It is an on board SATA PCI card. I have 1.25GB RAM. Pentium 4 2.8GHz.
Primary SATA drive (in same card) is 250GB HDD, which works fine and has Vista installed on it.
I did have an IDE DVD-Rom which I used to install Vista (clean) but, once installed, Vista didn't detect that, which is why I upgraded to the Samsung SATA one. Incidentally, when I did have that IDE drive plugged in, Vista took 10 minutes to boot. Since removing it, it takes 30 seconds. However, now if I plug in the SATA drive, it never boots (at least not in under 40 minutes, which is how long I have left it before giving up).
I now have no IDE drives at all.
