What to Know

For AMI, press Del after power up or F1 or F2. For Award, press Del key or Ctrl+Alt+Esc. See list for others.
As the computer boots, look for the BIOS manufacturer logo or text. Each manufacturer is accessed differently.

This article explains how to access BIOS after you locate the manufacturer name, and what to do if you can't determine the BIOS manufacturer.

How to Access BIOS Setup Utility

BIOS (Basic Input/Output System) is your computer's firmware, the base-level software that helps control your hardware. Accessing BIOS can be necessary at times, and this is usually an easy thing to do. However, if you've tried the basic BIOS access steps and still can't get in, the information here may help you.

The first suggestion is to take a look at one or both of these lists of BIOS access keys:

Every computer's motherboard has a BIOS manufacturer, so if neither of the above resources helps, this list of BIOS access keyboard commands based on the original manufacturer should get you in without a problem.

As your computer boots up, look for one of the following manufacturers to flash on the screen. The name usually appears as a logo in the top-left corner or as text at the very bottom of the screen.

The beep you hear when you first turn on your computer is referred to as the Power On Self Test (POST).

After verifying the creator of the BIOS on your system, reference the information below and use the appropriate keyboard command to access the utility.

Press Del during the POST, immediately after the computer starts.
Many older systems required Ctrl+Alt+Esc, Ctrl+Alt+Ins, or Ctrl+Alt+S.

Trouble Finding Your BIOS Manufacturer

If you haven't found the BIOS manufacturer of your system, and you can't see that information when you reboot, there are a few other methods for finding this information.

One easy method is to use a system information tool. Most of those programs include that information.

Another way to find the BIOS manufacturer is to look in the System Information tool included in Windows. See our guide on checking the current BIOS version for help, which includes the version and the BIOS manufacturer. In that guide, you'll also find some alternative methods for finding out BIOS information, such as using a BIOS update tool or the Windows Registry
