Yeah, the chipsets also are all handled by their own code, MVP3 setup isn't the same procedure as PIIX4 setup or ALI1541 setup.... I know, from my experience that my specific revision of the 586B works fine. Some of it I have noticed is also from cramming three or four drives onto the mobo controllers. I have had DMA33 troubles with two hard drives sharing the same channel, stuff like that. Some of that is chipset specific, but if you really need that many devices you should really look into SCSI, I have one CDROM on my secondary and a hard drive on my primary and it works well. If I wanted to add another hard drive or something, I'd probably save up for a SCSI controller and a SCSI hard drive. You start slaving devices on the IDE bus and it really degrades performance, especially mixing UDMA and non-UDMA drives. Most manuals for them specifically say not to do that. --cokane Warner Losh had the audacity to say: > > In message <20000405150146.B6856@evil.2y.net> Coleman Kane writes: > : The original point was that the troubles weren't necessarily > : chipset-specific or mobo specific.
