Only one core shown!!!

I used to frequently do this with my PIII system under windows 2000, as i was playing with the effect it had on the timing of a device driver i was developing. Had no side issues what so ever, its fun not having to compile a new kernel.

indeed not, which is why most distros have shipped SMP-only kernels for a while

thank you all who posted, with your guidance i was able to get both cores working by means of using the installation disk for vista, without removing all my files as mentioned by directhex, so again thank you for your helpful advice.

In Windows? Without breaking a bajillion other things? Do tell

using xp when i upgraded from a fx-53 to an opty 165 all i did was change processors make changes in my bios then boot up. windows said it had installed new hardware and needed to reboot. once done xp saw both cores and both were displayed in task manager. is this unusual i thought this was usual until i saw this thread.

the obvious way. right click on the HAL in device manager, update driver, pick frmo the list

Interesting... I tried this twice in the past and ended up with various bluescreens. Just tried it again and it seems to be working ok (though in all honesty I've not tested too much)
