The ROM device 105 includes read-only memory containing a trusted operating system configuration and associated applications. In the exemplary embodiment, the ROM device 105 has high sequential read times. The RAM device 110 includes volatile memory and is configured to execute the operating system and associated during a boot process. The RAM device 110 is also configured to erase everything in volatile memory thereby clearing all of the data on the RAM device 110, in response to a shutdown or power interruption.
In the exemplary embodiment, the trusted operating system configuration is stored on the ROM device 105. The processor 115 instructs the ROM device 105 to transmit the trusted operating system configuration to a ram-disk stored in the RAM device 110 during the boot process of SCS computer system 100. The RAM device 110 and the processor 115 are configured to execute the operating system from the ram-disk. Therefore, a clean operating system configuration is loaded from a high integrity storage device (ROM device 105) to a high-performance storage device (RAM device 110). The SCS computer system 100 is configured to automatically load the trusted operating system configuration during the boot process, without the need for user intervention or monitoring, and with reduced processing time.
