PCI HDD vs non DMA mobo HDD

[camieabz]

What would give the greater performance?

Current setup:

AMD Athlon 800MHz (100MHz FSB (DDR 200 on the chipset))
PC-100 SDRAM
ATA-66 non-DMA HDD (not sure if it's the drive or the BIOS which prevents DMA here)

If it <b>is</b> the HDD, it's simply a case of a new HDD. If it's the mobo, would the use of a ATA133 PCI controller and a new HDD do the business, or will the HDD still be at the mercies of the lack of DMA?

Which OS do you run? Win2k disables ATA66 DMA at default.

But the onboard HD controller also uses the PCI bus.

But if the HD doesn't support DMA ten a UDMA133 card will be totally useless.

My dual-PSU PC is so powerfull that the neighbourhood dimms when I turn it on

Thinking of getting a controller <b>and</b> a new hard drive. Thing is, I don't dee the point of getting a new un if it's gonna be limited to ATA/66 and no DMA.

Win98SE supports DMA up to ATA133 with the latest chipset drivers.
The preformance difference between an ATA133 device on an ATA66 controller and one on an ATA133 controller wouldn't be that big though.
