Re: Arduino does not show my Sanguino board

I did everything fine but here is the error message what the arduino compiler said:

Arduino: 1.0.6 (Windows XP), Board: "Sanguino W/ ATmega1284p 16mhz"

In file included from /pins.h:38,
from /Conditionals.h:172,

from BlinkM.cpp:5:
/pins_RAMPS_13.h:15:4: error: #error Oops! Make sure you have 'Arduino Mega' selected from the 'Tools -> Boards' menu.

But I have this board.... What's the problem then? o.O
