Multiprocessor Systems: Dual Celerons

Step 7)

After checking and double checking your work, turn on your system with the first modified Celeron in place. If everything goes ok, your system should boot properly after detecting a Celeron processor. If you don't hear any fans spin up, or the system doesn't boot, immediately unplug the power to the system and re-examine your work. Bad signs to watch out for are no fans spinning, no disks spinning up, and of course, smoke ;)

Step 8)

Repeat steps 1 - 7 for the second processor, being sure to test the second processor by itself, and then with the first processor. If everything worked ok, your motherboard's BIOS should report an Intel Celeron processor running in dual processor configuration. Most BIOS' indicate a multiprocessor system by placing the number "2" after detecting the processor type or something of that sort. If only a single processor is detected, you'll want to double check all of your connections, while being sure to check each card individually before re-attempting the dual processor setup.

Step 9)

If everything finally works out ok (don't worry, you're not expected to get it 100% right on the first try, I had a nice little time getting the second processor card to work properly), cover up your system and start up your favorite multiprocessor operating system. Remember everyone, Windows 9x does not support multiple processors, your second Celeron will go wasted. Be sure to read AnandTech's other multiprocessor articles about the true benefits of and for background information on multiprocessor systems.
