Also 1.553 what? 1.553 ohms? K ohms, m ohms?
Without knowing the range of the readings it doesn’t tell anything.
If I make some assumptions about what I think you “meant” it sounds like you may be missing both pull ups and not have a jumper at all for bf1.
But I can’t really make that assumption without clarification on your readings.
You could just order a tweaker and some smd resistors/switch. If your soldering skills are up to it.
You will then have switches for all of this and figuring it out will be easy.
Sorry forgot to mention it's K ohms, that's after I added the 1K resistor though if that makes a difference, and yeah i'm not sure I believe it just measured 0, it's so interesting how this board is set up though, the fact that there is 8 jumper pins to change CPU speed but of course this being a OEM board it's just silkscreened on the board what speed it changes to rather than the multiplier..
Maybe I am missing both pull ups, in that case assuming that what should I do? I might order a tweaker eventually but I wouldn't mind experimenting, I think I remember one post was talking about soldering a wire from BF1 to ground not sure if that applies to my scenario though
