BAMT is a USB-bootable linux distro designed specifically for mining. Litecoin BAMT is a fork of the original BAMT project that supports scrypt mining. Litecoin BAMT has been tested with Litecoin and other scrypt coins like Feathercoin.
More details about the original BAMT project can be found here: https://bitcointalk.org/index.php?topic=65915.0
Litecoin BAMT comes in three flavors (see version matrix here: http://bamt.wikia.com/wiki/Litecoin_BAMT#Versions
Litecoin BAMT 1.4 "7xxx Series (Catalyst 12.8 )" supports 7xxx and older radeon cards, but achieves higher hashrates. I have had reports that this version may work with R9 series cards, I need testers!

EXPERIMENTAL/DEVELOPMENT VERSION (contains bugs, needs testing):
Litecoin BAMT 1.5 "R9 Series (Catalyst 14.1)" supports all radeon cards, including the new R9 series.
Download and extract litecointbamt_r9_1.5.zip from one of these links:
or dd, write "litecoinbamt1.1.img" to a USB stick (2gb or larger).
Insert the USB stick into your mining rig and power it on. To run without a monitor, shut down first then start the machine with the monitor unplugged. Get the IP of your BAMT machine from your routers client list or from the BAMT desktop and connect to it using "Remote Desktop Connection" (or ssh) with the username 'user' and password 'live'.
Once connected to the BAMT desktop, open cgminer.conf (located in /etc/bamt) to edit the cgminer config:
To mine on the BAMT p2pool node, change the "user" to your LTC payment address:
The BAMT p2pool node (http://pool.sgminer.net:9327
) features a low fee of 1% (lower than most competing pools), and income from this pool is invested in BAMT development!
Save your new config, and run "Restart mining sessions" to use the new settings:
The BAMT graphs may show incorrect data sometimes, look at the cgminer console to see the most accurate stats.
Do not use the built in update tool, it doesn't work.
There is a bug in BAMT 1.5 with sgminer and 290x powertune. A workaround that should help is to switch to cgminer: go to /opt/miners, then rename cgminer to sgminer, and rename cgminer3.7.2 to cgminer. Restart mining.
What is a cgminer config?http://www.lurkmore.com/wiki/Cgminer.conf
For getting the best hash rate, tweak your config:http://www.brandonorndorff.com/bitcoin/mining/how-to-setup-and-optimize-your-cgminer-config-file/
For some help with generating a config, try cgEasy
I've included my 620khash 7950 config in cgminer-7950oc.config. Make sure to edit the config the pool entries with your own!
To access the web UI, Navigate to your BAMT IP using a browser:
To see the cgminer console, open a terminal on the server and type:
screen -r xxxx.cgminer
where xxxx is the number listed for the cgminer screen from the screen -ls output.

(1.4.1) (community release by honeybee: https://litecointalk.org/index.php?topic=2924.msg116877#msg116877
- AMD catalyst software Ver.14.1
- Intel´s e1000e network driver
- drivers for the latest radeon series cards
- the latest sgminer (4.0.0)
- support for 6 cards
- modified scripts which support litecoin mining/monitoring
lilyth's pool manager (1.4+):
To enable lilyth's pool manager
, execute the following from a root terminal:
chmod +x /usr/lib/cgi-bin/*.pl
Then navigate to:http://your.miner.ip/cgi-bin/status2.pl?
...to access lilyth's pool manager:
...and config editor:
To enable the config editor, follow the instructions for 'visudo' at: https://github.com/starlilyth/bamt-poolmanager/tree/master/confedit
Note: this feature is experimental. If your plan to expose your miner to the public internet, it's recommended that you execute /opt/bamt-pm/htsec.sh to configure a password for the web interface.
By default, BAMT has remote desktop and ssh enabled with a public password. If you're not using a router/firewall, use the passwd command to change the default password for the "root" and "user" accounts to something other than "live" before connecting to the internet with this distro.
To upgrade to a newer version of BAMT, login with WinSCP file manager and download your cgminer config:http://i.imgur.com/rvIXikm.png
Then install the new release, boot it up, and upload your config with WinSCP.
When upgrading, pay attention to the DRIVERS. For a clean upgrade, use a version with the same drivers as you are currently using. If you plan on upgrading to newer drivers, it is very likely that you will need to tweak your configs.
Do not upgrade to new drivers unless you are having problems, or want problems! It is well documented that older AMD drivers achieve better performance, if the drivers are working for you but you'd like new BAMT features, update manually or request that I post an updated image for your drivers.
- Bad USB stick or write. If BAMT starts to boot, and crashes somewhere, you may have a bad image. Try writing it again, or try a different USB stick.
- Bad USB stick. Really. If your problem is irregular or hard to reproduce 100% of the time, the most likely cause is a crappy USB stick. Try a better one, I use a "Kingston Digital 32GB 100 G3 USB 3.0 DataTraveler".
- Bad config file. If BAMT started fine, and you made config changes and now BAMT does not work, you may have introduced errors in the config. Try to find the problem, or start from the beginning.
- Crashing/Instability. If you are experiencing crashes or freezes, try reducing your overclock, or using a better USB stick!
- Mining stops after unplugging/plugging a monitor. Solution: restart with the monitor plugged/unplugged.
For the best performance, you may need to flash your video card with a BIOS that supports different voltages: http://www.techpowerup.com/vgabios/

Please post your motherboard, graphics card model, hash rate, and settings if you try this distro, I am assembling a list of what works and what doesn't. If you run into any issues, please post in this thread and hopefully someone can help!

Litecoin BAMT is getting popular, if anyone would like to contribute code, documentation, videos, graphics, or anything else, please get in touch! Development & updates are happening in IRC (#litecoin-bamt on freenode).
Mine on the BAMT p2pool node (http://pool.sgminer.net:9327
) to help BAMT development. Simply enter 'http://pool.sgminer.net:9327
' as your pool URL, your LTC payout address as the user, and the password '1', like this:
"url" : "http://pool.sgminer.net:9327
"user" : "LRHxoNPBSVYhQL8u9cvVzdkJo7vvyhBDCE",
"pass" : "1"
