I removed a UM8663BF Super I/O IC from a revision 3.1 Biostar MB-8433UUD motherboard. The silkscreen shows UM8663AF/BF, so perhaps you can use either of these. This particular MB had a defective floppy controller, so I am hoping the replacement fixes the issue.

Hello feipoa, I just acquired a revision 3.1 Biostar MB-8433UUD motherboard recently but cannot find any documentation online explaining what if anything makes this board different from a rev 2.
Are the BIOS updates compatible between revisions, and do they support the same CPU models ?
