playing a tune at startup

Wed Apr 8 17:36:19 EDT 2015

I love that crazy idea! I have yet to get my USB to serial adapter working in Grub2 (need sighted assistance to finish the job as those of you on the Gentoo-accessability list saw me post last week). This would be great in the meantime and great if my USB to serial adapter wasn't around... and great for folks who don't want to bother setting up a serial terminal.

BTW, John, there's a slight bug in your script. The grub init tune and play routine accept a value of 0 as a rest and, if a very low value like 1 is used instead, rounds it up to something that can be played like a 20 or 40. The beep utility takesa  value below the lowest freq the speaker can play and converts it to a rest. As a result, the 1 I used as a rest in my tune was a rest with beep but a low grumble (sounded like a drumroll through a PC speaker) with Grub.

I'd suggest having the script accept values of 0 in the grub init tune and converting them to 1 before passing them to beep. That way, both Grub and beep would produce similar output.

If you pass a value of 0 to beep for the freq, it skips it.

I'm not sure you can get a beep for each item on the grub menu any more. 
  You used to do that by editing the grub config file and inserting n 
ASCII character 7 on the title line for each boot stanza. But there is 
no reason that has to work at all any more -- it would depend on how the 
grub menu is displayed. But another problem is that the grub config file 
is generated by update-grub now. If you edit the config file, it will be 
over written next time you run update-grub.

Crazy idea... We should try to get the grub developers to beep the morse 
code for the characters of each grub menu item. Perhaps if you press the 
right arrow key, it beeps the morse code for the first letter of the 
line. Press it again, it beeps the second letter. Even if you don't know 
morse code, you could do it slowly enough to look it up. For most items, 
you'd need only the first letter or 2.
