When updating bios what is important c validating business rules
Most BIOS implementations are specifically designed to work with a particular computer or motherboard model, by interfacing with various devices that make up the complementary system chipset.
Originally, BIOS firmware was stored in a ROM chip on the PC motherboard.
A modern Wintel-compatible computer provides a setup routine essentially unchanged in nature from the ROM-resident BIOS setup utilities of the late 1990s; the user can configure hardware options using the keyboard and video display.
Also, when errors occur at boot time, a modern BIOS usually displays user-friendly error messages, often presented as pop-up boxes in a TUI style, and offers to enter the BIOS setup utility or to ignore the error and proceed if possible.
-oss; an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS) is non-volatile firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs.
In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.
This allows easy, end-user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits.
The BIOS firmware comes pre-installed on a personal computer's system board, and it is the first software to run when powered on.
The name originates from the Basic Input/Output System used in the CP/M operating system in 1975.
