Empty socket beside Intel486 processor—go to Step 5.
Empty Weitek socket beside Intel486 processor—go to Step 4.
486
Pentium OverDrive processor socket with Intel487 SX math
coprocessor installed—go to Step 4. (Intel486 SX processor
systems only)
Surface-mounted processor only—not compatible!
Possible System Layouts

If your processor is soldered to the motherboard in a surface
mount, and you do not have a separate 237 or 238 pinhole
Pentium OverDrive socket, you cannot install the Pentium
OverDrive processor. Do not attempt to remove the
original processor!
If the empty socket does not contain 237
or 238 pinholes (19 pinholes per side),
you cannot install the Pentium OverDrive
