Isn't the Pentium's microcode upgradable? Or is that only in later chips?

These fixed transistors imply no upgradability.

Microcode updates were first implemented in the Pentium Pro. When the original Pentium had the infamous FDIV bug, the only fix was for Intel to replace the processors at a cost of $475 million.

Good thing win95 came out soon after and filled everyone’s coffers from new equipment buying
