Just a patch to add the driver to control your raid board to the rest of the kernel (it's not yet a standard driver). The rest of it is easy ;)

I tend to lie the case on it's side (assuming it's a tower) and have all the drives and whatever hanging out, resting on any flat surface I can find, so it's easy to get at. And then only screw things down when I'm confident it's working correctly - I've wasted alot of time doing it the other way around!

I'll be back at my own systems then, so we can walk through building a kernel at the same time, if you wish.

Wow, you actually have that many drivebays? I had to hack my case up to fit my drives in! (6 ide & 1 scsi) I think i'll try putting two pieces of sheet metal down each side of the caddy (slung under the floppy drive etc), going down to the floor, with holes drilled in for drives. That way, I can have drives evenly spaced (with airflow!) from top to bottom. (excuse me thinkign aloud :) There's a photo of the case with just the ide drives in here, if you're bored enough to look:

Yes, AGP is actually addressed through the PCI bus - it's just an extension that allows a differnt addressing from the AGP card to the ram, if I rember correctly. From memory, AGP cards show in /proc/pci as PCI devices, too. It's unlikley, though... fingers crossed :)
I have a whole bunch of cards in with this controller, and no conflicts. It was picky about the *order* though, as this determins who boots first. Also, my network card is picky, causing much confusion!
The thought occurs, you're not trying to boot *from* the raid controller, right? You're saying "boot from the cdrom only" in the bios... so that the raid controller initialises the drives and then is forgotten about.

Did you try booting with *just the raid card and video card* installed?
Do you have access to another system to test the raid card in? (to see if that system boots)

In Linux, that will be /dev/hdc so third, yes. "Secondary Master"

My system I mentioned is a dual p3 with 7 drives and full of PCI cards, and it has no problems running off a 300W psu. I hope :)

None whatsoever. Anyone?

Intresting reason :) Stay away from irc; it's addictive!
