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.
