Partition layout

The x86 image is using the following partition layout (as seen from inside of the device):

/dev/sda1 is a 16MB ext4 /boot partition where GRUB and the kernel are stored.
/dev/sda2 is a 256MB partition containing the squashfs root filesystem and a read-write f2fs filesystem OR the ext4 root filesystem (depending on what image you have chosen).

Any additional space in the device is unallocated.

Install

Download from https://downloads.openwrt.org/releases/23.05.4/targets/x86/64/
squashf和ext4镜像的差别：squashf文件系统可以实现一键重置功能，但是无法拓展用户空间； ext4文件系统能扩展用户空间，但无法实现一键重置功能。这两种镜像根据具体使用条件选择烧录哪一种。
