A computer having a peripheral device emulator capable of emulating peripheral devices, thereby allowing a mouse to be physically connected to the computer system and function normally despite not being initialized at the time of system startup or reset. The peripheral device emulator, implemented in the computer system's keyboard controller, operates in conjunction with a password lock mode and also operates at the time of system startup or reset. The peripheral device emulator accepts commands, status requests, and other control signals directed from the CPU and responds appropriately. Initialization commands sent from the CPU are stored for transfer to the emulated peripheral device when the device is physically connected to the computer system. |
