ABSTRACT:
A method for improving the load time of code and data descriptors is provided. The invention utilizes hardware validation logic for code and data descriptors, but uses a software program to validate system descriptors. In those instances where the descriptor being loaded is a code or data descriptor, system validation checks are not performed. This allows code and data descriptors to be validated and stored into a segment register much faster than if system validation checks were also performed. If the descriptor is found invalid by the hardware validation logic, a branch is made to a software program which is used to determine whether the descriptor is invalid, or is actually a system descriptor. If it is a system descriptor, then system descriptor validation checks are performed by a software program.
