On the back of the DE2700, the upper right USB port is where you should plug in your keyboard; hitting del on startup will get you into the DE2700’s BIOS. I don’t know why the other USB ports don’t respond the same way to a keyboard, but they don’t.
On the back of the DE2700, eth0 is the left ethernet jack, and eth1 is the right ethernet jack.
to get a boot menu, hit F11 when booting up
