Understanding POST and ROM-BIOS service functions. Numerous low-level services are available to real-mode programs (include boot-loaders). Power-On Self-Test (POST). When computer is first turned on, the CPU starts executing instructions in ROM-BIOS Reset-address: CS=0xF000, EIP=0xFFF0

What Is Computer Booting?\n\nComputer Booting In a simple term can be explained as The Process When computer Starts or boots. There are 2 types of booting\n\nCold Booting ::\nWarm Booting ::\nCold Booting :: cold Booting is a process when user start their computer normally like switching on from power socket and hit power button of CPU [Central Processing Unit]\n\nWarm Booting::Warm Booting Is a Process When User Deliberately Restart the System. This can happen when computer Hangs. Or computer system get\'s freeze.\n\nProcess of Computer Booting Using a CD or DVD\nWhen User Start their computer System, the CPU checks itself, which is triggered by clock ticks generated by the system clock. Part of the CPU\'s initialization is to look to the system\'s ROM BIOS. The ROM BIOS stores the first instruction, which is the instructions to run the power-on self test (POST), in a predetermined memory address.
