The built in device is probably something like /dev/mmcblk0p1

The line that you probably need to change is root=
I am not sure what you should change it to, though /dev/mmcblk0p1 might
work.  The mmcblk0 refers to the device number, and p1 refers to the
partition.  The numbers may need to change to reflect the specifics of
your environment (well, you probably do not have another SD card, so
likely only the partition number needs to change).

All of this assumes that you can even boot of the integrated card
reader.  It is possible that grub may not be able to boot from this
device.  You may wish to check the BIOS for options related to this as well.
