Hi Gerald,
I have the A3, and many others are reporting problems booting
Ubuntu maverick, I found that the DVI is not being enabled. although
the LEDs blinking is supposed to be indicative with the User screen
waiting for input. I know the angstrom minimal that shipped with my
board works, which specific pin was the DVI PU moved too so we can re
compile the ubuntu release and correct this?
