Comment by Paul Collins (pi314aussie[at]
When this chip came out, I had a "huge" form-factor (full-AT-size) 486 M/Board. It had sixteen SIMM sockets, but had no clock-crystal socket. This was before end-user jumpers for clock generators were around, thus I was locked into 33MHz, due to the crystal being soldered. I tested a DX2-66 CPU in this giant M/Board, but the (very very) early BIOS didn't let it work. If I wanted to use a 66MHz chip, then I needed a new M/Board that supported such things. By then, the newer M/Boards also had settings for DX4's as well.
The DX4-100 soon followed into the market. As a result, I bypassed the i486DX2-66 altogether, and bought the latest and greatest i486DX4-100. So, I never experienced to joy of owning a -66.
