soekris net6501，PXE，领班和启动顺序

我正在尝试通过 foreman 将 Ubuntu 16.04 配置到 soekris net6501。该过程本身现在实际上运行得相当顺利。

有一件事没有做我们想做的事是后配置。这个想法是能够在任何阶段将新映像/操作系统部署到盒子中，并让其默认尝试 PXE 启动，如果 PXE 未发生，则转到本地磁盘。

因此，当 foreman 设置为构建主机时，PXE 启动工作正常（经过一些调整和实验），但在配置完成后第一次重新启动时，机器就会挂起。

PXE-M0F: Exiting Intel Boot Agent.

如果我更改 BIOS 以选择本地磁盘，那么一切都会好起来。但这不是我想要的；有些机器会放在数据中心，带着笔记本电脑在那里摆弄串行控制台是不可取的。

然后它就呆在那儿。

通过反复试验，我了解到该LOCALBOOT 0命令并不适用于所有硬件。

您需要为不同的硬件设置不同的磁盘启动命令。在 syslinux wiki 上了解有关硬件兼容性问题的更多信息：http://www.syslinux.org/wiki/index.php?title=Hardware_Compatibility#LOCALBOOT

以下是我们使用的 3 种不同的“硬盘”启动命令，没有一个命令适用于所有硬件。

KERNEL chain.c32
APPEND hd0

LOCALBOOT 0

LOCALBOOT -1

另外，我还发现并非所有 syslinux 版本都能同样好用。因此，请尝试不同的版本，看看哪个最适合您的硬件。
