Abstract
A booting procedure can take a long time and typically starts from a lead-in on a main data layer of an optical data disc. A Portable-Blue (PB) disc, a dual boot disc, includes a second data layer (304) from which application specific optical drives can boot directly. The dual boot disc still conforms to the prior art standard for PB for normal applications. The second boot (340) will cut in booting time for a specific application and will make application software small. is in particular relevant for gaming, for portable devices and relative specific applications.
Claims20
An optical data disc comprising
- a first boot area for installing a first operating system for booting the first operating system from the optical disc;
- and
- a different second boot area, for installing a second operating system for booting the second operating system from the optical disc, the second operating system being independent of the first operating system and
- wherein depending on an application the optical data disc is enabled to be booted from one of the first boot area and the second boot area;
- wherein the optical data disc comprises a multi layer disc, and the first boot area resides on a first layer of the optical disc and the second boot area resides on a second layer of the optical data disc.
A data disc, comprising
- a first boot area;
- and
- a second boot area, wherein depending on an application the disc is enabled to be booted from one of the first boot area and the second boot area
- wherein the data disc comprises a multi layer data disc, and wherein the first boot area resides on a first layer of the data disc and the second boot area on a second layer of the data disc.
A system comprising an optical data disc drive,
- wherein the drive is enabled to use an optical data disc comprising a standard boot area for booting a standard operating system installed in the standard boot area and a different application specific boot area for booting an application specific operating system installed in the application specific boot area, the specific operating system being independent of the standard operating system, and
- wherein the drive is enabled to boot from the application specific area, and
- wherein the optical data disc comprises a multi layer disc and the standard boot area resides on a first layer of the optical disc and the application specific boot area resides on a second layer of the optical data disc.
A system comprising a data disc drive, wherein the drive is enabled to use a data disc comprising a standard boot area and an application specific boot area, and wherein the drive is enabled to boot from the application specific area and wherein the drive is enabled to use a data disc comprising a first layer comprising the standard boot area and a second layer comprising the application specific boot area.
An optical data disc comprising
- a first boot area;
- and
- a second boot area,
- wherein in an application specific mount process the optical data disc enables an application specific boot from the second boot area,
- wherein in a non-application specific mount process the optical data disc enables a standard boot from the first boot area,
- wherein the optical data disc comprises a multi layer data disc, and the first boot area resides on a first layer of the optical data disc and the second area resides on a second layer of the optical data disc.
