摘要：PURPOSE: A computer security system is provided to enhance security of a computer system by a detachable password module(60) and a password checking program. CONSTITUTION: A password module(60) is connected to an I/O(Input Output) controller(50) of a computer through a serial or parallel port of the computer and comprises a non-volatile memory(62) storing a user's password. A BIOS(Basic Input Output System) ROM(40) contains a boot block for the system booting and a main block storing BIOS program code. The boot block is read only area and has a password checking routine in its block. A RTC(Real Time Clock)(20) comprises a CMOS RAM(22) storing data for computer system configuration and password setting and a battery(30) for power supply to the CMOS RAM(22). When the user connects the password module(60) to the port of the computer and turns on the computer, the password checking routine in the BIOS ROM(40) is executed by a CPU(10) of the computer before booting. If the password inputted by the user and the password stored in the password module(60) is same, the computer starts system booting.
