Abstract
A disk drive is disclosed comprising a microprocessor, a non-volatile serial semiconductor memory for storing code segments of a control program, a first semiconductor memory for storing code segments of a loader program, and a second semiconductor memory for receiving the code segments of the control program. When the disk drive is powered on, the microprocessor executes the loader program from the first semiconductor memory to load the control program from the non-volatile serial semiconductor memory into the second semiconductor memory. The microprocessor then executes the control program from the second semiconductor memory.
