Someone on twitter has a Biostar MB-8433UUD-A Rev 2 that is missing the RN11/12//13/14/15 resistor networks/packs needed for selecting CPU type. Does anyone know the value / part number of these?

I found a few threads on here suggesting that some of you have this motherboard, so I thought I'd ask.

Mystery solved? https://twitter.com/DosFox1/status/1223659709988851713

It seems they may actually be B000J jumper packs.

Thoughts on how to go about fixing this?

I have a different 486 board that has those "resistor" packs. Will try to get it out and take some measurements this weekend.

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....

Ok my only board with them is a Giga GA486IM rev.2. The "resistor" packs are labeled SMT BOOO G and are O ohm between pin sets. Just like the BOOO J in the links above. See pics below

This is the best picture I could find of the Biostar MB-8433UUD socket area, and it appears to have BOOO J written on them.
Big Thanks for asking about this as I have wondered if those were really resistors (like SCSI Term resistors) but never looked into it.
