Patent ID: 7660979

Claim:
A multi-mode computer system, comprising: a storage device comprising a single disk partition, wherein the single disk partition further comprises: a first OS for PC mode; a file system for PC mode; a second OS image for media mode; a file system image for media mode; and a boot program for performing a boot procedure; and a BIOS loading the boot program and executing the boot procedure by: if an instruction for PC mode is received, loading the first OS on the computer system to enable the computer system to operate in PC mode; and if an instruction for media mode is receive, starting the computer system by decompressing and expanding the second OS image to execute a second OS kernel on the computer system, wherein using a Ramdisk technique, the second OS kernel decompresses and expands the file system image for media mode into a system memory to create a file system for media mode in the system memory, generates a mapping relationship between the file system for PC mode and the created file system for media mode in the system memory, and during operation in media mode, stores data generated by an application executed in media mode to the storage device based on the mapping relationship.
