How to update the BIOS?
Before you ask for the purpose of updating your BIOS, you need to know exactly what kind of BIOS is on your computer. There are a large number of different kinds of BIOS programs that use different information storage systems. Only a BIOS that works by flash memory can be updated without the use of complex programmers. If your BIOS uses flash memory, then you can safely download the program for updating the BIOS on the website of the manufacturer of your computer.
How to find out how the BIOS works on your computer?
- To see and make sure that your BIOS works on the principle of flash memory, you need to remove the computer cover and find it. It differs from other BIOS devices with a graphic sticker with the manufacturer’s inscription.
- Remove the sticker and carefully read the chip label.
- If a window is drawn in the middle of the microcircuit, then your BIOS works on the principle of ultraviolet erasure. It does not suit us.
- If the labeling starts with 27, then this is also not a flash BIOS. The presence of a window in the middle of the marking tells us that we have a device with a permanent memory of electrical erasure.
- In the event that there is no window in the marking, then special attention should be paid to the first numbers in the inscription. If they are 28 or 29, then most likely - this is the flash technology of the chip.
- Now you can attempt to update the BIOS of your computer.
How to update the BIOS on the computer?
- Download the file from the manufacturer's website containing the code for the new BIOS version. We need the website of your motherboard manufacturer. On the manufacturer's website, you can find BIOS identification tables. The table lists the BIOS codes that denote certain models of different chips. In order to find out the BIOS model of your computer, you need to turn off the computer and turn it on again. As a rule, BIOS information appears immediately after turning on the computer. It is an identification string displayed in the lower left corner of the monitor screen. You need to rewrite the information and then compare it with the table on the manufacturer’s website. This way you will know which program you need to update the BIOS.
- Before installing a new BIOS, you need to prepare your computer.
- Restart your computer and start it in safe mode.This is necessary in order to avoid unnecessary failures when the main bus of the computer operates at a high rate.
- Check the Flash BIOS Protection feature. It must be in Disabled mode. Otherwise, the BIOS protection system will work in order to block the update attempt. Some BIOS models require a jumper switch that disables and allows installation of BIOS updates. The location of the jumper can be found in the instructions for your motherboard. After updating the BIOS, the jumper should be returned to its original position in order to avoid damage to the information contained in the BIOS.
- Now to update the BIOS, you need to disable caching of the system BIOS. The option is called System BIOS Cacheable.
- Disable the video BIOS Cacheable cache option.
- Disable all Shadow Memory options.
- Turn off all power management features.
- After the done operations make sure that the computer will be connected to the UNINTERRUPTED power supply system. After all, if during the BIOS update the power is turned off, then all the necessary information to start the computer will be lost. In this case, the computer will not be able to start even in the MS-DOS environment. In fact - this means damage to the entire motherboard, and of the computer as a whole.
- Now you need to download the BIOS update program for your motherboard on the manufacturer’s website and proceed with the update procedure specified during the operation of the program.
