These updates can be “flashed” onto the BIOS chip, replacing the BIOS software the computer came with with a new version of the BIOS.
BIOSes are computer-specific (or motherboard-specific), so you will need the BIOS for your exact model of computer (or motherboard) to update your computer’s BIOS.
You won’t get anything out of it except possible new problems.
A motherboard is the main printed circuit board (PCB) in a computer.
Other form factors include extended ATX mini-ATX, micro ATX, BTX, micro BTX mini ITX, micro ITX and nano ITX.
The integration of components has eliminated the Northbridge chips that managed memory from motherboards.
Here are a few cases where updating makes sense: Be sure to check the change log for the BIOS updates and see if they actually have an update you require.
If you are not experiencing any bugs that have been fixed and don’t need the hardware support, don’t bother updating.
Given that you probably will not see any improvements from updating your BIOS, that new bugs could pop up, and the potential for errors while flashing, you shouldn’t update your BIOS unless you have a reason to.
With the advent of memory controllers built into CPU, integrated video too has moved from motherboard to CPU.
On AMD’s new Ryzen, even the Southbridge is optional due to the SOC (system on a chip) nature of the CPU.
Manufacturers often release updates to their computers’ BIOSes.
If you built your own computer, a BIOS update would come from your motherboard vendor.
If your computer is working properly, you probably shouldn’t update your BIOS.
