help on starting up ubuntu

Its quite possible that there is another thread like this but i can
find it. i was following the directions on how to build and boot up
ubuntu on the beagle board. ive goten everything to work so far but i
have come to a spot where i have to make a U-Boot boot image and that
looks like i have to edit it when the board boots up. but underneath
that it says to create a boot source. where do i find the ubuntu.cmd?
is that still when the board is booting up? or is that something that
im missing on my development computer?


Ah, you must be here:

ubuntu.cmd is a new file that your create with the text shown:

setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=ttyS2,115200n8 console=tty0
root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro vram=12M


Thank you would this then be put into a terminal on the host computer then i take it.
