我正在尝试在裸机 Micor 服务器（Intel Rangley/Mohon Peak 平台）中安装 Ubuntu 服务器操作系统 (ubuntu-18.04-live-server-amd64.iso)。我的服务器没有板载或板外 VGA 卡。我使用串行控制台进行显示。我尝试过通过串行端口安装 Ubuntu 操作系统的不同方法，但我能够获得视频直到 grub，之后我就看不到视频了。通过更改 grub.cfg 值，我仍然无法获得显示。
您能否提供通过串行端口安装服务器操作系统的步骤？
我已经分享了我的 grub.cfg。请查看。

我尝试过用各种值更改 grub.cfg，但仍然没有显示。我收到以下错误。
