Boot sequence of legacy BIOS with MBR formated storage media (eg. hard
drive with formated MBR partition structures); 1) BIOS looks for MBR
activate partition, 2) BIOS then looks for executable boot code, for
example DOS IO.SYS/MSDOS.SYS, FreeDOS FDCONFIG.SYS/CONFIG.SYS, are then
loaded into memory and executed.

A decent DOS start execution process explanation can be found here:

As for Rockbox, Rockbox hooks into the OEM firmware/bootloader loading
process.
