How update BIOS (flash). El BIOS ("Basic input / output system") is an essential component of the PC, which controls the material elements of the PC. It is a small piece of software in which one part is in ROM (inactive memory, that is, memory that cannot be modified) and another in EEPROM (flash memory modifiable by electrical impulses, hence the term 'flash').

How to update BIOS (flash) easily

The BIOS of the PC is a small memory located in the motherboard whose data defines the system configuration. However, this data may contain errors. However, with the emergence of new materials, BIOS manufacturers can update them.

However, this is not as simple as it seems to be because the BIOS is a memory, which is conserved when the PC is turned off (it would be really unpleasant to reconfigure the BIOS every time we restart the PC…). That is why the BIOS has evolved a few years ago so that we can update it.

Most motherboards contain flash memories, which can be changed directly by the software. BIOS on motherboards with this type of memory can be to update (the term 'updater' is sometimes used comes from the English word 'update'), thanks to a program called firmware, provided by the manufacturer, intended to replace the old BIOS with a newer one.

However, the biggest problem is getting BIOS updates (the problem is now solved thanks to Internet). These updates are available on the motherboard manufacturer's website, like a binary file, that contains a BIOS image and that will be transferred to the flash memory thanks to the firmware.

In summary, the flash BIOS is a software update to the BIOS, that is, a replacement of the previous version, thanks to a program.
