What Is BIOS ?

American Megatrends BIOS, or AMIBIOS as it is commonly known, is one of the most popular BIOS' in the world.

BIOS stands for Basic Input Output System. It is a small piece of software that sits on a chip inside of your computer on its motherboard.

You often hear the BIOS be called: Firmware, System BIOS, CMOS, Flash BIOS, ROM BIOS and RAM BIOS.

The BIOS checks that all the parts inside your computer, e.g. keyboard port, memory, graphics etc., are in working order before your operating system, e.g. Microsoft Windows 7, is loaded.

The initial check that takes place is called the Power On Self Test (POST). When you first switch your computer on, the POST is taking place when you see this screen (or similar):

POST: Power On Self Test

If the POST does not detect any problems, your computer, or laptop, or tablet (etc), will make a short beep noise to let you know your computer passed the POST test.

Your operating system will then start to load using the information provided by the BIOS. The 'Bootstrap Loader Program' does this automatically.

If the POST detects a problem with your hardware, it will beep to let you know. The number of beeps and the subsequent on screen message (unless it is a graphics card issue) will tell you what the problem is.

There are 11 common American Megatrends BIOS beep codes. These are given in the table below, with some suggestions as to what they mean:

1 Beep DRAM Refresh Failure Memory or Motherboard
2 Beeps Memory Parity Error Memory or Motherboard

AMIBIOS BIOS Beep Codes

The PC Guide (Opens New Window) web site has some excellent material on how to troubleshoot AMIBIOS problems.

The information is quite technical. If you are unsure I would advise in this instance to take your machine to a local Small Business Computer Repair shop, or call your computer makers support line.

BIOS Setup

The American Megatrends BIOS Setup Utility provides a lot of details about your computer hardware. You can change some of the settings if you want to, but in most cases you won't need to.

Some details are for information only, which you cannot change.

When you switch on your computer, press the Delete key American Megatrends BIOS Keyboard Delete Key to enter the BIOS Setup Utility.

When you switch on your computer, press the Delete key to enter the BIOS Setup Utility.

There is only a small window of opportunity to do this before your computer starts to load the operating system. Therefore, keep pressing the delete key until the BIOS Setup Utility appears.

On some computers you need to press the F1 or F2 keys on your keyboard to access the BIOS Setup Utility:

AMIBIOS Setup Utility

Your AMIBIOS Version may look different to the image above. However, the menu names (Main, Advanced etc.) and how you move through each option are usually consistent, as shown in the right hand side of the image (Select Screen etc.).

The options in grey are for information only, and cannot be changed e.g. Processor Speed. The options in blue can be changed.

In the image above, you could change the system time and system date if you wish, for example, if you have an AMIBIOS laptop and you moved to another time zone.

You can also setup BIOS passwords in the Security menu so only you and selected members of your family can change the BIOS settings:

Most home computer users do not need to change any of the BIOS settings. Don't worry if some or all of this pages doesn't make too much sense to you. Treat it as information only.

Your bios is really messed up boy so Basically what you need to do is

1.Connect another keyboard to the computer

2.Shut it down and restart the computer

3.Press the delete key immediately after the computer powers on

4. Bios setup will show up. restore it to the default and restart.

Older AMI BIOS could be restored back to bootable settings by pressing and holding the Insert key as the computer is booting.

BIOS or CMOS diskettes

Early 486, 386, and 286 computers required a floppy disk in order to enter the BIOS setup. These diskettes may be referred to as ICU, BBU, or SCU disks. Because these diskettes are unique to your computer manufacturer, you must obtain the diskettes from them. See the computer manufacturers list for contact information.
