In some cases, technical documentation on this subject is <a href="/wiki/Non-disclosure_agreement" title="Non-disclosure agreement">NDA</a> restricted or unavailable. RAM initialization is particularly difficult because before the RAM is initialized it cannot be used. Therefore, to initialize DRAM controllers and DRAM, the initialization code may have only the CPU's <a href="/wiki/Processor_register" title="Processor register">general purpose registers</a> or Cache-as-RAM as temporary storage. </p><p>romcc, a <a href="/wiki/C_(programming_language)" title="C (programming language)">C</a> <a href="/wiki/Compiler" title="Compiler">compiler</a> that uses registers instead of RAM, eases the task.

Also, the Cache-as-RAM mode initialization is specific to CPU architectures, thus more generic than DRAM initialization, which is specific to each chipset and mainboard. </p><p>For most modern x86 platforms, closed source binary-only components provided by the vendor are used for DRAM setup. For Intel systems, FSP-M is required, while AMD has no current support.
