- * A10/A20: Download from the linux-sunxi web site
- * A31: The standard u-boot-sunxi tree doesn't support A31 yet. Until sun6i support is merged, a build is available at

-* Write the image to an SD card.
-* Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition.
-* Create or edit uEnv.txt on the MS-DOS partition:

-There doesn't appear to be a meaningful way to generate a MAC address on these boards. U-Boot from the A31 SDK and from the u-boot-sunxi tree both lack GMAC support, and the Security ID registers (at 0x01c23800) appear to be empty.
+# MAC address
-To overcome this, you can specify your own MAC address in *uEnv.txt*:
+On boards where the ethernet MAC address cannot be determmined, a random MAC address will be generated every boot. You can override this behaviour by specifying a MAC address in *uEnv.txt*:
