UEFI boot mode OS provisioning system
A Universally Extensible Firmware Interface (UEFI) boot mode operating system (OS) provisioning system includes a pre-boot execution environment system coupled to a server device through a network. The server device boots in a UEFI boot mode. While in the UEFI boot mode, the server loads a portion of a legacy Basic Input/Output System (BIOS) compatibility support module. The loading of the portion of the legacy BIOS compatibility support module provides for the configuration of a communication subsystem in the server device to communicate with the pre-boot execution environment system via legacy BIOS communications. The server device then communicates 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 uses the UEFI boot information to install an OS on the server device.
