GRUB

Some GRUB_INIT_TUNE themes I've found online in various places... this is a fragment from my debian:/etc/default/grub file

# Uncomment to get a beep at grub start
# The format unless a file is named is: "tempo [pitch1 duration1] [pitch2 duration2] ..."
# Warning: The menu will not be displayed until the tone is finished

#GRUB_INIT_TUNE="480 440 1"

# Close Encounters/5 Tone:
#GRUB_INIT_TUNE="480 900 2 1000 2 800 2 400 2 600 3"

TODO: I'd like to be able to convert a GRUB_INIT_TUNE line into a /usr/bin/beep commandline. Till then, there is this tip which converts via sox.
