I used some cheap work-around which loads the modified ACPI table just in the windows registry, it needs Windows testmode enabled: Replacing the compiled ACPI table with the UEFI Tool is possible as well, the problem is that those bay trail based tablets tend to have some kind of checksum protection which prohibits any modifications.Editing ACPI = DSDT is the hardest part Injecting it live, is possible with Clover Bootloader and even Grub bootloader. Just disable HPET ACPI table in memory before OS loading.Please reinstall Windows XP after update the latest version BIOS.Diagnostics Index Hard Drive Diagnostics Memory (RAM) Diagnostics Prime 95 Stress Test FurMark Video Stress Test Windows Performance Toolkit (XPerf) Diagnostics CPU Stress tests Video 2 (4 tests) Windows OS. Driver Reference Table Suggest-A-Driver DRT Search Sysnative Forums DRT Mirror Diagnostics.On traditional BIOS systems, two memory areas need to be searched.

Recompile facp.dsl $ iasl -sa facp.dsl See this post: load custom ACPI table in Linux

Change 'reduced hardware support' from 1 to 0. To use them from CLI: $ acpidump -b $ iasl -d facp.dat Now modify facp.dsl with a text editor.

You can use the tools here to dump the ACPI tables in Windows: ACPI tools Windows binaries.
