SYSTEM AND METHOD FOR MANAGING EXPANSION READ-ONLY MEMORY AND MANAGEMENT HOST THEREOF

摘要

A system and a method for managing an expansion read-only memory (ROM), and a management host thereof are provided. The management host is connected with a computer host through a bridge. The management host establishes an address lookup table to assign a virtual function and an expansion ROM corresponding to the virtual function. When a request is issued by the computer host to obtain a size of the expansion ROM, the management host provides data in a shadow register block corresponding to the expansion ROM to the computer host according to the address lookup table. The computer host assigns a memory block in the computer host to the expansion ROM according to the data in the shadow register block. When another request is issued by the computer host to obtain data of the expansion ROM, the management host provides the data of the expansion ROM to the computer host.

主权项

1. An expansion read-only memory (ROM) management system, comprising:
at least one computer host; and a management host connected with the corresponding at least one computer host respectively through at least one bridge, wherein the management host comprises at least one virtual function and establishes at least one address lookup table to assign the at least one virtual function and at least one expansion ROM corresponding to the at least one virtual function to the at least one computer host, wherein when the at least one computer host issues a request to obtain a size of the at least one expansion ROM of the at least one virtual function, the management host provides data in at least one shadow register block corresponding to the at least one expansion ROM to the at least one computer host according to the at least one address lookup table, the at least one computer host assigns at least one memory block of the at least one computer host to the at least one expansion ROM according to the data in the at least one shadow register block, wherein when the at least one computer host issues a request to obtain data of the at least one expansion ROM through the at least one bridge, the management host provides the data of the at least one expansion ROM to the at least one computer host according to the at least one memory block.
