#1 and #3 seem to take forever to actualy hash anything

this is with using 2 5850's and using diablo miner, alnough i have had something similar in cgminer

6  Bitcoin / Mining / BAMT Quick Start Guide For Newbies! on: March 23, 2012, 03:27:42 PM
Bamt Quick Start Guide

This Guide will walk you through getting bamt up and running easily.

This guide assumes the following things
1. You have little if any linux knowledge
2. You want to setup a headless miner (Screen would be nice for first boot if available)
3. Your personal pc runs a version of windows
4. You have a lan network that both your pc and the miner will be connected to

Now that thats out of the way lets get started,

Download the following
1. Win32DiskImager
2. Putty (windows ssh)
3. BAMT (slow download recommend using all mirrors through a download manager)

Ok Now you need a usb drive of atleast 2gb,
All data on this usb will be lost so dont use one with anythign you need to keep still on it.

Open Win32 Disk Imager and select the image file bamt_v0.5c.img
Next select your usb drive letter under the Device dropdown menu
Now click Write
Depending on the speed of your usb this could take upto a hour to complete.

Once the image has been wrote to the drive, plug the usb drive into the rig you want to run bamt on and boot it up,
its a good idea to know what ip the rig is going to use when it connects to your network, so if you dont know hook up a screen to the rig and it will be displayed on the desktop
Ok, now that we have the ip, we need to setup bamt to use the cards for mining and the pool + clock speeds

Open up putty
In the host name box put the ip address of your bamt box
click open,
A box should popup, Click yes
in the black window login as
User: "user"
Pass: "live"

Now we are going to set the root pw
Type "sudo passwd"
and set the pw to something not guessable

And the user pw
"passwd"
And set the pw to something DIFFERENT from the root pw
Now to login as root
type "su" and enter the pw

Now the following command is helpfull if you are running a box headless and for remote management
type in
"apt-get install xrdp"
This will install a remote desktop protocol wrapper on the box, and will allow you to remote desktop in from your personal pc to continue setup and check problems

ok now close the putty window.
Click the start menu and in the search box type "mstsc", hit enter
In the Computer box put the ip of the rig and hit connect
use the same login as above to login.

Configuring your cards
Click the thing down where the start menu normaly is, then configure bamt -> edit /etc/bamt/bamt.conf

Scroll down to "gpu0"
Change "disabled: 1" to "disabled: 0"

Now if you want to overclock the card remember that bamt drives it ALOT harder then the windows miners and you will need to ajust the clock speed acordinaly for this
for example i could have the core at 900 in windows, but in bamt i can only get it to 770 before it goes awol and crashs on every boot

--------------- NOT RECOMMENDED FOR FIRST TIME ---------------
If you do want to set the clock speeds then scroll down to you see
core_speed_0 : ####
etc and plug in your speeds and take of the "# "
--------------------------------------------------------------

I also recommend changing the fan speed from 100 down to 50-70 depending on the heat your card generates when mining

Now save and close this file

Now start menu button -> BAMT config -> edit /etc/bamt/pools
Go down to the end of the file and delete the pool line
Now put in your pool login in the form of
http://user:password@pooladdress:port/
and save and exit

--------------- RECOMMENDED ---------------
Run bamt fixer in the config menu and apply all patchs
-------------------------------------------

Now to see if it works,
Click the start button -> Bamt control -> Restart mining sessions

Open a webbrowser and go to the ip of the box bamt is running on
you should see something similar to this

If you dont see that its accepting shares then post here and il see what i can do to help

NOTE:
You should use the "coldreboot" command from the root username and not just "reboot" or there might be problems

If this guide has helped you attall please send some btc my way (poor college student ;P)
