CPUID. Feature: Access Your Computer Anytime and Save Energy with Wake- Booting Linux from Flash - Oopsilon. I like my computers to be as quiet as possible: if a computer is emitting very little sound, that makes it easier to live with. The noise a computer makes is especially important when it's in a home theatre situation, or acting as a media server; if a HTPC is itself throwing out lots of noise, that detracts from the sound of the movie being played. The ideal case, of course, is for there to be no moving parts: things that move or spin inevitably have friction, and that causes noise. I've tried to eliminate everything that spins from my setup: I have a CPU that doesn't need a fan on the heatsink, and a fanless power supply. However, there's one thing left that is spinning, and that's the hard disk which hosts the Linux installation.
Dropping that would make my system truly silent, so I started looking into how that could be done. Unfortunately, it's not quite that easy.

Coreboot is an Open Source project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload. With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI.
This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. coreboot currently supports over 230 different mainboards. Check the Support page to see if your system is supported. coreboot was formerly known as LinuxBIOS.
