Asus does list the P3 650 to 850 for MEW-AM and RM. Using cpu-upgrade.com it shows as coppermines as supported but only on board revs above 1.00 and certain
Asus probably reworked the later rev boards, and most need a BIOS update .....just an observation.
This is kinda an oddity in a way. I've always seen ASUS use nomenclatures which approximate their compatibility.
P2L slot 1 Pentium 2 440LX, P2B slot 1 Pentium 2 440BX, P3B slot 1 Pentium 3 440BX, ASUS ME?-?? s370 Mendocino, ASUS CU?? s370 Coppermine (with CU being the chemical element Copper which in latin is cuprum), ASUS TU??? s370 Tualatin.
The third letter for s370 boards was often the designation for the chipset used.
MES = Mendocino s370 board with SiS chipset, MEL = Mendocino board s370 440LX, MEZ = Mendocino s370 440ZX, MEB = s370 Mendocino 440BX
This is not 100% foolproof btw, but it does make it easier to see what board you have on hand without having to look up the model number first (or from knowing from top of your head).
MEW = Different, i810 chipset and does support Coppermine CPUs (in some cases!). Usually highly integrated boards, usually not very recommended because i815 and 440BX are usually just plain better. i810 doesn't even have AGP and has some other limitations so it's the odd one out for multiple reasons.
