Systems and methods for accelerated loading of operating systems and application programs
DC CAFCFirst Claim
1. A method comprising:
- maintaining a list of boot data used for booting a computer system, wherein at least a portion of said boot data is compressed by a data compression engine to provide said at least a portion of said boot data in compressed form, and stored in compressed form on a boot device;
initializing a central processing unit of said computer system;
preloading said at least a portion of said boot data in compressed form from said boot device to a memory;
accessing and decompressing said at least a portion of said boot data in said compressed form from said memory; and
utilizing said decompressed at least a portion of said boot data to boot said computer system, wherein said at least a portion of said boot data is decompressed by said data compression engine.

Abstract
Systems and methods are disclosed for providing accelerated loading of operating system and application programs. In one aspect, a method for providing accelerated loading of an operating system comprises the steps of: maintaining a list of boot data; preloading the boot data upon initialization of the computer system; and servicing requests for boot data from the computer system using the preloaded boot data. In a preferred embodiment, the boot data is retrieved from a boot device and stored in a cache memory device. In another aspect, a method for accelerated loading of an operating system comprises updating the list of boot data during the boot process, wherein updating comprises adding to the list any boot data requested by the computer system not previously stored in the list and/or removing from the list any boot data previously stored in the list and not requested by the computer system.

11. A system comprising:
-
a processor; a memory; and a non-volatile memory device for storing logic code associated with the processor, wherein said logic code comprises instructions executable by the processor for maintaining a list of boot data used for booting the host system, at least a portion of said boot data is stored in compressed form in said non-volatile memory device, said at least a portion of said boot data in compressed form is preloaded into said memory, and said preloaded at least a portion of boot data in compressed form is decompressed and utilized to boot said computer system; and a data compression engine for providing said at least a portion of said boot data in compressed form by compressing said at least a portion of said boot data and decompressing said at least a portion of said boot data in compressed form to provide said decompressed at least a portion of boot data. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of preloading an operating system for booting a computer system comprising:
-
storing substantially all of the operating system in compressed form on a boot device; preloading a first portion of the substantially all of the operating system from said boot device to a memory; accessing and decompressing the first portion from the memory using a data compression engine; utilizing the decompressed first portion to partially boot said computer system; responsive to a request, locating a second portion of the substantially all of the operating system using a boot data list and preloading the second portion from the boot device to the memory; accessing and decompressing the second portion from the memory using the data compression engine; and utilizing the decompressed second portion to further partially boot said computer system. - View Dependent Claims (19, 20, 21, 22, 23, 24)
