Why on earth do you want a software raid? I thought you have a hardware raid controller?

It shouldnt sit there showing a cursor with no prompt... it should exit the raid's bios and continue booting the system.

Yes, dont use software raid! Ok, so ata raid controllers are not the most effecient (they do still use the cpu, as opposed to "real" raid controllers, which handle everything in hardware), but you do still want to have your raid controller do the controlling if you want any appearance of speed.

Remove the raid card from your system (unplug it from the motherboard) and see if you can get the system to boot without it. We can install raid later - one thing at a time!

Do you plan to install your OS to the raid disks or to another disk on the motherboard's ide controller?

It's a Silicon Image 0680 controller, with a Silicon Image Medley bios (not to be confused with your motherboard's AMI (american megatrends incooperated iirc) bios.) I happen to have the same controller in my desktop machine.

great. I'll leave you in Jenn's capable hands for getting the system to boot. Again, remove the raid card until you're sure everything else is ok - right now, it's only confusing things.

I'm sorry, i dont quite understand what you trying to say here. If you mean is there a jumper on the pci card, all I rember is a couple of headers to connect LEDs to indicate disk activity.

No, that wont effect anything

quite :) wait until you get to the kernel configuration ;)
