Hi, I'd like to announce that as of r48278, you can build a full x64 bootcd (including rostests, not rosapps) from trunk. That means from now on, I can quickly see when someone breaks 64 bit compatibility: http://reactos.ath.cx:8081/waterfall So please don't cast PVOID to ULONG ;-) Regards, Timo PS: no, it doesn't boot to desktop
