ROM is the Flash memory. But how the booting process take the instructions from ROM BIOS.

A ROM-BIOS is an abbreviation of Read Only Memory Basic Input Output System. In PC's the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions.

The BIOS is typically placed in a ROM chip that comes with the computer. This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing.

BIOS is the fist stage after turning on computer it is also called THE FIRMWARE.

Hey! Kishore ROM is not fresh memory but it is dead memory of a computer that's why computer use BIOS to boot up!

ROM is flash or permanent memory where our BIOS system is stored. So, when our computer starts ROM loads the BIOS first to check whether our system I/O is properly connected or not.

When you power on the CPU it perform the post function, so this operation start from the BOIS. But all the chips in motherboard is maintained the BIOS operations.

1st start a computer and open bios setting, ROM bios setting you show instructions available on boot up.

Yes BIOS is the first stage booting device so while system turning on or restart computer.

It's a program which resides in the computer ROM or EPROM that is automatically executed by the processor when the computer turned on.

Why ROM is called flash memory?

Afzal said: (Dec 1, 2016)  
Bios is the main part of the system, Bios locate in ram memory without bios we cannot start OS.

Kurt said: (Feb 12, 2018)  
Bios ver. RL86510A.86.0089.P21 support COM1, only. Is it possible to get support to COM2 and COM3 via a PCI serial card?

Please anyone give details.

How to restore the BIOS in PC? Please tell me.

ROM is a Flash Memory. It's the extension for Read Only Memory.

BIOS is work for Physical hardware Basic Input Output System.

Laya Madhuri said: (Aug 14, 2019)  
BIOS is embedded in ROM, and booting information store in rom and first time start the computer so bootstrap loader initiate and take up OPERATING SYSTEM from hard disk to RAM. And POST operation execute this time, post operation function to check system activity and efficiency.
