    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 Developer???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...

    Remove the sata controller Port Multiplier (PMP) support from the kernel to fix this.

    Will this documentation improve the way Linux works with my motherboard?
    The "softreset errors" are mostly caused by some ATA device and often just mean "right now the disk is not ready".
    After a few seconds or less than a second, when the drive is ready, the boot continues.
    Nothing to worry about.

    Ah, nice to read. Since I use a SB7xx. Very nice.

    No, pxelinux.0 is part of syslinux. Newer syslinux versions also have got gpxelinux.0 which is basically the pxe core of gpxe added in front of pxelinux.0 - that can help partly broken pxe loaders, as you only have to replace that file. With that i could boot from a skge card which is only supported in an old private branch of gpxe (which somebody merged into mainline for me for testing). Without that the loader was too broken to boot.

    What is PXELinux? A BIOS replacement?

    Okay, pretty cool!

    I was fairly sure that CoreBoot would never be main stream on desktop mainboards.

    Just looked in my BIOS, and the only thing I need and can't live without is being able to set Cool'n'Quite to begin at 45 degress, so the CPU fan spins at the lowest below 45 degrees.

    Besides PXE, all the other stuff in the BIOS: Don't need it.
