This is what Intel planned originally. However they failed to account
for the Independant Motherboard Manufacturer. These days a lot of the 
motherboards will take a 486SX or DX interchangeably, with a simple 
jumper setting, in the same socket. They often also have the extra 
socket for the overdive chip (modified 486 DX2 or the mysterious chip-
to-come).
