UEFI boot mode OS provisioning system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a Universally Extensible Firmware Interface (UEFI) engine that is configured to:
• boot in a UEFI boot mode;
• load, while in the UEFI boot mode, a portion of a legacy Basic Input/Output System (BIOS) compatibility support module, wherein the portion of the legacy BIOS compatibility support module provides for the configuration of a communication subsystem to communicate with a pre-boot execution environment system via legacy BIOS communications;
• communicate, with the pre-boot execution environment system via the legacy BIOS communications using the communication subsystem and while in the UEFI boot mode, to retrieve UEFI boot information via a remote legacy BIOS boot mode operation;
• and
• install, using the UEFI boot information and while in the UEFI boot mode, an operating system.

A method for providing an operating system on a server device in a Universally Extensible Firmware Interface (UEFI) boot mode, comprising:

• booting, by a computing device, in a UEFI boot mode;
• loading, by the computing device while in the UEFI boot mode, a portion of a legacy Basic Input/Output System (BIOS) compatibility support module, wherein the portion of the legacy BIOS compatibility support module provides for the configuration of a communication subsystem in the computing device to communicate with a pre-boot execution environment system via legacy BIOS communications;
• communicating, by the computing device with the pre-boot execution environment system via the legacy BIOS communications using the communication subsystem and while in the UEFI boot mode, to retrieve UEFI boot information via a remote legacy BIOS boot mode operation;
• and
• installing, by the computing device using the UEFI boot information and while in the UEFI boot mode, an operating system on the computing device.
