GRUB makes high pitched noise....forever

Whenever I get into grub it makes a high pitched mosquito-ringtone type noise. The type that your parents are supposed to be unable to hear. When I first installed Ubuntu 3 years ago, it did the same thing, but it stopped after 2-3 seconds. Now, in Arch and Ubuntu (32 and 64bit) it just keeps going forever until I boot. I have tested it until I had to start an OS or risk a migraine.

Does anyone else get this? The problem has followed me across 3 computers, and others in my family have heard it too, so it isn't just me or my machine.

[off-topic]Where would this go in the Arch Support section? It's not the Kernel....and it isn't Arch specific[/off-topic]

Try a different color configuration in menu.lst.
Stuff known to make noise: graphic cards, monitors, power supplies, $random_capacitators

Re: GRUB makes high pitched noise....forever

Once when I run a virtual machine in KVM, and while it was waiting at the Grub menu scree, I noticed that the KVM program is using 100% of one cpu. I asked around, and the explanation I got was that Grub is a old-style 16bit application only having access to the BIOS routines to access the hardware, so it is busy-loop polling the keyboard to see if you typed anything.

So, maybe this is the source of that noise.

I run colorless. And like I said, every computer I've installed it on has done it.

Interesting theory damjan

Re: GRUB makes high pitched noise....forever

I used to have a P4 3.0 ghz cpu with hyperthreading (Prescott model) and they were notorious for overheating.  They had a sensor that if it overheated, it would sound the alarm.  The alarm was a pitch my dad could not hear...but I could allllllll the time.  So, whats your processor?

One was a P4M 1.8Ghz, another was a P4 1.2Ghz, and this one is a Core 2 Quad 3.0Ghz.

Did you try opening up the case?  Try taking out everything and see if its still there.  I'll bet its the processor screaming =p
