At the factory, a minimal version of the Switch OS is installed. A modified version of the boot2 title (boot2.manuBoot) is installed that launches an additional "Manu" sysmodule, and the system config title specifies to launch "Test Application Launcher" instead of qlaunch.
Test Application Launcher is used to launch a number of tests, "CAL0" calibration data is written to NAND, and retail firmware is installed.
Factory firmware contains a stripped down version of the Switch's OS with unnecessary titles removed, and a number of additional debug titles installed. The version of the OS installed at the factory is receiving updates as new switches are manufactured. At least four revisions of factory firmware are known to have been used in production.
- The following system data archive titles are present in retail firmware, but not installed at the factory: 0100000000000801, 0100000000000803, 0100000000000804, 0100000000000805, 0100000000000808, 010000000000080A, 010000000000080B, 010000000000080C, 010000000000080D, 010000000000081A, 010000000000081B, 010000000000081E.
