Abstract:
A computer system including no basic input/output system (BIOS) for operating bootstrap used in initial activation of a legacy operation system is allowed to perform booting of legacy operation system therefor and includes a central processing unit (CPU) and a memory, in which extended firmware and bootstrap program are stored. The extended firmware includes BIOS emulator and a plurality of device drivers. The extended firmware uses the device driver to make the BIOS emulator perform emulation of BIOS operation in response to a BIOS call issued by the bootstrap program.
