Instead, it uses a and a chain of bootloaders stored in eMMC. This report clarifies the Switch’s low-level boot process, its security architecture, and why there is no standard "BIOS configuration" for end users.

This boot ROM cannot be modified or updated—it's physically part of the processor. The boot ROM determines which memory chip to use for further boot code and begins loading the first bootloader.

The operating system running on the Nintendo Switch is derived from the Nintendo 3DS operating system but heavily modernized. It is architected around the ARM Cortex-A57 CPU cores found in the NVIDIA Tegra X1 (T210) SoC.
