    Default AMD Publishes New SB Register, Programming Docs

    Phoronix: AMD Publishes New SB Register, Programming Docs

    While most of the time getting new documentation out of AMD is for their ATI graphics processors, today they have pushed out four documents that amount to several hundred pages of information covering their latest Southbridges. The AMD SB700/710/750 chipsets are now well documented in these NDA-free programming guides that also cover the registers for this hardware.Over at AMD Developer Central is the AMD SB700/710/750 Register Reference Guide, AMD SB700/710/750 BIOS DeveloperÔ??s Guide, AMD SB700/710/750 Register Programming Requirements, and lastly is the AMD SB710 Databook.Sure, programming guides and register descriptions for a southbridge is not nearly as exciting as for the latest ATI GPU, but this information is what the CoreBoot developers (the same ones working on Flashrom) have been after for a while...

    now we only need a company that focuses on tinkering a complete oss experience arround amd hardware...
    something like the open source apple with hard+software that works together perfectly.
    so you can get your pear (my imaginary company's name) computer and you know itll work perfectly with linux...
    unlike other companies like acer or asus they dont have to sell crippled hardware with their linux computers, because they cant lose any microsoft partnership contracts....
    haaaaaaa, in my imaginary world everything would be sooooooooooo fine...

    The Pear Computers name has already been used in multiple places as a way to imply "Apple" without copyright infringement. Try again.

    Thanks AMD!

    It's so nice to finally see more major hardware companies actually getting the point that widespread knowledge of how to use your hardware is good, and helps you sell more chips...

    I work for a big semiconductor company, and have met many older managers who simply cannot come to terms with idea of giving anything away without strict conditions and renumeration, even if restricting information in the end hurts the company far more than any advantage it confers. There's a sort of ingrained conservatism and downright control-freakery that seems very hard to get rid of except though generational change.

    This is so cool!

    CoreBoot really is an important project that many don't care much about. Apparently also Michael

    But it really is important to have an open source BIOS, as it is possible for the BIOS vendors to include a secret hyper visor that in "best case" "only" monitors what you do.

    In "worst" case, it can forbid you from doing some things.

    So CoreBoot really is important, and anything that helps that is exceeding good news

    Also with CoreBoot you would be able to encrypt your harddrive, and have CoreBoot ask for the passphrase.

    Heh, that's just plain paranoia talking.

    You are probably right. Microsoft would never want to forbid Linux from running on PC's.

    I would definitely get an AMD based motherboard if it meant a free BIOS. Found this on Google: http://www.coreboot.org/pipermail/co...er/039094.html

    If someone wanted to do something like that really bad, they'd just implement it in hardware. (Palladium relies on custom TPM chips anyway).

    Your gfx card most likely already supports HDCP, a technology designed to restrict your actions. Is an open source BIOS going to help you against that? No.

    You'd need "Open Source Hardware" for that. But while everyone can get a compiler, not everyone can get his own fab, so that's a pretty pointless discussion.
