Coreboot at Your Service!
Don't let your PC's closed-source BIOS stop you from doing what you want with your hardware.
Once the configuration parameters are set, run make again to compile the library:
$ cd ../filo $ make
Now you can set the options for FILO. Again, simply press Enter for all the prompts and accept the defaults.
Obviously, not all of the above options actually are needed. For instance, you don't need XFS, JFS or Minix support if your system boots off an ext2/ext3 partition. Once you've gotten everything running, you can come back and switch off the options you don't need, which will reduce the size of the coreboot image.
Notice the following line near the top of Listing 2:
GRUB menu.lst filename (MENULST_FILE) [hda3:/boot/grub/menu.lst]
My test EPIA-M II system has OpenSUSE 11.0 installed and uses the GRUB bootloader. I chose to include GRUB's interface support inside FILO, and this is the place to specify the location of GRUB's menu file. If you don't plan to use the GRUB interface (for instance, if your Linux distribution uses LILO for booting), you need to specify the correct line to load the kernel and initrd, as shown in Listing 3.
After setting the FILO's configuration parameters, compile FILO by running make again. The compiled loader is placed here: filo/build/filo.elf.
At this point, you've prepared the payload. Now, you need to generate a coreboot image. First, let's take a look at the config file that is used during the coreboot build (Listing 4):
$ cd coreboot-v2/targets/via/epia-m $ vi Config.lb

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy
Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
Learn more about catching the bad guy in this free white paper.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

Some clarifications
Hi there,
@Anonymous: there's a list of supported hardware. Basically if your motherboard's components are already supported, the motherboard shouldn't be very hard to get working, but if this isn't the case, the needed work can be quite consistent.
@Boris: The v3 was dropped in favor of v2 and is now unmaintained (except for Via Epia targets). Many of v3's features were backported to v2, which still has much better hardware support than v3.
The coreboot wiki page is a good reading, and the people from the IRC channel or from the mailinglist are a great source of help also.
Thank you for the
Thank you for the article.
Could you try to boot the latest trunk version? I've tried to boot trunk svn revision 4974 but can't get even serial output from my epia-m.
Does it work on my box?
How the heck can I find out whether coreboot will work on my machine? I'm using Linux, of course.
