+==== Deploy (boot from Compact Flash) ====
+  * Partition 4GB Compact Flash card
+Let's try to boot Linux directly from WinCE using [[http://xdandroid.com/wiki/HaRET|HaRET]] bootloader. In order to do that, create two fdisk partitions on CF card. The first one with FAT filesystem containing HaRET bootloader along with its configuration file and Linux kernel. The second one is formatted as ext2 and will contain Linux root filesystem.

+heads, 62 sectors/track, 1023 cylinders, total 7806960 sectors

+Sector size (logical/physical): 512 bytes / 512 bytes
