i made a thread earlier about which mining rig to buy.
i have bought ati 6990 and a good motherboard etc...
installed ubuntu on it and followed this guide: http://forum.bitcoin.org/?topic=7514.0
now this is fixed... i followed the guide and everything went good.. but i couldn't see my gpu in terminal. so i did research and found out sdk 2.1 dont support 6990.
im trying to install sdk 2.4, but in terminal it dont work and manual i dont get permission.
second, i have no idea how to start mining with my 6990 and what other steps i have to take other then what the guide explains.
any help is very appreciated.
