Variations in the system hardware are hidden by the BIOS from programs that use BIOS services instead of directly accessing the hardware. <a class="link" href="http://en.wikipedia.org/wiki/MS-DOS" target="_blank" rel="noopener" >MS-DOS</a> (<a class="link" href="http://en.wikipedia.org/wiki/PC_DOS" target="_blank" rel="noopener" >PC DOS</a>), which was the dominant PC operating system from the early 1980s until the mid 1990s, relied on BIOS services for disk, keyboard, and text display functions. MS <a class="link" href="http://en.wikipedia.org/wiki/Windows_NT" target="_blank" rel="noopener" >Windows NT</a>, <a class="link" href="http://en.wikipedia.org/wiki/Linux" target="_blank" rel="noopener" >Linux</a>, and other <a class="link" href="http://en.wikipedia.org/wiki/Protected_mode" target="_blank" rel="noopener" >protected mode</a> operating systems in general ignore the abstraction layer provided by the BIOS and do not use it after loading, instead accessing the hardware components directly.</p> </blockquote> <p>总的来说，就是 DOS 等远古操作系统，在系统跑起来之后，还需要依赖 BIOS，但是 NT，Linux 等现代操作系统，不依赖 BIOS。</p>
