Abstract
A fast speed computer system power-on & power-off method, that is used to reduce an amount of main memory transferred and stored from a main memory into a second storage device, thus speeding up a speed of re-activation of a computer system from a hibernation state into a full speed operation state. Said fast speed computer system power-on & power-off method is applicable to various types of computer systems, and can be used to write in and load back data in cooperation with a random access processing technology. In addition, said method can be used to reduce extent of data loss and damage of said computer system due to a sudden power outage of said computer system.
Claims9
A fast speed computer system power-on & power-off method, comprising the following steps:
- when a computer system enters into a hibernation, said computer system partitions a main memory into a plurality of clean pages and a plurality of dirty pages, said clean pages are swapped out without I/O access, and said dirty pages are written into a hibernation file and are stored in a swap space and a file system of at least a second storage device;
- when said computer system is re-activated, said computer system reads said hibernation file from said swapped space and said file system, and restores and stores said hibernation file into said main memory;
- and
- said computer system reads data from said second storage device, and loads said data into said main memory.
