   29: # Installation
   30: 
   31: * Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beagleboard.img*
   32: * Build U-Boot for ODROID-C1 <https://github.com/hardkernel/u-boot/tree/odroidc-v2011.03>
   33:   * Pre-built binaries here: <http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/odroidc1/u-boot-odroidc-v2011.03-20150308.tar.gz>
   34: * Note the location and size of the FFS partition in the *beagleboard.img* disklabel:
   35: [[!template  id=programlisting text="""
   36: # $TOOLDIR/bin/nbdisklabel -M evbarm -B le beagleboard.img

   38: 8 partitions:

   51: """]]
   52: * Since the bootloader has overwritten the disklabel, we need to re-add partition "a" from the disklabel to the MBR partition table:

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

   81: * On first boot, it will stop because of the wrong device in /etc/fstab. Take this opportunity to grow the root file-system:
