摘要:
An information handling system may include at least one processor, a memory, and an embedded controller (EC). The information handling system may be configured to, prior to initialization of an operating system of the information handling system: execute memory reference code configured to test selected regions of the memory; transmit results of the memory reference code to the EC; store, at the EC, information indicative of respective likelihoods that particular regions of the memory are bad; and upon a subsequent boot, select a region of the memory having a low likelihood of being bad for loading a Basic Input/Output System (BIOS) of the information handling system.
