Which of the following options should you add to the kernel line in your GRUB configuration file to enable ACPI support in the Linux kernel?
  1. -acpi on
  2. apm=on
  3. acpi=on
  4. set acpi on
Explanation
Answer - C - You should use the acpi=on command to the kernel line in your GRUB configuration file to enable ACPI support in the Linux kernel.

Key Takeaway: You can enable ACPI completely by appending acpi=on to the kernel boot command line in the grub.conf file. To do so, open /boot/grub/grub.conf with a text editor. Append acpi=on to the kernel boot command line in /boot/grub/grub.conf. Finally, reboot the node. Once it restarts, the acpi=on command is effective.
