This is an old revision of the document!


The procedure still seems a little unclear but some variation of:

  • to get into root: <ctrl><alt><right-arrow>
  • login as root. Default password is test0000
  • <ctrl><alt>t then type shell

This step will alow the quick boot of Seabios and entering the Linux distro without pressing any key shortcut

We will set these flags:

GBB_FLAG_DEV_SCREEN_SHORT_DELAY 0×00000001
GBB_FLAG_FORCE_DEV_SWITCH_ON 0×00000008
GBB_FLAG_FORCE_DEV_BOOT_LEGACY 0×00000080
GBB_FLAG_DEFAULT_DEV_BOOT_LEGACY 0×00000400

with this command:
# /usr/bin/set_gbb_flags.sh 0x489
sometimes this is at:

# /usr/share/vboot/bin/set_gbb_flags.sh 0x489

Your flash should have been written now.

# crossystem dev_boot_usb=1 dev_boot_legacy=1
Not really needed but just to make sure.

Now…maybe we have to reinstall Chrome OS or install Gallium OS?

After installing Huge Green Bug's xubuntu 14.04:

  • disable right-clicking by clicking on right side of touchpad: add to ~/.xsessionrc: xinput –set-int-prop $ID “Button Right Click Enable” 8 0
  • disable touch to tap: add to ~/.xsessionrc: xinput –set-int-prop $ID “Tap Enable” 8 0
  • note that both of the above commands assume that ID has already been set as already appears in .xsessionrc: ID=`xinput | grep cyapa | cut -f 2 | sed -e 's/id=//'`
