    about BIOS settings


    I've read a few articles that say Linux doesn't like Shadowed ROM in the bios settings and that the Memory Hole should be disabled. Is this recommended or does it make a big difference?

    The BIOS shadow is an old hack for MS-DOS. It isn't relevant
    for Linux, or Windows. Dos software makes calls to the BIOS
    to perform ordinary stuff like getting keyboard input and displaying
    text to the screen. If this BIOS code is loaded into ram, the performance
    is better. Modern Operating systems don't make BIOS calls, and don't
    need this feature.

    The memory hole reserves a megabyte of addresses in the middle
    of your ram (that's why it's called a hole) for certain legacy hardware.
    You probably don't want this either.
