I have a somewhat old system. The mobo can only manage ATA66, but the hdd supports ATA100. If i get a pci ide controller ata100 will the hdd work at ata100?
If you get one with it's own bios , yes.
i have a promise ultratx100. the additional speed was the single biggest improvement i've ever made. i boot from it as c:
i can't remember any probs that came up with it. just follow the directions. good luck:cool:
