Appending nomodeset will disable the Intel Xorg driver. This may be OK for testing, but is not an option for normal usage. The better option would be to set the resolution and refreshrate of the monitor manually using the
video= option (the vga= option is deprecated and useless for modern Linux video drivers), for example:
to set up a resolution of 1024x768 pixel with a refreshrate of 60Hz.
Having said that, the Atom D2500 CPU on that mainboard features the PowerVR SGS545 video unit (relabeled by Intel to fit their HD naming scheme), which under Linux only has some 2D acceleration and almost no 3D acceleration functions. This doesn't matter for a server, but if you want to use this mainboard in a desktop system you are much better off with using Windows.
