Grub2 beep, have an useful solution

[Hammer Attila]

hy,

Thank you Arki the topic link.
I will be read full topic. If I found any useful solution, I post this 
list, but if need modify grub2 binary, possible need do a special 
package. If any method is useful and work my machine, I will be put my 
personal ppa with the special package.

Merry Christmas everybody, and thank you the help.
