Abstract
In some embodiments, a method, apparatus and system for disk caching in a dual boot environment are presented. In this regard, a caching agent is introduced to, responsive to a system boot, read a location in non-volatile memory to determine whether a previous system boot was made into an operating system that does not support disk caching. Other embodiments are also disclosed and claimed.
Claims22
A method comprising:
- responsive to a system boot, reading a location in memory to determine whether a previous system boot was made into an operating system that supports disk caching.
An electronic appliance, comprising:
- a processor;
- a cache memory coupled with the processor to store data needed for the launch of an application;
- a storage device coupled with the cache memory;
- and
- a caching engine coupled with cache memory, the caching engine to, responsive to a system boot, read a location in memory to determine whether a previous system boot was made into an operating system that supports disk caching.
A storage medium comprising content which, when executed by an accessing machine, causes the accessing machine to read a flag in memory to determine whether a previous system boot was made into an operating system that does not support disk caching and to invalidate a disk cache if the flag is clear.
An apparatus, comprising:
- cache memory;
- a bus interface;
- and
- control logic coupled with the bus interface and the cache memory, the control logic to read a flag in the cache memory to determine whether a previous system boot was made into an operating system that does not support disk caching.
Dependencies are inferred from the claim text.
