I realized that even setting the bus to 66Mhz, the PentiumII 350 (100x3.5) as well as using the multiplier blocked at 3.5 (obviously) also forces the bus to 100Mhz. It's normal?

On which motherboard?

If it's dual it's kind of cool ... 😎

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

Yes, that's normal. Pin B21 regulates bus speed. If your board doesn't offer jumper or BIOS settings to override it, you will need to mod that pin on the slot connector.
