Introduction

The BIOS (Basic Input/Output System) may be the software code that first runs when the PC powers on. It has the information essential to initialize many the hardware components of laptop. Normally, whenever you activate laptop, the BIOS performs an electrical on Self Test, or POST which is called. This is the series of tests for the RAM along with Hardware. Furthermore, it initializes the many hardware devices like the disk drive, memory, video along with hardware, identifies and reserves memory addresses for all the IRQs and ports located on the motherboard, and calls a compact operating system program called the boot loader. The boot loader, while using BIOS information amongst other considerations, starts calling the programs that could load the OS. And finally, the OS uses the BIOS information to look at treating tough ware devices.

Mother board manufactures use the BIOS to define settings for the various hardware components such as disk drive, RAM, CD-RAMs, I/O ports etc. These are generally set at the factory and so are what is known as the Factory Settings or even the BIOS Setup Default Settings.

The BIOS software code as well as the settings for the PC are stored on the memory chip that’s continuously given the facility by a battery. The battery pack also powers a true time that keeps accurate times.

Mother board manufactures and BIOS vendors frequently release updates, which can be “flashed” towards the BIOS. In a few troubleshooting cases, your only choice is to update the BIOS.

To enter the BIOS setup, you’ll need to press [Delete], or something similar, as soon as your computer is booting up. With regards to the PC, the true secret may be different – [Esc],[F1],[F10]. Etc.

Updating the BIOS along with firmware

Making the most of the capabilities offered by EEPROM, motherboard manufactures started releasing new versions with the BIOS with greater frequency these days. There are many reasons that an update towards the BIOS are usually necessary: the new version offers better stability, compatibility or performance; new technical break thoughts require the latest features from the BIOS; a computer device coupled to the computer might not exactly function minus the newer version; and increasingly, flashes fix some problems in the form of the BIOS.

Just like the PC motherboard includes a BIOS chip, use other hard ware components and peripherals. These include stuff like the video card, the CD-ROM/RW, DVD-ROM/RW,etc. Generally, the BIOSes on they’re referred to as firmware. And merely because the PC BIOS can be updated, the BIOS of these devices can be updated, too. In the end only cover flashing laptop BIOS, the procedure is pretty similar for other firmware.

Identify If the BIOS is flashable

The 1st step is always to identify when you have a flashable BIOS. Peel the sticker over BIOS chip and make a note of the model no .. Proceed to the motherboard manufacturer’s Web site and show off for the model and be it flashable. Once you have determined that you’ve a flashable BIOS, we have been in business.

Find the Latest BIOS updates

Once you have copied down your settings, the next task is to recognize the latest updates to your BIOS. To achieve this, see your motherboard manufacturer’s website and look up BIOS updates to your mother board model, make and number. Download the correct update from the site. Download the flash program that could ‘flash’ the update on your BIOS chip. Usually, the update and also the flash program will likely be zipped together.
