Pentium IV Non-bus Master PCI Bug Lives

Barbarian writes "This ZDNN article says that a bug in the Pentium IV chipset that caused a recall months ago and causes a slowdown on systems with a second (PCI) video card still exists. A talkback comment points out that this bug affects any non-bus master PCI device." To be fair, the probable amount of people that it will effect is relatively small, and even if you do want two monitors, most companies are just using the Matrox G450, or one on the AGP, one on the PCI.

Just a reminder for the Pentium complainers

It is the CHIPSET with the bug. Not the Pentium IV chip itself.

The problem is...

The problem is, if my understanding of "Video and graphical data" that they are referring to, this is more than just dual monitor systems. This also means that the whole raft of high-end video editing systems are going to have problems. And perhaps DVD decoder cards, too.

I suspect that the major issue here is that Intel doesn't want to do a recall on the boards that have already been made, like the i820. So they are figuring that this isn't a major enough problem, so they are going to just let it ship.

It doesn't bother me because I'm not going to buy a P4 of this vintage. If I upgrade, it'll either be to a fast P3, the next version of the P4 and chipset, or an Athlon.
