Abstract:
A method of generating a boot image for fast booting an image forming apparatus. In the method, a boot image is generated to contain information regarding a system state after processes that are not used to execute an operating system and at least one application are terminated. Then, the image forming apparatus is fast booted using the boot image.
Abstract:
An image forming apparatus for updating a boot image for fast booting includes an interface unit to receive a new version of firmware to update a previous version of firmware installed in the image forming apparatus, a non-volatile memory to store a first boot image that is a previous version for the fast booting, and a processor updating a boot image by controlling the stored first boot image to be replaced with a second boot image that is a new version when the received new version of firmware includes the second boot image.
Abstract:
A method of fixing an error of a boot image for fast booting an image forming apparatus. In the method, if a boot image stored in the image forming apparatus has an error, the boot image is deleted, and the error is fixed by replacing the boot image with a backup of the boot image or generating a new boot image.
