(probably not in the right section so sry for the trouble if it is) Ok I now have an extra 550mhz computer with no hdd and I was wondering if there is anyway to network it with my main opteron rig so I can use it as a computational node. Not sure if this is completely possible without the node having its own hdd but I thought I would ask here anyhow. Thanks in advance. The other thing is I want to still be able to use XP pro on my main rig as the main OS while using the extra node. I am not sure if this is possible to do this short of making my main rig running dual boot and using linux.
