DUAL BOOT COMPUTER SYSTEM

摘要

A system of booting a computer in which a pair of boots (or dual boots) is provided in the flash memory of the computer. The first flash boot, also called the primary boot, is activated when the computer is turned on, after the POST (Power on Self-Test). The primary boot determines if a secondary boot is stored in the flash memory of the computer. If the secondary boot is not stored in the flash memory of the computer, the primary boot resumes and the computer is booted using the primary boot. If a secondary boot is stored in the flash memory of the computer, the primary boot resumes and is completed, after which the computer is reset and rebooted using the secondary boot.
