Thanks for the tip, I managed to boot my board as well: http://www.biffuz.it/misc/atom_haiku.png With Haiku, you forget how slow this CPU is under Ubuntu... Only changes required, set SATA to Legacy in the BIOS setup and use Fail Safe video mode. But it's far from perfect: I get random KDLs while reading from the HD. I'll make more tests.
