This is where the diagnostic and boot up routines are stored.

Explanation:
Boot-up routines and diagnostic checks have to be available as soon as power is applied, so they live in non-volatile memory that preserves code without power. ROM is designed for this purpose: it stores the firmware that runs first, such as POST and the initial bootstrapping code, and is typically read-only, ensuring the essential startup sequence remains intact every time the system powers on. RAM would lose its contents when power is off, so it can’t hold these routines long-term. While non-volatile options like NVRAM or FLASH can also store firmware, ROM is the traditional and most fitting location described by this scenario. (In modern devices, firmware may reside in flash, but the idea remains the same: non-volatile, startup code loaded early in the boot process.)
