Yup, it was jumpered for a DX4-100. It was missing the jumper to say whether the CMOS should run normally or clear and it's jumpered for 256 KB cache with no cache installed, however there is no jumper for "no cache" so I guess that leaves me with a problem, unless I can find some chips I can salvage off an old motherboard or something.
Edit: Well, nope, it was jumpered for an SX-33, this is just one ****ed up board when it comes to jumpering, and for some reason the BIOS reported the CPU was running at 50 MHz when it was actually jumpered for 33 MHz...
Well, lets go test to see if it reports the DX-33 correctly since that is what I just added and re-jumpered for.
