you can directly compare P2B 1.10 and 1.12 from manufacturing files (Fabmaster Test Expert) https://www.xwfix.com/?s=asus+p2b you will need https://openboardview.org/ to view the files. *.BOM includes detailed list of all components, sadly 1.10 revision is missing contents of this file.
Main difference seems to be
addition of Chassis Fan header relocated Chassis Fan header to make room for second VPANEL header and VCore jumper - from what I remember this bumped Vcore by 0.1V or something like that. Sadly cant find manual for 1.12.
Interestingly P2B already had VID0-4 configuration jumper block ready! but its unpopulated and disabled by soldered R30A and RN99 (0 ohm jumper links). Removing those two will enable VID jumper block. I clearly remember using masking tape on three VID pins to manually change voltage on my Celeron 300A to 2.2V on P2B. Missing forest for the trees, 24 years later I finally see the VID pins waiting for me to mod them back on the motherboard 😀
1 why would Asus made an effort of implementing full Vcore override jumper block, and then disabling it with 0 ohm resistors?
2 I also realized VID0-4 pins go to HWmon chip WINBOND W83781D https://www.kernel.org/doc/html/v5.9/hwmon/w83781d.html https://pdf1.alldatasheet.com/datasheet-pdf/v … ND/W83781D.html The only thing this chip does with VID signals is report them back, they are wired to dedicated Inputs instead of universal I/O. What a Huge missed opportunity for implementing soft voltage control Bios menu! 🙁 (Btw Asus boardview files have this chip U6 pinout reversed by 180 degrees, oopise).
