Abstract:
1. A method to manage memory access, comprising: executing instructions associated with a basic input output system (BIOS) to: detect a memory relocation process in a pre-boot environment prior to initializing a memory device, wherein the memory relocation process comprises allocating a memory block in conventional memory space and initializing an extended BIOS data area in the memory block; disable memory access to the extended BIOS data area in response to detecting the memory relocation process; determine an absolute address value associated with the memory block; store the absolute address value in a peripheral hardware device configured to access the conventional memory; write first memory contents from a second memory block in the conventional memory space to the memory block; write second memory contents associated with a second peripheral hardware device to the second memory block; and store a second absolute address value associated with the second memory block in the second peripheral hardware device.
