请教下这台机器是旧世界吗？是不是因为旧世界的原因导致安装ArchLinux-loong64引导不了？

fqucuo 进bios看下，拍个图片发下看看

小胖

还是有些困惑，新旧世界指的是主板固件，还是指的是CPU呀？

fqucuo 固件

fqucuo 你这个是旧固件 装archlinux需要刷bios升级

fqucuo 新旧世界指的是主板固件，还是指的是CPU呀？

固件有新旧两种接口，操作系统有新旧两个生态。

https://github.com/loongson/Firmware 或者 https://gitee.com/loongson/Firmware 自取 A2101 的固件刷（做好备份，别怪没提醒你）然后 Loongnix 和 Arch 等系统就都能用了
