What Happens If You Boot A PC Without RAM?

If you boot a PC without ram, it’ll be forced to default to using the cache memory, where there is enough space for the system function and IO.

“Cache Memory is a scratch pad storage area which can hold data until it’s needed or permanently discarded. Cache Memory is intended as either semiconductor ports for CPU-memory transactions or as separate physical devices such as with Level 2 (L2) caches.”
