One problem is the VSA code is executed under the SMM. The SMM i is 16-bit mode by default. Theoretically, we can have a 16-bit to 32-bit switch upon the entry of SMM and port the VSA to 32-bit mode. I am not so sure if it is worth to do this. > Can we port the necessary parts over to protected mode? > > -- > Richard A.
