    intended to support video bios functions, not all system BIOS
    functions are implemented.

Arguments:

    P - Supplies a pointer to an emulator context structure.
    Number - interrupt number used to enter

Return Value:

    TRUE  = the function was emulated
    FALSE = the function was not emulated
