本发明涉及一种电脑系统，尤其是指一种设有可载入式基本输出入系统的电脑系统。The invention relates to a computer system, in particular to a computer system equipped with a loadable basic input/output system.

在传统电脑系统中，基本输出入系统(BIOS)是存储在一个只读存储器(ROM)中。由于电脑系统日趋复杂，周边装置日趋多样化，使得基本输出入系统所需的只读存储器空间急速增加。虽然只读存储器的容量也会增加，但是硬体容量增加的速度往往赶不上基本输出入系统的成长速度。In conventional computer systems, the basic input-output system (BIOS) is stored in a read-only memory (ROM). Due to the increasing complexity of computer systems and the diversification of peripheral devices, the ROM space required by the BIOS increases rapidly. Although the capacity of the read-only memory will also increase, the speed at which the hardware capacity increases often cannot catch up with the growth rate of the basic input and output system.

因此本发明的主要目的在于提供一种设有可载入式基本输出入系统的电脑系统，其可将基本输出入系统分为第一基本输出入系统及第二基本输出入系统，其中第一基本输出入系统是存储在一个可存取式存储器中，只在需要时才载入主存储器内，而仅有第二基本输出入系统存储在只读存储器中，因此可以省下大量的只读存储器空间。Therefore, the main purpose of the present invention is to provide a computer system with a loadable BIOS, which can divide the BIOS into a first BIOS and a second BIOS, wherein the first The BIOS is stored in an accessible memory and loaded into the main memory only when needed, while only the second BIOS is stored in the ROM, thus saving a lot of ROM memory space.
