What is cold booting and warm booting in detail?

A warm boot, accomplished by pressing the CTRL+ALT+DEL key combination, restarts the computer through the INT19h ROM BIOS routine. This warm-boot procedure usually does not go through the complete boot process; generally, it skips the power-on self test (POST) to save time. In addition, a warm boot frequently fails to reset all adapters in the computer's adapter slots. If you use the Reset button to cold boot the computer, it generally restarts the boot process, including the POST. However, this procedure does not necessarily discontinue power to the motherboard. If the power is not interrupted, the cold boot may fail to reset all adapters in the computer's adapter slots.
