Grub Init Tune: Mario Bros. Mushroom Powerup

Grub Init Tune - Mario Bros. Mushroom Powerup

This Grub Init Tune will make your computer sound like a Super Mushroom every time you turn it on! This only works for the Grub bootloader - this generally means you need to have Linux (or other Grub-based OS) installed.

Here's the code, which goes in your /etc/default/grub file:

GRUB_INIT_TUNE="1750 523 1 392 1 523 1 659 1 784 1 1047 1 784 1 415 1 523 1 622 1 831 1 622 1 831 1 1046 1 1244 1 1661 1 1244 1 466 1 587 1 698 1 932 1 1195 1 1397 1 1865 1 1397 1"

Installation Instructions

Instructions adapted from https://web.archive.org/web/20150115050225/http://www.iavit.org/~john/debian/grub.html:

  1. Edit the file /etc/default/grub. At the end there are lines like the following:
    # Uncomment to get a beep at grub start
    # GRUB_INIT_TUNE="480 440 1"

  2. Replace the # GRUB_INIT_TUNE="480 440 1" line with the new GRUB_INIT_TUNE line at the top of this document (make sure to remove the "#" from the beginning of the line, as well). Save the file and exit your text editor. Open a terminal window and issue the following command: sudo update-grub

  3. Reboot. You should hear the init tune when the grub menu appears.

Unfortunately no. Grub uses the PC speaker, and that's always set to maximum volume.

If you have a desktop computer, you can turn the volume down by physically popping open your system case, finding the PC speaker attached to the motherboard, and applying one or more layers of scotch tape to the speaker. More scotch tape = lower volume. You're welcome!

I guess you could also put a potentiometer in series with the speaker...?

Here is a command ready to copy paste, (could be used in a post-install script): sudo sed -i 's/# GRUB_INIT_TUNE="480 440 1"/GRUB_INIT_TUNE="1750 523 1 392 1 523 1 659 1 784 1 1047 1 784 1 415 1 523 1 622 1 831 1 622 1 831 1 1046 1 1244 1 1661 1 1244 1 466 1 587 1 698 1 932 1 1195 1 1397 1 1865 1 1397 1"/g' /etc/default/grub && sudo update-grub
Note: some distros have #GRUB_INIT_TUNE (whithout space) instead of # GRUB_INIT_TUNE, in that case remove it from the command.

If GRUB_INIT_TUNE=" is for power up, What is the code for playing a sound when shutting down?

Grub is a bootloader. I am not sure that there is any equivalent as shutting down the computer won’t involve grub at all.

You should better search another way.

e.g running a script with systemd Before=shutdown.target
