That is great news!

You should be able to check /proc/acpi/dsdt.
I can see a dsdt file in /proc/acpi/, but I have not found a way to see its content.

Is 0x1f71f000 an address that was sent in the memmap to the OS? Maybe
dmesg can show what address ranges the OS used.

I have got the dmesg of UEFI OS and paste it at the following. I can see "SMBIOS=0x1f71f000" and the error message "DMI not present or invalid". But, I still cannot determine the cause.

I find another two error about the "ACPI Incorrect checksum". I will check my code to find the reason. Is there any other problem that can be got from the dmesg?
