That sounds right; the card has five SATA connectors and its ppb reports "link is x2 @ 5.0GT/s". > If your board has eight SATA ports, No, the card has only five ports, both physically (only five SATA connectors) and digitally (five atabus instances appear in autoconf). > A JMB585 should have no problems to work in a x1 slot. It's supposed to negotiate down to x1? Then either Vantec or ASRock has done something odd or my particular Q1900M has a duff "x16" slot, because it doesn't work. I think my quad wm is a x1 card; if I can find the silly thing I'll try it in the ASRock to see if the slot itself works. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
