Hello List, After consulting this list I finally build my SuSE AMD64 system (Workstation), and it works really very nice. After the build I performed an install out of the box with linux raid 0 and standard packages, no parameters and all hardware worked without a glitch. All the 64bit and 32bit software I tried worked good. Really a good job SuSE! One detail I have to fix: The machine will not power off after shutdown; it only halts. Then the powerswitch doesn't react either. I have to hold it for 4 seconds to force it to power off. Maybe an APM setting somewhere? Maybe it is not possible with smp instalations? Maybe I'm in the wrong list to ask? Maybe I just have to leave my machine on :-) Does somebody know how I can do this? Thanks.
