|An IDE port will accomodate 2 IDE devices so unless you plan on using more than 2 you can just use the motherboard port.|
But the card I was talking about was one of these:
That seller is selling 4 of them in different lots. Edit 2 are ata100 and 2 are ata133. You'll probably want the ata133.
They have 2 IDE ports so they can accomodate up to 4 IDE drives. They are 48-bit LBA compatible for IDE drives larger than 128 gig. Most of these older cards have problems if you connect a cdrom/DVD drive to them. So optical drives should be connected to the motherboard's IDE port.
I assume the card is compatible with windows 7 but have never tried it.
