[tlug] Should I be concerned about this "BIOS Bug"?

[Dave M G <martin@example.com>]

TLUG,

Whenever I boot, there's this error that appears on screen. It usually 
flickers by so fast I don't really see it. But recently I was able to 
actually see it long enough to record it.

It says:

PCI: BIOS Bug: MCFG area is not E820-reserved
PCI: Not using MMCONFIG

The term "BIOS Bug" sounds very scary. But, on the other hand, my 
computer has been working just swell. At least, every problem I've ever 
had has been resolved on the OS or application level.

Of course the first thing I did was Google the terms of the error. 
Oddly, all it really came up with was all these guys posting their boot 
logs, but no one seemed to have much in the way of commentary or 
explanation of it. Certainly not in any form I could understand.

So... should I be concerned at all about this?
