It is developed by us - Braiins, the company responsible for Slush Pool since 2013.

Um... a bit confused here. The link from slushpool.com (see bottom of page) to it's maintainer Braiinz is to http://www.braiins.cz/.
You're providing an entirely new domain - braiins-os.org - and that too from a newbie account.

How do users trust that you're actually THE Braiinz that's maintaining SlushPool? Maybe a linkback from http://www.braiins.cz/ would help?

Frankly, with the number of scams going around, I would seriously think twice about installing non verified firmware, from a new source, on my antminers. Been bitten once already.

EDIT: The site is genuine. There's a press release on SlushPool as mentioned by @sarcheer a few posts down.

It's awesome! I have 60 L3+/++ and can help with alpha test, if you need, I'm just burning with impatience. It works only with slushpool, or with any?
What's about changes in work S9 on this firmware? You can setting hashrate control, autoreboot and any monitoring services on each piece and stop use awesome miner?

So I went ahead and attempted this OS install.

1st problem: quick guide is not very descriptive! For instance, the requirement to get the control board on the T1 to recognize your SD card requires you to adjust the jumpers on the control board. No guide is given on this besides J1 0 1. I removed the control board from my T1 to get a good look at the jumpers (had to try and find them as no guidance was given on where they were on the board). Upon finding them I had no idea what to do from there or even how to adjust it to make its status 0 1. This is could simply be from my lack of hardware experience.

2nd problem: There is no SD card reader on the T1 control board. From what I can gather from the quick guide, this OS install is predicated upon using the SD card slot. So this is a hard stop and I'm not sure how to proceed.

Can the Braiins team please provide more detailed instructions, like a video perhaps, on the complete, step-by-step process to get the Braiins OS installed on our machines?

Yeah, this isn't going to flash easily on production T1's since those don't have SD card slots.

Thanks Braiins. Any plans on using a different bitstream than the one that is on the S9.

I am able to get an s9 to boot from the SD card but the python script that is supposed to install the OS to the controller itself is completely broken and doesnt work.

It just pukes out garbage when following the instructions to the letter:

So having read through the guide on how to get this os running on the T1, it would seem that some assumptions are made about the experience of the user. If possible, some pictures/more details about jumpers on the board and perhaps some more details on the necessary Linux commands might increase uptake among users.
