Abstract
A method includes a service processor of an information handling system downloading code, including device drivers, and transferring the code to an operating system of the information handling system without rebooting the operating system. In some embodiments, a daemon of the operating system may request device drivers for newly-inserted devices and the service processor may make the device drivers available to the operating system in response to the requests. In some embodiments, the service processor may download updated device drivers and may inform the daemon. The updated device drivers may be automatically provided to the operating system or made available upon a request of a user. The service processor may make code available to the operating system by exposing a portion of its non-volatile memory to the operating system as a virtual device.
