        I don't know what the AMI AT is, but if it's the usual AT
        (NOT XT) clone with a 32k BIOS that doesn't include any
        BASIC, then something like F800:0000-7FFF or
        F000:8000-FFFF should do the trick.  The address range
        that you mention is not possible in real mode.
