The linux kernel is booted with a series of parameters known as the kernel command line. On the BeagleBoard, the uBoot bootloader handles both the booting and the passing of parameters. A typical command line on the BeagleBoard might look something like this:

#console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw rootwait

Modification of the kernel command line is necessary for things like:

ECE497 Static MAC Addresses or

ECE497 Pico Projector

In order to edit the command line, we need to edit a few uBoot files.
