All About Your Computer’s BIOS & Upgrading The BIOS
BIOS in the computer language stands for Basic Input/ Output System. It is the main integral part of a computer that helps it to start up with all the programming. It is a built-in software that helps us to determine what a computer can do without the assessment of programs from a disk.
The BIOS contains in it all the codes that are required to run and control the keyboard, mouse, screen display, hard drive, and the numerous functions that the computer can function. In other words, we can say that the whole computer is dependent on it and does all the functions through it. The BIOS is usually placed in a ROM chip that comes with a computer in the central processing unit. It helps the computer to boot itself. BIOS is known as the third software after the operating system and the other applications, it helps the computer to operate successfully.
Are you confused by the computer BIOS?
First up, let’s just define what the BIOS is. The BIOS stands for the Basic Input-Output System of a PC. It is stored on a BIOS chip on the motherboard and it is the interface between your operating system and the computer’s hardware. All the software actions you make, e.g. click a in Windows XP, are translated into machine instructions which pass through the BIOS and then subsequently to your monitor, graphics card and what not.
The BIOS is a crucial component of a PC If it fails, your PC isn’t going to boot up. I always skip a heartbeat if I see any funny behavior with a PC’s BIOS. Because it spells (almost certainly that is) doom for the computer. Make sure you’re very, very careful if you intend to fiddle around with the BIOS in anyway. Children, don’t do this at home without the supervision of a technie.
In the basic menu in the BIOS, you should see settings for configuring hard drives and boot up options. You can specify which are your primary and secondary hard risk and which will boot up first. You can also specify if the floppy disk or CD Rom boot support before or after the hard disk.
If you go in to the Advanced Options menu, you can delve into the advanced options for the BIOS configuration. If you’re into overclocking, you can specify a different CPU frequency than the default. But be very careful when you do this — you may end up burning your CPU chip if you don’t know what you’re doing.
In the advanced options menu, you can also change memory frequency and timing, as well as the AGP speed for your graphics card. Again, exercise extreme care when playing around with these settings. You can damage your PC if you don’t know what you’re doing.
There are many other options in a computer’s BIOS you can play with. Some of them include password and security options to limit access to the system, or stuff like power saving options. You can also control things like whether the Numlock key should be on or off when you first start the system.
I hope the article has helped you understand a little of what goes into a computer’s BIOS and how you can make use of it. Remember, the BIOS is such a fundamental component of any PC that you MUST exercise extreme caution when meddling with it. If you’re not sure — don’t change anything. It’s best to understand the BIOS properly from an expert or read a good book before changing it in any way.
