BOOTING AN OPERATING SYSTEM OF A SYSTEM USING A READ AHEAD TECHNIQUE

摘要

In one embodiment, the present invention includes a method for generating a list of files accessed during an operating system (OS) boot process to profile the OS boot process, and optimizing the list of files to generate an optimized file list for use in future OS boot processes, where the optimizing is according to a first optimization technique if the files were accessed from a solid state medium and according to a second optimization technique if the files were accessed from a rotating medium. Other embodiments are described and claimed.

1. A prefetch controller that, in operation, executes machine-readable instructions that cause the at least one processor to:
detect a presence of at least one of: a communicably coupled rotating storage device or a communicably coupled solid state storage device; selectively perform a boot file prefetch responsive to detecting a communicably coupled, bootable, rotating storage device, the first boot file prefetch causing the at least one processor to:
identify at least one file included a boot sequence; andtransfer the at least one identified file from rotating storage device communicably coupled to the at least one processor to a cache memory communicably coupled to the at least one processor prior to execution of the at least one file; and selectively perform a different boot file prefetch responsive to detecting a communicably coupled, bootable, solid state storage device.
