    Hi.
    My customer has a very old system which unfortunately uses a protection scheme that checks the DMI chassis/board/manufacturer/model etc.

    I have been able to move it to a newer system but only with VirtualBox which lets you override the DMI data.
    Unfortunately VMWare and Hyper-V don't allow you to override the necessary bits.

    I would actually like to run on native hw, or at least try other hypervisors.

    I know that Daz's fabulous loader works by injecting ACPI tables into what the OS sees as the BIOS.

    I was just wondering if anyone knew of a tool which did a similar thing but to patch the DMI data ?

    Thanks

    Qemu can do this via the 'smbios
    type=0,bios-version='1.0',bios-date='2009/10/20'
    i think. Clover can do dropping of firmware OEM tables and also generate (patch) SMBIOS table on-the-fly.

    Clover.. that could be just the ticket! Thanks.


    Ah sweet, I just had a look. I think it has everything I need under the SMBIOS stuff.

    Thanks a lot.
