@node Vendor power-on keys
@chapter Using GRUB with vendor power-on keys
Some laptop vendor provide an additional power-on button which boots another OS.
GRUB supports such buttons with GRUB_TIMEOUT_BUTTON, GRUB_DEFAULT_BUTTON,
GRUB_HIDDEN_TIMEOUT_BUTTON and GRUB_BUTTON_CMOS_ADDRESS variables in
default/grub. GRUB_TIMEOUT_BUTTON, GRUB_DEFAULT_BUTTON and
GRUB_HIDDEN_TIMEOUT_BUTTON are used instead of corresponding variables without
_BUTTON suffix when powered using special button.
GRUB_BUTTON_CMOS_ADDRESS is vendor specific and partially model-specific.
Values known to GRUB team are:
