CPU Pinout?

I have an IBM486 DX4 chip,  
# IBM26 486-4v100GIC.

I think this means it's a 486 DX4/100 operating at 4volts.  Can anyone tell me if it has an intel pinout or not?

That CPU you have is for 3.5 volt.  look at the CPU, you have 4 conners, one of the conner is different from others.  It looks like been cut off a pice.  You pin #1 is right that conner.

But is it an Intel Pinout or something else.  The manual I have for the motherboard desribes jumper settings for IBM chips and IBM chips with an intel pinout.  The board does use a zip socket if that helps

The IBM486DX4 has the same pinout as the Intel 486DX4.  You can find it at:

The comments on the motherboard's literature seems to imply that the IBM chip comes in two pinout configurations.  The page you directed me to details the pinout for the Intel chip but doesn't say anything about the pinout for my particular IBM chip.  You did say that the IBMDX4 chip has the same pinout as the intel chip does that apply to all IBMDX4 models?

Yes, they are the same with the same pinout.  That's why I directed you to the Intel page.  There are two versions from Intel, but I suspect that one you are interested in is the PGA package.  It's the second one in the document.

Thanks for the info.  I was just trying to make sure that I was using the apprporiate jumper settings.
