    Software uses a Loader to emulate the SLIC2.1 information.
    A BIOS mod puts the SLIC2.1 information into the BIOS itself.

    A loader is much easier to detect and disable, but still relatively safe.

    Can the software modification, I meant loader, pass MS's validation?

    Does the BIOS mod only modify the SLIC section in the bios? IF so, i dont think it will affect the whole BIOS, it should be safe as well, isnt it?

    BIOS modding does carry some risk, especially if doing it on your own. It's always possible something might go wrong during the flash, and thus you run the risk of bricking your board. I have it done it multiple times without issue with AndyP's tools.

    The bios mod may rearrange tables within the bios in order to incorporate the Slic table. Sometimes something such as the EPA logo may be deleted in order to provide space for the Slic table. Is is quiet complicated because all manufacturers bioses are different and are continually being refined.
    When the bios is flashed generally the whole bios is overwritten.

    Andy P's bios tools are brilliant pieces of programming but the cannot cope with every bios.

    I have successfully used Andy's tools several times on Gigabye, Abit and Asus boards but these are considered to be amongst the easiest to modify.
    If in doubt consult the experts.
