SdtInvalidSignature(XSDT) during real hardware test

[kennystrawnmusic]

According to the OSDev wiki:

"the XSDT provides identical functionality to the RSDT but accommodates physical addresses of DESCRIPTION HEADERs that are larger than 32-bits." - ACPI Specification v5.0. This means all addresses are now 64 bits. If the pointer to the XSDT is valid, the OS MUST use the XSDT. All of the addresses will probably be 32 bits, and if you are not using PAE, you couldn't use higher than 32 bits, but the spec says you should use this anyway.

Yet when I attempt to test on real hardware (ASUS VivoBook E203M) I get this:

So can anyone tell me why this crate (or at least the published version thereof) isn't seeing the XSDT as a valid table? Should be the correct signature on UEFI in particular.

As for using the git version: would need to know which function replaces "get_sdt" in it because it seems to have disappeared which means a lot of refactoring would be necessary.

Submitted Issue #175 since I'm assuming it's a bug with this crate.
