LiveCD: unpacking firmware
I had a question related to the amd64 minimal livecd.
I was not sure of the appropriate mailing list, so please forgive & redirect if this is the wrong one.

What exactly is happening at the "Unpacking firmware" stage of the boot process?

Is there a way to find out exactly what firmware is being loaded? Or a way to boot without loading the firmware?

Why? It is a somewhat strange reason. I am having issues with a high-pitched hum coming from the audio jacks (occurs on both MB sound and a creative sound card)

I have a very nice sound system (a sound board, studio monitors...I am an audio hobbyist), and no other system has these problems, so I am relatively sure that it is not the speakers/cables.

I have been booting from the liveCD, and I have pinpointed the point at which the hum starts to something near the *Unpacking firmware stage.

I realize this is somewhat esoteric, but it renders my system almost useless, and would greatly appreciate any input.
