Patent ID: 8516186

Claim:
A method of accelerating access to a primary storage by utilizing an invisible memory area, which is beyond management of an operating system installed in a computer, out of a memory area on the primary storage in the computer, wherein the primary storage includes a first memory area and a second memory area, the first memory area is located in the range of the memory area in which the operating system can provide an address space of maximum capacity, the second memory area is located out of the range of the memory area in which the operating system can provide the address space of maximum capacity, the invisible memory area includes the second memory area at least, and the method comprising the steps of: (a) causing first software that utilizes a portion of the memory area on the primary storage as a RAM disk to receive a user's setting operation for specifying a capacity of the RAM disk; and (b) causing the first software to assign, on a start up of the computer, a continuous region in the invisible memory area as a storage area of the RAM disk having the capacity specified by the user's setting operation, wherein the step (b) causes the first software to change a range of a visible memory area, which is managed by the operating system, out of the first memory area on the primary storage according to the user's specified capacity of the RAM disk received in the step (a) to thereby assign both the second memory area and a portion of the first memory area in the invisible memory area as the storage area of the RAM disk.
