Linux Install for EthOS.. Help needed.

I use EthOS and my rigs are mostly with 5.0 or 5.1 PhoenixMiner. I used the Ethos update option. It refers to GitHub for third party miner install script for Ethos. But it updates the PhoenixMiner to 5.3b edition, not the latest 5.4c edition.

I see instructions to download the .exe file for Windows. Can someone point me towards EthOs Install for 5.4c edition without using Ethos miner manager?

Thanks,
