Abstract

A PCIe switch including a memory and a processor. The processor is operable to receive a transaction from an information handling system to an endpoint device, determine that the transaction is a request to receive firmware code from the endpoint device, block the transaction from being issued to the endpoint device, and provide the firmware code to the information handling system from the memory.

First claim

What is claimed is:

1. A Peripheral Component Interconnect-Express (PCIe) switch comprising:
a memory to store a first base address in an endpoint device, wherein the first base address points to a first location of firmware code in the endpoint device; and
a processor that:
receives a first transaction from a first information handling system to a physical function of an endpoint device;
determines that the first information handling system can not access firmware code from…
