This means that the system is accessible but is not dynamically written to the way that a computer's hard drive is during operation.
A battery on the motherboard keeps the data on it intact, even when the computer is turned off while not in use.
If errors are detected during the test, the computer gives a code that reveals the problem.
Error codes are typically presented as a series of beeps heard shortly after startup.
Probably not, but in this article I’ll walk you through the process of determining whether or not there is an update for your BIOS or UEFI firmware and whether or not you need to install it.
Just because there is an update for your BIOS does not mean that you should necessarily install it.
If you bought a computer from Dell, HP, etc, you normally just have to download an EXE file and run it to flash the BIOS.
If you built your own computer, you will either need to download a BIOS update program from your motherboard manufacturer or you will need to manually perform the flash, which normally entails using a USB stick and booting into DOS.Unlike the operating system, the BIOS is low-level software that is stored on a chip on the motherboard of the computer.In order to update this low-level software, you normally have to “flash the BIOS“, which will replace the old software with the new version.Functions and control over hardware within the computer are then handed over to the OS and it controls the system afterward.Traditional BIOS firmware is included on a computer motherboard as Read Only Memory (ROM).PC users can make certain adjustments to the system through a configuration screen on the computer.
