![dnsmasq proxyDHCP PXE 和 EFI“start_image() 返回无效参数”](https://linux22.com/image/720413/dnsmasq%20proxyDHCP%20PXE%20%E5%92%8C%20EFI%E2%80%9Cstart_image()%20%E8%BF%94%E5%9B%9E%E6%97%A0%E6%95%88%E5%8F%82%E6%95%B0%E2%80%9D.png)
我正在尝试使用 dnsmasq 在 proyxDHCP 模式下安装 PXE 安装服务器。到目前为止,旧版 BIOS 安装正在运行。当我尝试使用 EFI 时,它会失败。
使用 dhcpd,EFI 启动可以正常工作。因此垫片文件应该没问题。

答案1
我遇到了同样的问题,花了一段时间进行故障排除。shim 和 grub2 的工作方式很奇怪。您必须将主 DHCP 的“next-server”设置为您的代理 DHCP 服务器。iPXE 和 BIOS 启动不会在意您是否有未设置 next-server 的代理 dhcp 服务器,如果没有它,grub 和 shims 似乎会失败。
