CYRIX DX4 CPUS

There are two types of Cyrix DX4 CPUs: Cyrix DX4 with iDX4 pinout

and Cyrix DX4 with M7 pinout.

To determine the Cyrix DX4 CPU pinout, check the CPU label. A
Cyrix DX4 with iDX4 pinout has a “DX4 P/O” indication on the second
row of the lower CPU label. A Cyrix DX4 with M7 pinout does not

have this indication and the lower CPU label has only two rows. See

the figure below.
