Your machine's BIOS isn't tied to your operating system. To access your BIOS settings, you usually have to press a certain key combination when your computer first turns on. Sometimes there is a message at the bottom of the screen saying something like "Press F10 to enter setup". That's how you access you BIOS. The key combination varies greatly. If you don't see it on your initial boot up/memory test screen, then you'll need to pull out your motherboard manual or visit the motherboard's website to find out. If you've got a brand name PC that only displays a logo (like Compaq), then you'll need to visit the company's website to find the information.
