BOOT FOR OPERATING SYSTEM OF SYSTEM, PREFETCH CONTROLLER, METHOD, STORAGE DEVICE, BOOT FILE PREFETCH SYSTEM, PROGRAM, AND COMPUTER READABLE RECORD MEDIUM IMPLEMENTED USING READ AHEAD TECHNIQUE

摘要

PROBLEM TO BE SOLVED: To reduce time required for booting a system.;SOLUTION: A method includes the steps of: generating a list of files accessed during an operating system boot process (OS boot process) (120); and profiling the OS boot process to optimize the list of the files and generating an optimized file list used in a following OS boot process (130). Optimization is performed according to a first optimization technique if the files were accessed from a solid state medium and performed according to a second optimization technique, such as rotation wait minimization and a read ahead technique, if the files were accessed from a rotating medium.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
