Abstract
A method for accelerating an operating system boot process is disclosed. In one exemplary embodiment, during a first operating system boot, information regarding the physical locations of disk access performed by the operating system to complete the boot are recorded and stored in a control data file. The control data file is used during a second operating system boot to predict which data will be required during the second operating system, and to populate a cache with that data. The cache can then be used to improve the second operating system boot to improve the boot time. In one embodiment, the information is independent of a file system of the operating system. In another embodiment, the cache can be populated by copying data from a mass storage device to a cache, and when the data is used, it can be moved from the cache to another cache.
