AMD has APPROVED MOTHERboards, approved power supplies, approved heat sinks, etc. - is it wrong for Intel to require Approved graphics cards ?

Dear Bill: The problem is that Intel, contrary to their own created AGP 3.0 (and both the original and version 2.0) specifications, fails to power off the AGP port when a 3.3 only board is inserted. This is just another example of failure to properly work with the previous generations. They conveniently do not tell the public that an AGP port does not allow any AGP card to plug into it. If you look at table 18 in the AGP 3.0 specifications you find what is supposed to work and what doesn't. However, how can a board which is correct to a previous version in force at the time be at fault when the new version comes out? By stating that if an older board is plugged in it should cut power during the power on sequence, if Pin A2 is N/C (open). But how does Intel handle this? It doesn't check the pin, it assumes that a 3.3V board cannot be plugged into an AGP 3.0 socket and doesn't check for a 3.3V board is plugged in. It then wants the AGP board to power off, if the motherboard doesn't support it. Well, too bad Intel! It does not work that way. You just want the problem to go away and it boomeranged right back into your face. Don't you even read what you wrote? The reason the AGP card fails is that at 3.3V true signal levels, the i845 or i850 chipset draws too much current wiping out the chipset (the i845 or i850 cannot take a 3V voltage at any AGP pin). The typical response seems to be a short to ground which may wipe out the AGP card bus drivers effectively killing both MB and AGP card. And all because a user assumes that any AGP card that fits into an AGP socket should work. And even the draft standard says that it should fail, but not break either card or MB. Intel should reimburse all involved, recall all failing chipsets and bring the offending chipsets up to standard. And so what if it takes a big loss. Its the right thing to do. Pete
