ABSTRACT:
A computer system employs a process on warm boot which obviates the need to copy code in non-volatile memory to volatile memory; a normal function in a warm boot process. The computer system checks a warm boot flag which indicates that the code was previously copied on cold boot. By avoiding copying this already copied code and executing directly from the volatile memory considerable time is saved. Since BIOS code is typically on the order of 10K bytes, elimination of the necessity to rewrite BIOS and vectoring directly to BIOS image file in RAM saves on the order of ten thousand clock cycles.
