# Radxa Rock 5A Use https://github.com/edk2-porting/edk2-rk3588 (A UEFI implementation) instead of U-Boot Mainline kernel works, as long as it's sufficiently new. I use the SATA hat, which needed an overlay to enable PCIe. Also, the ethernet adapter isn't connected via PCIe, it needs the `dwmac-rk` kernel module (normally it should be loaded automatically, but I need it in initrd).
