FYI below is my experience regarding intel's DC2500CC (dual NIC board)
initially tried pfsense 2.01 64 bit - no matter what i do, it does not install (more details later). then tried 32 bit, after some minor tweaks, finally had it installed.
initially tried to use USB DVD drive, it ran into several problems, then tried an internal DVD drive, it passes problems but still suffers a graphic issue - the screen does not refresh, only the very last line of text is over writting part of last line (not sure how to describe this). tried safe mode and other modes, no luck and cannot really see what it is doing because of the graphic/text issue.
i could have tried with an PCI-E graphic card i guess, but instead decided to give 32 bit a try.
screen refreshes ok. however once at the blue screen where to set the installation options, graphic / text becomes strange again. by remembering first option at the installation options is to change video setting, i changed a few diff fonts and one seens to at least allow me to see half of the text. eventually had 32 bit installed.
i guess the above means there is some compatibility issue with the new atom's built-in graphic? BTW i've also had installation on intel's D525MW, bith 32 and 64 version installed perfectly.
am i the only one seeing this problem? anyway i am going to stick with 32 bit for now until / if there is a solution to it.
