I have the intel D850mv motherboard with socket 478 chipset. it has no sata ports, only ide. Would I be able to add a sata port pci card and then boot off that as my main hard drive? I want to do this instead of getting an ide hard drive because i some day hope to upgrade the mobo and processor and would like to not be concerned about finding one with a ide port for my disk drive or hard drive and wont want to buy a new disk drive or hard drive if they both are still operational. Should the sata drive connected to my pc via pci be able to be my main hard drive (boot device)?
In short.... the answer is no in you case. The board that you have does not support the boot to pci that you will need to use the drive as a primary boot drive. Sorry to be the bearer of the news.... :-(
