Short hardware comment:

Your mining computer doesn't need any HDD or CD/DVD/BD as long as it has at
|
||
|
|
least 2GB of RAM, can boot USB, has some network connection to the internet and
|
||
|
|
of course a reasonable mining ATI graphics card
|
||
|
|
... Or you can boot a windows PC with the USB to only do mining ... and ignore
|
||
|
|
the system HDD ... wasting energy Smiley
|
||
|
|
|
||
|
|
To create the USB, you need of course a 4GB USB and temporarily need a PC with a
|
||
|
|
CD (or DVD/BD) writer, a USB port and of course an internet connection to the PC
|
||
|
|
|
||
|
|
1) Download the xubuntu 11.04 desktop live CD iso for amd64
|
||
|
|
( look here for mirrors: http://www.xubuntu.org/getubuntu )
|
||
|
|
|
||
|
|
2) Burn it to CD then boot that temporarily on any PC with a CD/DVD/BD and a USB
|
||
|
|
port (this and the next 2 step won't effect that PC)
|
||
|
|
|
||
|
|
3) Plug in your 4GB USB device and it should appear on the desktop - you can
|
||
|
|
leave it's contents as long as there is at least 2.8GB free
|
||
|
|
|
||
|
|
4) Now run "Startup Disk Creator" in "Applications->System" (the system menu is
|
||
|
|
the little rat in the top left corner)
|
||
|
|
|
||
|
|
(if you have no mouse you can get the menu with <ctr><esc> and navigate the menu
|
||
|
|
with the arrow keys and <return> key)
|
||
|
|
|
||
|
|
From here select the boot CD as the "Source" and the USB as the "Disk to use"
|
||
|
|
lastly move the slider to 2GB for reserved extra space
|
||
|
|
|
||
|
|
The 2GB should be enough for modifications
|
||
|
|
|
||
|
|
Click: "Make Install Disk"
|
||
|
|
After about 10-15 minutes you have a base xubuntu 11.04 boot USB
|
||
|
|
(you can shut down this computer now)
|
||
|
|
|
||
|
|
5) Boot your cgminer PC with this USB stick, select "English"
|
||
|
|
then select "Try Xubuntu without installing" and wait for the desktop to
|
||
|
|
appear
|
||
|
|
(this happens by default if you wait for the timeouts)
|
||
|
|
|
||
|
|
6) Start a terminal
|
||
|
|
"Applications->Accessories->Terminal Emulator"
|
||
|
|
|
||
|
|
7) sudo apt-get install openssh-server screen
|
||
|
|
|
||
|
|
if you have a problem here then it's probably coz the internet isn't
|
||
|
|
available ... sort that out by reading elsewhere about routers etc
|
||
|
|
|
||
|
|
Cool sudo apt-get install fglrx fglrx-amdcccle fglrx-dev
|
||
|
|
sudo sync
|
||
|
|
sudo shutdown -r now
|
||
|
|
|
||
|
|
N.B. always do a "sudo sync" and wait for it to finish every time before
|
||
|
|
shutting down the PC to ensure all data is written to the USB
|
||
|
|
|
||
|
|
9) sudo aticonfig --lsa
|
||
|
|
this lists your ATI cards so you can see them
|
||
|
|
sudo aticonfig --adapter=all --odgt
|
||
|
|
this checks it can access all the cards ...
|
||
|
|
|
||
|
|
10) aticonfig --adapter=all --initial
|
||
|
|
this gets an error - no idea why but the xorg.conf is OK
|
||
|
|
sudo sync
|
||
|
|
sudo shutdown -r now
|
||
|
|
|
||
|
|
11) sudo aticonfig --adapter=all --odgt
|
||
|
|
this checks it can access all the cards ...
|
||
|
|
|
||
|
|
12) get AMD-APP-SDK-v2.4-lnx64.tgz from
|
||
|
|
http://developer.amd.com/sdks/amdappsdk/downloads/pages/default.aspx
|
||
|
|
( http://developer.amd.com/Downloads/AMD-APP-SDK-v2.4-lnx64.tgz )
|
||
|
|
|
||
|
|
sudo su
|
||
|
|
cd /opt
|
||
|
|
(replace /home/ubuntu/ with wherever you put the file: )
|
||
|
|
tar -xvzf /home/ubuntu/AMD-APP-SDK-v2.4-lnx64.tgz
|
||
|
|
|
||
|
|
cd AMD-APP-SDK-v2.4-lnx64/
|
||
|
|
cp -pv lib/x86_64/* /usr/lib/
|
||
|
|
rsync -avl include/CL/ /usr/include/CL/
|
||
|
|
tar -xvzf icd-registration.tgz
|
||
|
|
rsync -avl etc/OpenCL/ /etc/OpenCL/
|
||
|
|
ldconfig
|
||
|
|
sync
|
||
|
|
shutdown -r now
|
||
|
|
|
||
|
|
You now have an OpenCL enabled xubuntu
|
||
|
|
|
||
|
|
13) cgminer:
|
||
|
|
sudo apt-get install curl
|
||
|
|
|
||
|
|
get the binary linux cgminer (see the bitcoin forum cgminer thread for where to
|
||
|
|
get it)
|
||
|
|
|
||
|
|
./cgminer -n
|
||
|
|
this shows you the GPU's it found on your PC
|
||
|
|
|
||
|
|
14) An OC option:
|
||
|
|
sudo apt-get install libwxbase2.8-0 libwxgtk2.8-0
|
||
|
|
|
||
|
|
http://sourceforge.net/projects/amdovdrvctrl/
|
||
|
|
for an Over/underclocking application and get the file listed below then:
|
||
|
|
sudo dpkg -i amdoverdrivectrl_1.2.1_amd64.deb
|
||
|
|
|
||
|
|
15) set the screen saver to ONLY blank ...
|
||
|
|
|
||
|
|
Move the mouse to the bottom of the screen and you see a set of icons like on
|
||
|
|
an Apple PC
|
||
|
|
Click on Settings, then in the Settings window "Screensaver"
|
||
|
|
Set "Mode:" to "Blank Screen Only"
|
||
|
|
|
||
|
|
Edit: originally left this somewhat useful addition out:
|
||
|
|
16) apt-get install ntpd
|
||
|
|
An accurate clock is always a good idea Smiley
|
||
|
|
|
||
|
|
Initial setup complete.
|
||
|
|
|
||
|
|
========
|
||
|
|
|
||
|
|
If you want to SSH into the machine and run cgminer:
|
||
|
|
From a terminal on the miner display each time after you boot:
|
||
|
|
xhost +
|
||
|
|
|
||
|
|
Then after ssh into the machine:
|
||
|
|
export DISPLAY=:0
|
||
|
|
before running cgminer
|
||
|
|
|
||
|
|
Also note, that you should force the screen to blank when mining if the ATI card
|
||
|
|
is displaying the screen (using the screen saver application menu)
|
||
|
|
In my case it takes away 50Mh/s when the screen isn't blanked
|
||
|
|
|
||
|
|
|
||
|
|
This is of course just the basics ... but it should get you a computer up and
|
||
|
|
running and able to run cgminer
