@azonenberg The f00f bug is probably in microcode, so here's a random piece of the Pentium's microcode as it appears on the die :-)

A closeup of the Pentium die showing part of the microcode. The image shows horizontal lines with a scattering of squares. The squares are transistors, which result in a 1 bit in that location.
