Good afternoon.
I'm writing simple BIOS for init Intel Atom E6xx platform.
Already wrote much of the code, but there is a problem.
The documentation contains links to documents
"Intel Atom Processor E6xx Series BIOS Writer's Guide".
Download it from the Intel site is not possible for private persons (only for companies).
Who could help?
Maybe you have a BIOS Writer's Guide for other platforms...

Can be PM.
A great thanks.

I am going to assume that you are aware that there is no such thing as a "simple" BIOS, since BIOS is responsible for initializing all hardware (not just the CPU, which means your "BIOS" must be custom for that specific MB and be aware of initialization procedure for all hardware attached to the system or embedded on the MB)

I don't know where you got that document name, nor do I know why you think its only available to companies, but a simple search of the Intel website showed the correct document to be "Minimum Boot Requirements for the Intel Atom Processor E6xx Series: Application Note" as a supplement to the "Intel Atom Processor E6xx Series Datasheet"

there doesn't seem to be any "Bios Writer's Guide" for the E6xx Series (there are "Bios Writer's Guides" for other Atom families, but not the E6xx series) -- Intel is usually pretty good about giving out documentation and specifications, here are a few links (these are links to view the documents online, the document search will also give links to download the documents as PDF)

boot requirements:

This document may be currently unavailable (possibly because it's obsolete) but there are some references in 2011's datasheet, see attached screenshot.
No, I don't have this guide, only a datasheet that references it.

Yes, I know.

Thank you for your attention.
As Nable say, E6xx datasheet referencing to "BIOS writer's guide" many times. So, I have Ex66 datasheet, I also have "Minimum Boot Requirements" but it is not enough to write reliable code.

Do you know where I can find it?

Thank you.

Maybe you have BIOS writers guides for other platforms?

No, I don't have any of them on my machines but if I ever need one, I would try something like this: https://www.google.com/search?q=intel+B ... letype:pdf

As you could see, JAAman gave you a link to Intel's search page. It returns some results (http://www.intel.com/content/www/us/en/ ... 9s%20guide) but these results are marked as privileged. It looks like a dead-end but did you try to register at https://www-ssl.intel.com/content/www/u ... on-po.html ?

Btw, could you tell a bit more about your project? Boards often come with datasheets or at least some board-specific software packages (possibly, in binary form) so customers can boot WinCE or Linux out-of-box.
