INT 15 - EISA SYSTEM ROM - 32-bit CS ADDRESSING MODE CALLS
        AH = D8h
        AL = 80h to 84h
        other registers as appropriate for AL=00h to 04h
Return: as appropriate for AL=00h to 04h
Note:   these functions are identical to AX=D800h to D804h, except that they
          should be called when using 32-bit CS addressing mode (pointers use
          ESI rather than SI as offset) instead of 16-bit addressing mode
