I have an ASUS P2B revision 1.10 which came stock with BIOS version 1006. This original BIOS worked fine with a Pentium 2 and slocket Celeron as well as 100 Mhz FSB Pentium 3s but would fail to POST with a 133 Mhz Pentium 3.
Updating the BIOS to the latest 1014 allowed me to use 133 Mhz Katmai processors but not Coppermine; at least not reliably. I have been able to get this board to work intermittently with some Coppermine processors in a slocket but only at higher voltages between 1.9 and 2.0V. I suspect this is due to the board not being designed for these lower voltages. And while the board will sometimes boot with these newer processors, it is very unreliable. From what I understand, the later 1.12 revision works well with Coppermine.
I only have socket 370 Coppermines to test with and no proper slot 1 Coppermines to compare. I tested with various processors at 100, 133, and even a 66 Mhz Coppermine Celeron without stable results.
Can someone with a revision 1.12 motherboard provide photos of the VRMs on their board? I wonder if they can be upgraded or if this requires addition logic elsewhere.
Does anyone have any other information or experience to share on pairing Coppermine Pentium 3s with this board?
