Abstract
A system for initializing hardware of a computer system includes a board support package (BSP) (20) and a ROM monitor (30). The BSP includes: a basic initialization module (21) for initializing a CPU, a Flash, etc.; an advanced initialization module (22) for initializing serial ports, an Ethernet, etc., for configuring parameters related to system operation and an interrupt service program; a function library (23) for storing various functions for performing configuration and modification of parameters of the hardware; and a boot loader (24) for determining whether parameters of the hardware need to be configured, and for booting an operating system or the ROM monitor based on the determination. The ROM monitor includes a command line editor (31) for inputting commands by users, a command translator (32) for translating the commands into computer-readable instructions, and a function invoking module (33) for invoking functions from the function library based on the instructions.
