Dual Pentium IIIs are still Dual Pentium IIIs. Sure, the chipsets do work. Sometimes. Maybe. If you hold your toungue just right. The problem is not usually reliability so much as compatibility. I can't count how many times I've read README files for Windows drivers that point out some particular quirk that X product or driver has with this or that VIA or SiS or ALi chipset. I rarely ever see those types of "quirks" for Intel chipsets (or AMD's yet, for that matter, even though they only have the 750 and just recently the 760 to speak of). Even some of our (FreeBSD's) own driver writers have kvetched about how VIA or insert-other-lowball-chipset-maker-here has not followed this or that PCI spec or things of that nature. Intel apparently puts quite a bit more compatibility testing into their chipsets, and follows specifications closely (usually). I'm not sure if VIA, SiS, or ALi's inability to create decent chipsets is because of a lack of access to important standards information, lack of engineering ability, or for other reasons (like, they're low-end, low-price chipsets, and you get what you pay for). -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
