ok, heres the deal, i intalled win2k pro 2195 with 1 cpu installed cuz i was too lazy to fix the solder joint on my other cpu(yes i use slot 1 celerons, the REAL way to do SMP with celerons =p), i finally fixed it, plugged it in, bios detects 2 cpus fine, windows wont detect 2 cpus, i even did a reinstall and "repair"
