This article is a first for Wired Intel® Ethernet.  This will have links that most of you can’t access.  But it’s okay.  This article is aimed at BIOS writers, and I’ll try to make it so everyone can learn a little bit.  If you’re a BIOS developer, head to the second paragraph.  The next block is to bring everyone else up to speed, so those that write the BIOS please join us back for the second part.  The third paragraph explains why a lot of people won’t be able to get to it.

Basic Input and Output System (BIOS) is the first thing that runs on your computer.  Without it nothing else happens.  If your BIOS is bad, your system is a very expensive paperweight.  The BIOS is the very complex foundation of your system.  And without a good foundation, the rest of the house, the operating system, can’t stand.  Ethernet as a device built onto the motherboard is called LAN on Motherboard, or LOM.  Too often the BIOS is built without thinking about the considerations of the LOM, and that part of the foundation fails.  But for the diligent BIOS developer, how do they figure out what the Wired Intel® Ethernet stuff requires?

Here at the Wired Ethernet labs, we’ve finally come up with a set of documents to help. A complete solution is a top to bottom solution, and this documentation effort recognizes that our once haphazard BIOS help wasn’t cutting it.  You might have heard it by the “BIOS College” moniker in some of our hands on training labs, we’ve released it to CDI so you can review it and make sure that your BIOS is aware of LOM issues.  We have documents for iSCSI, UEFI and Option ROMs.  Plus hardware specific guidance as appropriate.  Start with the Checklist doc and it has links to the other pieces of content.  This is a live document, so it will get more stuff over time, so read it often!

Because BIOS settings are fundamental to normal system operation, we’ve placed this documentation in our secure documentation library called CDI.   You can search for Intel® Ethernet Network Connections – BIOS Documentation / HLD in the search box to find it, or you can click on the link provided.  If that sentence didn’t make any sense and you write BIOS for a living, contact your Intel representative to get a copy.  And tell them the blog sent you.
