Putting a 486dx in an Intel overdrive slot

[Arbystpossum]

The Idea is simple enough, I have a board with an on-board 486SX-25 and I want to make it a DX2-66. It has an older blue Overdrive Ready socket as well, I tried dropping a DX2 cpu in the socket and the system won't boot. I read that the on board cpu may need to be disabled, which there is no jumper for. Does there exist a riser or spacer or something that grounds the appropriate pin so I can use a regular socket 1(i think) cpu instead of specifically an Overdrive cpu? Picture is of the socket in question.

The motherboard likely needs to have jumper settings changed for a DX2-66 processor to work. If you post a photo of the whole motherboard, we might be able to help figure out which one it is. And if a site like The Retro Web has the motherboard listed, we might even be able to help with which jumper(s) need to be changed.
