The BIOS is written
program code named Firmware by the BIOS manufacturer that resides in one or
more chips on the computer motherboard that helps the computers to perform many
primary functions.
BIOS (Basic input/output
system) has important work within your computer system because without BIOS
wouldn’t be any interface/communication between the Central Processing Unit
(CPU) and the other components.
The BIOS, programmed code
named Firmware serves several function within our system some of them are:
Booting the operating system, the BIOS takes up the control of the computer
system and boots the operating system, since the BIOS contains the bootstrap
loader which is responsible for searching and starting the operating system boot
program.
The BIOS also uses the
Power on Self-test to test the computer hardware through performing the memory
test. For instance if your forgotten to replace the RAM on the motherboard the
BIOS POST will uses beeps code to notify you. But the beep codes differ
according to the BIOS you’re using.
Furthermore the BIOS allow
the CPU to access the video controller, hard disk and other peripheral
components through providing low-level hardware access when the operating
system runs.
Point to note is that noting
every motherboard use the same chip set, so this means that not every BIOS can
be the same even if they are from the same manufacturer.
Upgrade the Computer BIOS
You have to upgrade your
BIOS at least every five to six month to prevent the incompatibility problems
otherwise when you will be trying to plug to new gadgets might get discarded by
your computer BIOS. Here are some of the advantages of upgrading your
computer’s BIOS.
Will allow your computer
to support new hardware: As you always know new hardware are released daily as
the technology regards, and might happen that at the time you bought your
computer there were not such hardware built in, so you will need to install to
your computer so that can serves some functionality. This hardware might be
Universal serial bus, additional serial and parallel ports, etc.
Through upgrading your
computer’s BIOS, will allow some BIOS features not related to hardware to fit
on, among of the features are password protection for computer system, built in
virus protection and BIOS settings.
Allows your computer
system to take automatic configuration to the adapters it contains especially
if you upgrade from non-PnP to PnP that’s means will support for plug and play.
Before proceeding in any
steps or doing anything make sure you backed up your BIOS settings, and you
need to have a hard copy ready of your hard disk BIOS settings
Without upgrading BIOS
some hardware might not work properly at all to your computer’s system.
Before replacing your BIOS
you will need to know first what type of BIOS you have and its version. Always
when you start your computer the BIOS manufacturer and version will be
displayed on the display for a few second, so take a look at them.
How to identify BIOS chip on motherboard
The next things you need
to know is the motherboard manufacturer, since when buying the BIOS the
manufacturer or the sellers will ask such kind of question.
To replace the BIOS you
will need to perform the following function: Make sure you have the tool kit
with tools such as chip extractor that will be used to remove the chips, you have
adequate static protection, you will be required to find the old BIOS chips on
the motherboard, correct the BIOS upgrade chip, etc. here are the steps to
replace the BIOS to your computer’s system.
Steps to replace your computer BIOS.
- Shut down your computer
- Unplug the PC adapter from the power outlet in case is connected on
- Use your tool kit to disassemble your computer by removing the PCs cover and place it aside
- Use Anti-static wristband if you have it to discharge your static and slip
- Check for BIOS chip on motherboard usually are located near the left edge of the board forward of the bus slot. Now locate the BIOS chip on the motherboard. If you not familiar with such stuff contact, find help from the expert so that can help you
- Remove adapter cards on the motherboard in the way of the BIOS chip and place them aside in safe place. In removing the adapter cards you will need to disconnect the external cable if any, and leave the internal cables connected to the card and just push the cards out. so that you can make your work much easier in removing the chip. Please make sure as the time you remove adapter card don’t touch in, after pushing the cards out of the way touch at the edge of the card.
- Using flat-bladed screwdriver or chip extractor, take precaution in removing the BIOS chip observe carefully, and don’t use force to remove it. As the time you remove the formal BIOS chip, replace the current BIOS chip immediately.
- In replacing the BIOS chip observe the following tips: make sure the pins on the BIOS chip are straight, now you can install the chip and the last tip take care in aligning the pins (notch on the chip with the notch on the socket).
- Before pushing the chip onto its socket, verify that all the pins are aligned properly otherwise will not work.
- Check to see if the orientations of the chips in their socket are installed correctly, if not try to reinstall correct then proceed.
- Place back/ reinstall the removed adapter cards and the external cables
- Now prove your work to make sure that all the adapter cards, external cables you removed earlier are connected properly.
- Replace back the computer cover, plug on the adapter on the power source/outlet then turn on your computer
- If the BIOS were installed correctly, you will find the system begins to boot. Enter key sequences as required by your BIOS to enter the BIOS setup program.
- Now, it’s your time to enter the settings for hard disk and any primary configuration information, leave the complex settings alone.
- Verify if your system can read the hard disk and boot properly.
- Save the BIOS setup configuration settings and let the system reboot.
Now, I’m sure you will get
your BIOS running into your computer’s systems.
