: normal mode and developer mode (aka jailbreak mode). In developer mode, we need to display a warning screen for security reasons.
However, in normal mode we want to boot blazingly fast. Therefore we don't run (VGA) option ROMs, unless we have to print something on the screen before the kernel is loaded.
