Do you mean the TX4310?
That was what the shop gave as the Promise internal code. The link they gave, points here: http://www.promise.com/product/product_detail_eng.asp?segment=undefined&product_id=139

But when I scrolled up, the > page says that: "Summary: No TCQ. Newer cards support NCQ. Full SATA > control including hotplug and PM on all." What is confusing? The card supports these, but the driver does not. The comment you quoted about the sata_promise driver suggests that that TCQ will not be supported in the driver, because there is NCQ support in the cards.
I do not know if NCQ and TCQ are related in that way as you say - TCQ is something new to me and my drives do not support that (so, I wont get it even if the software would support it). Anyways, the Promise web-site (above) mentions that the card supports both NCQ and TCQ.
The notes after the table say this: "No, feature is not present. The hardware can support this feature, but driver code does not yet exist to support it." Note the word "yet".
That was the one word that I missed! 8-) Sorry about that. Yes, what I was confused about was, what the hardware supports and what the software supports now or in the future. Now it's clear.
In other words, stay tuned -- the support should be there sometime in the future. If you absolutely /must/ have all these now, then look for something that can use the ahci driver, or get a Silicon Image SiI3124 (presumably, though, most if not all of those will be more expensive than you suggest your budget allows).
I will stay tuned. Obviously I can live without those features (I mean, how did we store our data before NCQ and TCQ? :-) I'll stay with the card that I have selected. After all, I want reliable 4-port solution for home use with my own money... corporate would be different. So, all in all, I'm glad to know that what I selected is now supported by OpenSUSE. And in the future, I might even get better performance. Thanks! -- H -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
