→Booting the XO from the SD

====Booting the XO from the SD====
More than likely, this will not work right away, my implementation required some tweaking prior to fully booting.

*With the SD card inserted in the XO, turn the machine on and press the "Esc" key to interrupt start-up.
*At the prompt type:
<pre>
ok boot sd:\boot\olpc.fth
</pre>
*It should attempt the boot sequence, but more than likely will fail with a Kernel Panic!!!....error
*This is almost expected, but it's actually an important step. If you look further up on the screen, you should see an error in regards to mounting the file system.
*Around this area, you should also see a list of strange numbers (i.e. b102:) followed by devices (i.e. ramdisk...)
*Find the row for your SD card, it should be labeled something like:
<pre>
b301: mmcblk0p1
</pre>
*Remember the b301 number.
*Connect the SD card back to the Linux PC.
*Open the file /boot/olpc.fth
*You'll see a line like this:
<pre>
" ro root=mmcblk0p1 rootdelay=1 console=ttyS0,115200 console=tty0
rootfstype=ext2 fbcon=font:SUN12x22" to boot-file
</pre>
*Change the "root=******" to be the variable recorded earlier.
