Abstract
A computer system includes a system CPU responsive to a control signal to load a first operating system or a second operating system. The first operating system is run by the computer system in a first operation mode and the second operating system is run by the computer system in a second entertainment mode. A PC operating in an entertainment mode may operate a variety of entertainment software applications. A quick boot process is also provided. The quick boot process may include an accelerated BIOS boot process that defers and delays appropriate tasks. The quick boot process may also include: detecting a condition; performing a BIOS boot process; loading an image file associated with the condition; and executing the image file associated with the condition. The condition may be that associated hardware is unchanged from a previous boot. A parental control system is also disclosed.
