The ACPI compiler and disassembler tools from https://www.acpica.org/downloads will do the trick to dump the ACPI table and disassemble it. But the "switch" option provided by to tools may confuse user on actually how to dump a table and disassemble it. And here is quick steps on how to do it. At the time of writing the author is using iasl-win-20150619 tool from www.acpica.org
Steps in windows:
1) Extract the package
2) Open a command prompt and run the following command at the location of the extracted package
3) "acpidump -b", it will dump a few binary out (dsdt.dat, facp.dat, etc...)
4) "iasl -d dsdt.dat", it will disasemble to dsdt.dsl and you can open it with text editor.

NMAKE: Fatal Error U1077 ...
If you ran into NMAKE: fatal error U1077 using nmake in command prompt when a return code of '0x0000135', your problem is most likely due to the environment variable not being set right.
Assuming the Makefile and the C file which you plan to compile is working on other system.
You may try running "vcvars32.bat" in your command prompt to set the compiler environment into it.
