Method for dual FWH ASICS and multi-boot BIOS operations

Disclosed is a method for dual firmware hub (FWH) application specific integrated circuits (ASICs) and multi-boot BIOS operations. Benefits include improved functionality and improved usability.

Background

        � � � � � Conventional designs feature only one FWH per platform. The conventional BIOS supports standard, nominal settings. However, requirements exist for a performance BIOS that features aggressive memory settings and options such as altering the performance of the clock generator. A requirement also exists for a back-up device in the event that the primary FWH image becomes corrupt or damaged. No conventional solution exists to meet these requirements.

Description

        � � � � � The disclosed method is a dual FWH system that enables the user to designate the hub used for the boot operation (see Figure 1). Note: Only one firmware hub reset control channel is shown. This circuit precedes the reset functionality for FWH1.

� � � � � The FWH hub reset is controlled via a signal, GPIO_EN. The FWH_RESET signal and signal states are describe in a table (see Figure 2).

        � � � � � The disclosed method can provide feature and performance enhancements for specialized and high-end desktop platforms. The method may also be used for a more feature rich, user friendly system that includes a means to safely recover the complementary metal oxide semiconductor images if they become unusable.

Advantages
