Yes, I think they talk about it probably not only the revison changed also the chipset. I was thinking to build a Win9x/ME powerful machine with it and I'll go for the 3.2Ghz 512kb not too bad anyway.

Update: it looks like this is one of those boards (reading old articles about the i865PE chipsets) that were theorically able to support Prescott but most mainboards required circuit redesign (maybe on the power to the cpu?). In this link http://biostar-usa.com/app/en-us/mb/introduct … ID=239#download there's the bios that say supporting Prescott for this board, but in the manual it says from rev 1.2 and above so my rev 1.1 would seem to be out. If I will flash the bios anyway may I hope it will work maybe with some heatsinks on the power regulators?
There're four PHB 55N03LTA regulators on this board close to the left side of the socket. Would you think it may work?

UPDATE: I did update the bios of this mainboard to the latest 2006 one that said supporting Prescott but since v1.2 rev. At first I didn't notice that in the official Biostar image sample page, there's probably the newer revision cause mine board lacks two regulators (while there's the empty metal pad for eventually soldering them) close to the cpu. That's probably why in the manual itself it's written than only since v1.2 and above it support Prescott core.
Now, the board works ok (beside some input/output error installing linux on an IDE disk...) with a P4 2.8 Northwood but I noticed that the voltage regulators get really really hot when under stress, almost can't touch the surface more than one second.
Should I try put some heatsinks on them considering I'll put certainly the 3,2ghz Northwood and maybe try some 3.0 or 3.2 Prescott? As said the regulators are this model: four PHB55N03LTA in the SOT404 (D2-PAK) package that seems like capable of 55A of power.

Thank
