    ASUS MTRR Settings

    Hi, when I cat /proc/mtrr I get
    $ cat /proc/mtrr
    reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
    reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
    reg02: base=0xc0000000 (3072MB), size= 512MB: write-back, count=1
    reg03: base=0xdff00000 (3583MB), size= 1MB: uncachable, count=1
    reg04: base=0x100000000 (4096MB), size= 512MB: write-back, count=1

    and am looking through my bios for an "MTRR" setting but cannot find a thing.
    I'm running an Asus m2n32-sli deluxe with the latest bios (1903)

    Does anyone know where that setting might be, or another name it might be under? I've crawled the whole menu system several times esp the ram areas. Thoughts?

    Once Linux is up and running it doesn't (usually) worry about BIOS settings.
    From what your shown, MTRR is already active and running on your system, hence the beauty of /proc fs.

    Just continue enjoying Linux.

    I can confirm that.

    I which regards linux, the BIOS is just a dead piece os silicon, for most purposes.

    /proc is a dynamic filesystem which reflect the state of the kernel space memory. That means that, if *it* is in /proc, then it's because the kernel is already handling it.

    You don't need to worry about it.
