Ethernet Card: Atheroes

Wifi/BT Card: Broadcom wifi not working as my wifi model not supported ,Bluetooth not working as i didn't put the kext

On the first boot after the installation, the graphics card was working and sound wasnt. Upon rebooting, the graphics card suddenly stopped working. I have tried multiple efi's but they havent worked. Can anyone supply me with an efi for this? Any help will be appreciated!
