As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days).
Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present.
Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my friends for a few hours/days and use it when installing the necessary software.
Can I boot and run the PC without problems after I install everything I need and the graphics card is removed? If a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpful.
I think it's obvious, but for completeness, I mean cheap desktop components and not real servers.
Does a modern PC require a graphics card to run?
I believe that many motherboards can boot without a video system. (but I have no actual experience of this)
Wikipedia says
During bootup, some (especially older) PC BIOS versions will wait indefinitely for a user to press a key before proceeding if some basic devices are not installed or connected, effectively halting an unattended system. These can include:
- a video card;
- a keyboard.
在更现代的系统上，BIOS工厂设置通常也将配置为以这种方式运行，但是可以通过BIOS设置工具更改此设置，以在无需用户干预的情况下继续进行操作。即使在将系统设置为可以远程管理的情况下，仍然可能会不时需要使用本地键盘和视频卡，例如，以诊断在初始化远程访问应用程序之前发生的启动问题。
当然，许多服务器级主板都是为此专门设计的-Wikipedia文章提到了这一点，我有HP和IBM服务器，其中包括对启动消息等的某种基于以太网的“控制台”支持。
通常，我会下载并阅读主板手册，并检查是否有一个选项可以使启动继续进行，而不会在出现错误后按任何键
例如在ASUS UEFI BIOS上
等待'F1'如果错误[启用]
当设置为[启用]时，系统会在发生错误时等待按下键。
