Usually, these options are found in the "Advanced Chipset Features" menu in the BIOS. However, if they're not there, your BIOS might not support the features. My laptop doesn't have those two either, for example. I'm not really sure of anything that will get you the features apart from upgrading ("flashing") your BIOS... but even then, your motherboard might not actually have the capability... hmmm... so many options... sorry I can't be of much more help.
