I'm the one who originally posted the question, and now I may have an answer (with help from the list): > I've tried doing that, 2.2.14 adding both patchs. > mostly they failed everywhere. then once I did it get it in, and compile, > it still never worked right, I change to 2.3 kernel, even tho alpha/beta > kernels are buggy, alteast it's working for now.

I'm doing it right now. Download the plain-vanilla 2.2.14 kernel. Apply this patch first: http://www.kernel.org/pub/linux/kernel/people/hedrick/old/ide.2.2.14.20000124.patch.gz Then apply the RAID patch that <[EMAIL PROTECTED]> posted here earlier, called raid-2.2.14-B1 (I don't have a URL but I can mail you what was posted). Then configure your kernel properly (email me if you have questions), compile it, install it, and it does miraculously work. Mine detects the RAID partition on boot, and mounts it on boot, without having to modify init scripts at all. I'm very impressed. I promise you that 2.2.14 + Promise Ultra/66 + RAID works (in that order)! The Promise Ultra/66 card has been a total nightmare, but now that it's working, it's the way to build big fast RAID arrays as cheaply as possible. I think it's about half the cost of doing a comparable solution with SCSI. This savings will be worth it if you're building a cluster of these machines. It's just unfortunate that Promise isn't aggressively supporting Linux, and didn't get an Ultra/66 driver into the RedHat 6.2 release. e -- This message was my two cents worth.
