This file describes how you would install Debian's
'Network Installer' or netinstall on an SD Card. This 
SD card would then be used in the Beagleboard to install 
Debian Squeeze.

If you haven't yet downlaoded the git repo which holds the
necessary software, you can do that this way;

$ git clone git://github.com/RobertCNelson/netinstall-omap.git

Then change to the directory you have just cloned;

$ cd netinstall-omap

The following command is an example of what you have to do to
install the correct distro onto the SD card;

./mk_mmc.sh --mmc /dev/sdX --uboot <dev board> --distro <distro> --firmware

You'll need to customize this of course based on your particular needs. 
For example, your SD card might be on a different partition, you can use

$ ls -l /dev/disk/by-path/

to determine where exactly your SD card is located. Under Debian systems it
can often be here;

/dev/sdb

In this case you'd run the mk_mmc.sh shell script with this location
for the --mmc flag, like this;

$ ./mk_mmc.sh --mmc /dev/sdb/

You'll need to also provide the correct argument to the --uboot and the 
--distro arguments. In my case, I did this;

$ sudo ./mk_mmc.sh --mmc /dev/sdb/ --uboot beagle --distro squeeze

You'll need to be root because the script is going to call fdisk which
usually lives under /sbin/

Required Options:
--mmc </dev/sdX>
    Unformated MMC Card

--uboot <dev board>
    beagle_bx - <Ax/Bx Models>
    beagle - <Cx, xM A/B/C>
    panda - <dvi or serial>
    touchbook - <serial only>

--distro <distro>
    Debian:
      squeeze <default>
    Ubuntu
      maverick
      natty

Optional:
--firmware
    Add distro firmware

--serial-mode
    <dvi is default, this overides>

--usb-rootfs
    <root=/dev/sda1>

Debug:
--earlyprintk
    <enables earlyprintk over serial>
