Boot ROM: Operation, Specific implementations & Purpose

Boot ROM is a piece of read-only memory (ROM) that is used for booting a computer system. It contains instructions that are run after the CPU is reset to the reset vector, and it typically loads a bootloader. There are two types of boot ROM: a mask boot ROM that cannot be changed afterwards, and a writable boot ROM such as an EEPROM or a flash memory chip.
