    If you are in DOS, maybe there are some BIOS Interrupts that could do that
    in a transparent way. ACPI comes also to mind, but probably will work, if
    ever, on only recent MBs.
    Otherwise, in DOS, you may also write directly to the Super-I/O controller,
    without the need for a driver. If however you want a solution that should
    work with many Super-I/O chips, you have to get their datasheets and/or
    programming manual and have to implement code that identies the chip and the
    switching with the appropriate sequence of cookies. Tedious works...

    I know of some work for the Linux kernel to identify the Super-IO chip.

    I only teste the smcio code on one mainboard.

    Bye
