More than likely, this will not work right away, my implementation required some tweaking prior to fully booting. | 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. | |||
