Okies figured out two problems why peeps cannot load windows 2008 server!
#1 no 64 bit math support in the dsdt (acpi) table
#2 the highest windows OS supported in this bios is windows 2000.1 (I think that is the server version (32 bit albeit)
When they made this EFI they totally screwed-up and just pasted and scratched together what they could find, I suspect sparky you'll be able to load windows 2k server on this thing, however you may run into some problems unless you can find and load windows 2000 nvidia sata drivers (if there is an option to set it to ide in the bios you may be successful without having to load drivers otherwise you'll have to find some generic nForce drivers.
Dun even bother trying with raid those drivers are notoriously buggy for win 2k/xp I crashed a recent system based on an ion platform after only a month of usage and gave up and went to darwin on the atom 330 board.
Someone please try to load win 2k server and try ide mode first on sata before angering yourself with f6 and buggy nforce ahci or sata drivers.
this is based on the 10 version of the bios I just started analysing the dsdt.dsl
give updates as I see them workable
