Using the acpitbl script attached: # cat /proc/acpi/fadt |acpitbl |grep IAPC_BOOT_FLAGS IAPC_BOOT_FLAGS: 0x0003 (this example has bit 0 and 1 set, we are looking for bit 3). If you have an acpidump output, you can do it this way $ acpixtract FACP acpidump.out | acpitbl | grep IAPC_BOOT_FLAGS IAPC_BOOT_FLAGS: 0x0003
