When you press the power button, press one of the F(number) key usually brings you to the bios. I don't know which one is for your mobo, but here is a guide:

So basically try F1, F2, F10, Del or Esc.

Try the F12 key. That should bring up the Advanced Boot Menu and allow you to chose a USB device.

No, not IDE CD ROM. You have to select boot from USB device.
