However, it is quite broken ATM. :-( Alternatively, you may use acpiexec from ACPICA: fetch http://www.acpica.org/download/acpica-unix-20101013.tar.gz tar xpf acpica-unix-20101013.tar.gz cd acpica-unix-20101013/tools/acpiexec gmake ./acpiexec Actually you need to extract ACPI tables from your BIOS (or UEFI in your case) to use with acpiexec. acpidump(8) gives you what you want BUT you cannot use it with acpiexec directly. You need to dump/extract tables using Linux pmtools: fetch http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/pmtools-20100825.tar.bz2 fetch http://people.freebsd.org/~jkim/pmtools-20100825.diff tar xpf pmtools-20100825.tar.bz2 cd pmtools patch < ../pmtools-20100825.diff gmake sudo acpidump/acpidump -o ACPI.dat acpixtract/acpixtract -a ACPI.dat Note the pmtools patch is really a hack but it should work. ;-) Good luck, Jung-uk Kim * PS: If anyone has enough free time, please fix acpidb.
