    - Serial ports with a serial console (hardcoded to 38400 8N1)
 
-Not supported in this version (yet):
-   - LCD driver/touchscreen interface
-   - UDC (a driver exists right now, but is unstable and slow and only
-     works with the Linux USB)
-
 In order to get this kernel onto your Cerf, you need a server that runs
 both BOOTP and TFTP. Detailed instructions should have come with your
 evaluation kit on how to use the bootloader. This series of commands
 will suffice:
 
-   make cerf_config
-   make xconfig
-   make zImage
+   make ARCH=arm CROSS_COMPILE=arm-linux- cerfcube_defconfig
+   make ARCH=arm CROSS_COMPILE=arm-linux- zImage
+   make ARCH=arm CROSS_COMPILE=arm-linux- modules
    cp arch/arm/boot/zImage <TFTP directory>
 
-The default config uses a 4MB RAM disk located at 0xc0500000 as root.
-Setting the board to mount root from a NFS partition works, too.
