Introduction
The BIOS (Basic Input/Output System) is the software code that first runs when the PC powers on. Its full of everything required to initialize almost all the hardware elements of laptop computer. Normally, once you first turn on laptop computer, the BIOS performs an electrical on Self Test, or POST because it is called. It is a number of diagnostic tests around the RAM along with Hardware. It also initializes the many hardware devices such as the hard drive, memory, video along with hardware, identifies and reserves memory addresses for all you IRQs and ports available on the motherboard, and calls a tiny main system program referred to as boot loader. The boot loader, utilizing the BIOS information amongst other things, starts calling the programs that will load the OS. And lastly, the OS uses the BIOS information to take treatments for tough ware devices.
Mother board manufactures use the BIOS to define settings with the various hardware components like the hard drive, RAM, CD-RAMs, I/O ports etc. These are generally set at the factory and therefore are what is called the Factory Settings or even the BIOS Setup Default Settings.
The BIOS software code and all the settings with the PC are stored with a memory chip that’s continuously supplied with the ability with a battery. The car battery also powers a real time that keeps accurate times.
Mother board manufactures and BIOS vendors frequently release updates, that is “flashed” to your BIOS. In most troubleshooting cases, your main choices to update the BIOS.
To penetrate the BIOS setup, you should press [Delete], or something similar, if your computer is booting up. Depending on the PC, the main element can be different – [Esc],[F1],[F10]. Etc.
Updating the BIOS along with firmware
Benefiting from the capabilities offered by EEPROM, motherboard manufactures began releasing new versions in the BIOS with greater frequency nowadays. There are many reasons that the update to your BIOS are usually necessary: the revolutionary version offers better stability, compatibility or performance; new technical break thoughts require latest features in the BIOS; a computer connected computer might not function devoid of the newer version; and increasingly, flashes fix some problems in the last form of the BIOS.
Much like the PC motherboard has a BIOS chip, so do other hard ware components and peripherals. These include stuff like it card, the CD-ROM/RW, DVD-ROM/RW,etc. Generally, the BIOSes on they are generally known as firmware. And just as being the PC BIOS may be updated, the BIOS these devices may be updated, too. While we only cover flashing laptop computer BIOS, the procedure is pretty similar for other firmware.
Identify When your BIOS is flashable
The first task would be to identify should you have a flashable BIOS. Peel the sticker away from the BIOS chip and note down the model number. Proceed to the motherboard manufacturer’s Site and appearance with the model and whether it is flashable. When you have determined that you have a flashable BIOS, we’re also operating.
Get the Latest BIOS updates
When you have copied down all of your settings, you need to to spot the latest updates for the BIOS. To do this, visit your motherboard manufacturer’s website and check up BIOS updates for the mother board model, make and number. Download the proper update through the site. Download the flash program that will ‘flash’ the update on to your BIOS chip. Usually, the update plus the flash program is going to be zipped together.
