basic input and output system
基本输入输出系统
Computing devices, personal computers, workstations, and servers (hereinafter “computer” or “computers”) typically include a basic input and output system (BIOS) as an interface between computer hardware (e.g., a processor, chipsets, memory, etc.) and an operating system (OS). The BIOS includes firmware and/or software code to initialize and enable low-level hardware services of the computer, such as basic keyboard, video, disk drive, input/output (I/O) port(s), and chipset drivers (e.g., memory controllers) associated with a computer motherboard.
一种基于Linux或Unix内核操作系统的串口映射方法和装置,所述方法包括如下步骤:从基本输入输出系统 (BIOS) 获取第一串口列表;其中,所述第一串口列表存储了面板的至少一个物理串口的串口信息 (S101);从操作系统获取第二串口列表;其中,所述第二串口列表存储了所述操作系统的至少一个逻辑串口的串口信息 (S102);根据所述串口信息对所述第一串口列表的物理串口和第二串口列表中的逻辑串口进行匹配,生成所述第一串口列表与所述第二串口列表的串口映射文件 (S103)。该方法和装置可在不需要人为干涉的情况下自动生成描述物理串口与逻辑串口映射关系的串口映射文件,提高了识别匹配的效率和准确率。
