Methods of conserving memory resources available to a computer system during execution of a system BIOS are provided. The method includes (a) executing the system BIOS; (b) loading the header, runtime code, and memory allocator code associated with the option ROM BIOS chip into the option ROM memory space; (c) passing control to the memory allocator code; (d) executing the memory allocator code to allocate conventional memory of the system RAM; (e) copying the decompressor code from the option ROM BIOS chip to the allocated conventional memory; (f) passing control to the decompressor code; (g) executing the decompressor code to decompress the compressed initialization code directly from the option ROM BIOS chip and thus loading the decompressed initialization code into the conventional memory; and (h) executing the decompressed initialization code to initialize the adapter card or controller.
