Suggestions to access BIOS in Windows® XP®
What are the main roles of BIOS in a system?
One of the most important uses of flash memory in the system is for the BIOS or the basic input/output system. On virtually every system available, the BIOS makes sure all the other chips, hard drives, ports, and CPU function together. The BIOS in the system does various functions. When you turn on your system and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere. The BIOS holds a number of hardware configuration options that could be changed through the setup utility. By saving these changes and restarting the system applies the changes to the BIOS and alters the way the BIOS instructs the hardware to function.
Discussed below is the role of the BIOS and the various suggestions to access it in a Windows XP system:

One of the most important roles of BIOS is to boot up the system. When the system is first turned on, its main system memory is empty and it needs to find instructions immediately to decide the main processes that are to be started with the system start up. You can find them within the BIOS program because the BIOS is in read-only permanent memory and so is always available for use, even when the rest of the system memory is empty. This allows the Operating System to start properly and also to communicate with the other hardware devices in the system.
Change the BIOS parameters
Despite its many functions and the important role it plays in running your system, the system BIOS is well-known in the helping provided for changing the settings in it, the little built-in utility that allows you set the many functions that control how your system works. Boot order changing is the most common change that the users make. The BIOS will vary, based on the motherboard in your system. You can simply adjust the settings in BIOS. For doing this, you need to restart the system by pressing the 'F2' key in the system. This will be changed in different systems. You can change the settings in that opening window.
The access method of the BIOS will vary according to the system. This depends upon the system manufacturer. Most of the systems use the 'F2' key to open the BIOS in the system. Unlike the new computers, old systems have many choices to enter in to the BIOS. CTRL+ALT+ESC, CTRL+LAT+INS, CTRL+ALT+ENTER etc. are some of the ways to access BIOS.
