Abstract: This document describes apparatuses and techniques for enabling a user to authorize access to early boot debugging of hardware issues in a computing system. In general, responsive to a user consenting to early boot debugging, a debug reenable signal is set in nonvolatile storage. Upon reinitialization of the computing system and receipt of an early debugging request, if the debug reenable signal is detected and the early debugging request is authenticated, an early boot debugging system is enabled. The user consent to early boot debugging may circumvent the setting of a fuse that otherwise would prevent performance of early boot debugging.

Abstract: The metal ceramic powder with a particle size of 15-45 µm and suitable for thermal spraying is prepared through a combination of mechanical ball milling, spray granulation, and vacuum sintering. The metal ceramic powder is sprayed on a surface of a steel substrate adopting the high velocity oxygen fuel (HVOF) technology with oxygen-propane as fuel and taking oxygen as a combustion improver, propane as fuel, nitrogen as powder feeding carrier gas, and air as a cooling medium to prepare and form the NiCrBSi—ZrB2 composite coating.
