Abstract

An information handling system may include a processor, a network interface, and a basic input/output system (BIOS) configured to execute a pre-boot environment. The information handling system may be configured to: during execution of the pre-boot environment, establish a pre-boot network connection to a remote information handling system via the network interface; receive operating system data from the remote information handling system; create a pseudo-device at a specified address of the information handling system; perform direct memory access (DMA) remapping between the pseudo-device and an address range of memory of the information handling system to create a ram disk; and based on the operating system data received from the remote information handling system, initialize an operating system on the ram disk via the specified address of the pseudo-device.
