A method for upgrading a computer operating system of a computer system, for example, a communications receiver includes a main processor, a slave processor, a first memory, and a second memory, wherein an existing operating system resides in the first memory. The first memory is attached to the main processor and the second memory is attached to the slave processor. The method comprises the steps of receiving a new operating system in the second memory; erasing the existing operating system from the first memory; and loading the new operating system into the first memory. In a communications receiver such as a satellite business receiver for receiving and decoding video, audio and data bitstreams, the first memory may be FLASH memory and the second memory may be cache memory of a video processor, and, more particularly, a video random access memory. |
