Hi, all
I recently got a new Pentium-based machine. It has a nice little horizontal AT case with a Turbo button and a MHz LED. And ever since I've got this machine I've tried my best to get it working.
Initially, it had two triple wires, one labled TURBO_SW and the other one had no lable:
One of them could be easily connected to the motherboard headers, the other one (unlabeled) was too short. So at first I assumed one was for the switch and the other one was for the LED. And so, the only way I could get the LED to work is by either getting a longer AT board with proper headers (which is a bit tricky) or by somehow swapping/extending the wires so they could reach the motherboard.
After getting rid of a small heap of glue I could see where the wires were actually going to. And I finally realised that they are both only connected to the Turbo button:
So, I assume none of these wires actually power the MHz LED, and my system simply came without the wires needed. Here is the back of the MHz LED:
And here are the motherboard headers:
So, how do I get this to work?
1) Which pins of the LED are actual headers that the wires should be attached to?
2) What kind of wires do I need?
3) How do I know at what speed does my CPU run at?
4) How do I get the LED to show the proper frequency for turbo/deturbo state? I assume this is what the jumpers are for.
