Well I tested it on machine with 8GB but surprisingly the ACPI BIOS tables are mapped to physical address 0xC9780000, not close to 0xFFFFFFFF. so I cannot test rollover. I asked also DJ Delorie but he told me he don't have such DPMI knowledges. I hoped someone here will know and help. I have no idea where else should I ask and search :(
