Detailed explanation-1: -ROM is located on a BIOS chip which is plugged into the motherboard. ROM is a type of memory circuitry that holds the computer’s startup routine. The ROM BIOS tells the computer how to access the hard disk, find the operating system, and load it into RAM.
Detailed explanation-2: -The BIOS is actually stored in read only memory (ROM). So, the bootloader program opens or wakes up the BIOS, which then finds the complete loading instructions on a bootable device, typically the hard disk. BIOS is low-level system software that boots before your operating system when you start your computer.
Detailed explanation-3: -The boot ROM is a type of ROM that is used for booting a computer system.
Detailed explanation-4: -Booting is the process which is initiated once the computer system starts and executes small set of instructions present in the ROM which will setup system hardware by testing them and load the operating system so that computer system can carry out further tasks.
