Hi all,

I thought i would try and get some help in this forum with my problem...that's driving me insane soon! I usually don't have any trouble setting up linux-systems there are usually good guides and common sense mostly get me far but....this one Linux won...and it has to do with something that has to do with how Linux reads PCI-E slots and BIOS settings.

It doesn't matter how i place my two HSI HD6990 cards, only one will be usable in LinuxCoin and with aticonfig and only one will ever get listed in lspci!
I have tried every possible configuration in the slots, and every possible BIOS setting - nothing will make both cards (total of 4 GPUs show in the aticonfig --list-adapters).

Only one card is visible and it shows both GPU's....which is confirmed with the lspci | grep VGA.
As long as only one card is placed in either PCI-E slot 1 or 2 it will work....and if i insert two cards at the same time, still only one card with double gpus will show up and it seems it loads the first PCI-E slot judging by the lspci command.

What annoys me is that there is nothing wrong with the hardware, unless it's totally incompatible with Linux....as it works in Windows 7 x64 every single time. And no, i don't want to use windows :)....im stubborn.

So what can the problem be? I don't think it's a hardware trouble because it works in both slots, and at least 1 card works if i use both slots....and without changing a thin it works in windows 7 x64.

I have for the most part followed this neat guide: http://www.zulius.com/how-to/setup-bitc ... smartcoin/

sudo aticonfig --adapter=all --odgt

Only shows adapter 0 and adapter 1 ...which of course is the only single card it finds from the PCI-E slots.
I have changed every possible setting in BIOS and nothing seem to work.

Sadly the rig is something thrown in my hands to make it work....didn't pick anything myself but heres the mobo and cards:
-Moderkort "Sapphire pc-am3rs890g2"
-Grafik 2xHD6990 från HSI

lspci doesn't show a 2nd card no matter what i do.

What can cause this issue if it works flawlessly in windows without change?

Could it be that i requrie to install the 'real' AMD-linux installation driver to make both slots work?

Thanks in advance and i hope to get some reasonable amount of help :).

Hi,

I think maybe your Hardware is too "new" for this OS? I dont know..

Hmm perhaps,

But these cards are pretty "old" as well ....around that time. But if that's the case, is there an easy way to fix it without re-installing and seting everything up?
I'm pretty sure they're about 2 years old, although i can't confirm it since i didn't do the purchase nor the hw design.

Still not found any simple solutions to this.
Tried with BAMT and some other distros i had laying around, and still same problem so im clueless.
