In some embodiments, the invention involves a system and method to enable a mobile device to utilize self-clocking during boot. In at least one embodiment, a platform has at least one processor core coupled to an internal timer. For an X86 processor, the internal timer may reside in an advanced programmable interrupt controller. A boot kernel executing on the platform is configured to use the internal timer early in the boot phase, when the platform is not compliant with legacy PC/AT architecture. If the platform does conform to the legacy architecture, then the boot may use an external clock for timing and clocking early in boot. In both cases, the internal timer is calibrated to the external clock before completing the boot phase. Other embodiments are described and claimed.
