In an embedded system, the boot loader's role is more complicated because these systems rarely have BIOS to perform initial system configuration. Although the low-level initialization of the microprocessor, memory controllers, and other board-specific hardware varies from board to board and CPU to CPU, it must be performed before an OS can execute. As embedded system is heavily dependent on the hardware boot loader, in order to write a generic boot loader, it is very difficult and can only append more processors and operating systems support in the source code.
