HMI with pc

Hi, this might be little other thing than plc problem but I will ask it here. I got very small pc (eBox552) and I cannot install Win2000 os in it. Installation stops with bios incompatible note. Have somebody information how to get and there right bios to the pc. Pc works fine with XP and also win98 but not with Win2000.

So what's wrong with XP? Can't you leave it?
Most systems should work with Win2000 if you enter BIOS
and change PnP setting for OS.
