EVASION OF POWER ON SELF TEST DURING AN OPERATING SYSTEM INITIATED REBOOT
First Claim
1. A method for optimizing reboot process of a computer, comprising:
- determining a status of a power on self test (POST) performed during a prior booting of the computer when an operating system (OS) initiated rebooting of the computer is triggered;
loading information obtained during the POST of the prior booting of the computer into a basic input output system (BIOS) of the computer if the status of the POST performed during the prior booting of the computer indicates a success of the POST; and
performing the rebooting of the computer using the information, wherein a subsequent POST associated with the rebooting of the computer is skipped during the rebooting of the computer.

Abstract
A system and method to evade the power on self test during an operating system initiated reboot is disclosed. In one embodiment, a method for optimizing reboot process of a computer includes determining a status of a power on self test (POST) performed during a prior booting of the computer when an operating system (OS) initiated rebooting of the computer is triggered, loading information obtained during the POST of the prior booting of the computer into a basic input output system (BIOS) of the computer if the status of the POST performed during the prior booting of the computer indicates a success of the POST, and performing the rebooting of the computer using the information, wherein a subsequent POST associated with the rebooting of the computer is skipped during the rebooting of the computer.

15. A computer readable medium for optimizing reboot process of a computer having instructions that, when executed by a computer, cause the computer to perform a method comprising:
-
determining a status of a power on self test (POST) performed during a previous booting of the computer when an operating system (OS) initiated rebooting of the computer is triggered; loading information obtained during the POST of the previous booting of the computer into a basic input output system (BIOS) of the computer of the POST; and rebooting the computer using the information and skipping a subsequent POST associated with the rebooting of the computer.
