    • 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.
    • 具有能够模拟外围设备的外围设备仿真器的计算机,从而允许鼠标物理连接到计算机系统并正常工作,尽管在系统启动或复位时没有被初始化。 在计算机系统的键盘控制器中实现的外围设备仿真器与密码锁定模式一起运行,并且在系统启动或复位时也运行。 外围设备仿真器接受来自CPU指令的命令,状态请求和其他控制信号,并进行适当响应。 当设备物理连接到计算机系统时,从CPU发送的初始化命令被存储以传送到仿真的外围设备。
