The first thing to do is turn off the computer if it is on. Once the computer is off, the user will need to turn it back on. Depending on the equipment used in the computer and the age of the computer and BIOS firmware on the machine, the user will need to do the following after the Power On Self Test:
Accessing the BIOS is necessary for a wide variety of situations and can be done with the correct combination of keys that allow access with the computer system that is in use. If the computer is a modern day option, the first screen that is shown will be the OEM (Original Equipment Manufacturer) logo which may have a small note available on how to access the BIOS for the system. If there is no note, pressing the “ESC” key should make it possible to access the boot up information (which usually moves very fast) which will usually explain how to access the BIOS. If this is too fast, pressing the “pause/break” button on the keyboard should stop or slow down the information from scrolling.
The information to look for to learn the BIOS key combination are usually found in lines during the process which will mention something similar to the following:
Note: Where “___” represents the key(s) which must be pressed to enter the BIOS setup.
If both of these options leave the user without information on how to load into the BIOS, then they will need to try using the following Supplier or Vendor codes to access the BIOS.
BIOS Supplier Codes
The BIOS suppliers have their own built in codes which can be used to access the BIOS setup. There are several BIOS suppliers available but the most common options are through:
Advanced Logic Research (ALR) – The BIOS access codes are “F2? or “Ctrl+Alt+Esc”.
Advanced Micro Devices (AMD) – The BIOS access code is “F1?.
American Megatrends (AMI) – The BIOS access code is “Del”.
Award BIOS – The BIOS access codes are “Del” or “Ctrl+Alt+Esc”.
Datatech Enterprises (DTK) – The BIOS access codes are “Ctrl+Alt+Esc”.
Pheonix BIOS – The BIOS access codes are “Ctrl+Alt+Ins” or “Ctrl+Alt+S”.
These are the usual BIOS Access codes which are available on computer systems which were not built by an OEM for resale to consumers. If the computer system is made for consumers to purchase later on by a vendor then they may need to use a separate key combination.
Computer Vendor BIOS Codes
Every computer manufacturer will want to have the BIOS customized to work with the hardware and software that they provide in the system. They will usually generalize the keyboard commands with their systems as well to make it possible to provide faster telecommute based customer support. These are the most common codes used by the following vendors:
Acer - The BIOS access codes are “F1?, “F2? or “Ctrl+Alt+Esc”.
ARI - The BIOS access codes are “Ctrl+Alt+Esc” or “Ctrl+Alt+Del”.
AST - The BIOS access codes are “Ctrl+Alt+Esc” or “Ctrl+Alt+Del”.
Compaq - The BIOS access code is “F10?.
CompUSA - The BIOS access code is “Del”
Cybermax - The BIOS access code is “Esc”
Dell - The BIOS access codes are “F1?, “F2?, “F3?, “F10?, “F12?, “Del” or “Fn+F1? on laptops.
eMachines - The BIOS access codes are “Del” or “F2?.
Gateway - The BIOS access codes are “F1? or “F2?.
Hewlett-Packard (HP) – The BIOS access codes are “F1?, “F2? or “Esc”.
IBM - The BIOS access codes are “F1?, “Ctrl+Alt+Ins” or “Ctrl+Alt+Del”.
Intel - The BIOS access code is “Del”
Lenovo – The BIOS access codes are “F1?, “F2?, “Ctrl+Alt+F3?, or “Ctrl+Alt+Ins”.
Micron – The BIOS access codes are “F1?, “F2? or “Del”.
Packard Bell – The BIOS access codes are “F1?, “F2? or “Del”.
Seanix – The BIOS access code is “Del”.
Sony – The BIOS access codes are “F2?, “F3? or “Del”.
Toshiba – The BIOS access codes are “F1?, “F2? or “Esc”.
Note: Some BIOS setups will be password protected. This is due to the fact that an administrator placed a BIOS password on the system to restrict access to the BIOS through the default BIOS setup screen. Either contacting the administrator or finding a workaround to the password is necessary.
