Hello,

I have a Promise Ultra66 card that I am using as a IDE controller (not using RAID features)  I have had no luck installing Mandrake, OpenBSD, or FreeBSD.  My latest project was FreeBSD but it doesn't seem to be supported.  I have read posts saying "sure it works fine" but I don't see any drivers.  Any plans to get this working?

The problem, as I understand it, is that the Promise cards aren't true raid controllers and the driver is responsible for the bulk of the RAID functionality, i.e., it's sort of a "winRAID". My suggestion would be to dump the card on some poor benighted soul that only runs windows and get a 3Ware IDE RAID controller. They work "out of the box" with RedHat and FreeBSD (and probably others... I've used it with those). Take a look at their products at http://www.3ware.com/

The promise Ultra66 card is not a raid card of any sort.  It is simply a IDE controller card.  I assume that the card works at post time?  It should list the devices attached to it after the machines bios finishes it's post.  These cards don't work "out of the box" with FreeBSD versions 4.0-release and earlier or RedHat versions earlier than 7.2.  You could build the driver for them in the earlier OS's after install though.  The cards do work fine in all newer versions of FreeBSD, NetBSD, Mandrake, SUSE, and RedHat I know from experience as long as there is not an IRQ conflict with another device in the machine.
Hope that helps
