Abstract

Described is a system where memory can be allocated for use by an adapter pre-boot and preserved for use post-boot. A BIOS can allocate for pre-boot hardware operations (e.g., graphics drivers, framebuffers, etc.) and mark this allocated memory as preserved. An indication of the allocated memory can be provided for an OS, such that post-boot, the OS can reclaim and reallocate this memory.
