    NO, it is still post 209

    The BIOS mod was tested & it works, so what is the problem for you to just do you machine & then confirm yourself what SLIC it is?

    No problem. Had not thought of that. I'm sorry for any problem I may be causing. No one told me post 209.

    Thanks ;)

    I can do it again, more accurately ;)
    I was quite upset when I saw how stupid was my mistake...

    Yep… The very existence of DCCU tells me (and BIOS code browsing too), CMOS offsets are same across similar model groups.
    I.e. CMOS offset to SataControllerMode should be somewhere close to these.
    Code:
    Drives.ParallelATAChannel0
    Drives.ParallelATAChannel1
    Drives.ParallelATAChannel2
    Drives.ParallelATAChannel3
    Drives.ParallelATAChannel4
    Drives.ParallelATAChannel5
    Drives.SerialATAChannel0
    Drives.SerialATAChannel1
    Drives.SerialATAChannel2
    Drives.SerialATAChannel3
    Drives.SerialATAChannel4
    Drives.SerialATAChannel5
    Drives.SerialATAChannel6
    Drives.SerialATAChannel7
    Drives.SataControllers
    Question:
    Any easy way to find what CMOS offsets to the settings above are?

    Wow - "USB.USBWake" value="2" :eek:
    What are the string values?
    Is it for WOL for USB NIC?
    Or wake on insert some USB device?

    Obelix is the acpitbl dump you posted from the same version of the bios as the one you posted a link to on dells website (A12)
    The acpi table dump only shows one entry in the RSDT, ie the RSDT appears to be 4 bytes smaller than the one in the bios
    Code:
    Root System Description Table: 0x000FDE64
    
    52 53 44 54 28 00 00 00 01 AD 44 45 4C 4C 20 20RSDT(.....DELL

    61 00 00 00 90 DE 0F 00                        a.......

    If You are using an older version of bios on your C810 than A12 could you upgrade it to A12 using dells update then repost the acpi table dump thanks.

    Optiplex GX520

    Here in the forum the optiplex Gx620 was modded succesfully.

    The Optiplex GX520 is nearly the same machine. Someone installed the mod and said that when you check with slictool it says invalid slic.

    Did someone installed succesfully the mod on a GX520 ?

    To en4rab & atapuerca:
    I can post updated HDR tool. I don't have any time to test it...
    It has enough functionally for self testing - just need to write some test cases...
    Code:
    Wrong section type - should be A, a, C, c
    A - 2 bytes module length + 1 byte module type
    a - 1 byte module type + 2 bytes module length
    C - 4 bytes module length + 1 byte module type
    c - 1 byte module type + 4 bytes module length
    Do you want me to?
