摘要： A keyboard controller which scans entered input sequences for an input sequence to activate a display blanking feature. A password and particular hot key are loaded by the system microprocessor. The keyboard controller then scans until the designated sequence is activated. The display on the monitor is blanked until a password sequence is entered. The password mode may be directly activated on command from the system microprocessor. The display blanking feature is especially useful in conjunction with a keyboard password lock.

摘要： A computer system provides emulation routines that cause a keyboard or mouse to appear to be present to the system software even when the devices are not physically installed. On system start up, this allows installation of appropriate device drivers by the operating system. If a keyboard or mouse is later installed, the emulation responses are discontinued, and a keyboard and mouse operate normally. When the system is placed in a standby state, the keyboard and mouse connectors are totally powered down. Before this power down, the BIOS routines save the configuration state of the keyboard and mouse as recorded by the emulation routines, which have been tracking commands sent to those devices even when those devices are operating. When power is re-enabled to the keyboard and mouse connectors, the configuration of those devices is restored from that saved configuration data. Further, the system detects whether a keyboard or mouse is installed on a particular connector and appropriately maps the keyboard and auxiliary ports to correspond to that connector.

摘要翻译： 计算机系统提供仿真例程，即使在没有物理安装设备的情况下，也会使键盘或鼠标似乎出现在系统软件中。 在系统启动时，可以通过操作系统安装适当的设备驱动程序。 如果稍后安装了键盘或鼠标，则会停止仿真响应，键盘和鼠标正常运行。 当系统处于待机状态时，键盘和鼠标连接器完全掉电。 在此电源关闭之前，BIOS程序保存由仿真程序记录的键盘和鼠标的配置状态，即使在这些设备正在运行时，这些仿真程序也已经发送到这些设备的跟踪命令。 当电源重新启用键盘和鼠标连接器时，这些设备的配置将从保存的配置数据中恢复。 此外，系统检测键盘或鼠标是否安装在特定的连接器上，并且将键盘和辅助端口适当地映射到与该连接器对应的位置。
