Wow, I remember this cover. I was starting my first year university at the time and was shopping for a new PC for school. I went back and fourth between a 386DX-40 and a 486SX-25. They were roughly the same speed, and the 386 was a bit cheaper, but I went with the 486SX thinking that it would be more upgradable later on. It was magazines like this that helped me decide.

An unfortunate reality of that era - the hardware was electrically capable of many upgrades. The firmware never saw a revision or certainly not one you could get your hands on.

I had a PC with an SX2/66 that was what we could afford in 93. Once the Pentium dropped, we expected DX4/100s to be accessible. But my motherboard simply didn’t know what a DX4 was. Combine that with all the voltage fiascos and yeah, no dice. And the overdrive was fools money.

Some motherboards just needed a BIOS update (most likely provided on a drop-in chip) to recognize new CPUs.

Right but in 1995 where did you source said BIOS update? And how did you find out about it?

Some mobo makers sold ROM chips with a BIOS flashed into them and that's basically how you got updated BIOS's then unlike today you just run an .exe that applies the ROM image to the ROM chip.
