[SATLUG] 4 port PCI SATA controller

[Jeremy Mann]

John, the 64bit PCI card will plug into a standard 32bit slot but the
64bit section of the card will just *hang* off the PCI slot, unused.
I've done this many times with problematic NICs. The only problem I've
come across is in older motherboards. Its kind of hard to explain
but......

The white plastic end of the PCI slot towards the back is sometimes
not wide enough for a 64bit card to fit. You can force it all you
want, it won't slide into the 32bit slot. In later models of mobos,
I've seen the manufacturer cut an indention that will let you plug in
a 64bit card.
