Trouble disabling One of Three GPU's (cgminer)

[gamechange]

Hey Folks, long time lurker and huge fan of this amazing forum

I have 3x 7970s, one HIS IceQ and 2x gigabyte Windforce models. Because the HIS needs such different setting to get a good hashrate, it needs a totally separate miner with its own config. Up until now I have been using a BAT file with the command  [ -d 1 d 2 ] and it works perfectly to disable card 0.

However, I would love to get CGwatcher working, which requires all the config be done by cgminer.conf

I have been trying for hours to figure out the syntax to disable gpu 0 and enable only gpu 1 and 2, but none work. I saw some advice to place two lines, for example: "device" : "1",
                                                                                                                                                                                                                                             'device" : "2",
but this method only enables one card of the three! Any ideas?



Edit: It is similar to this post: https://bitcointalk.org/index.php?topic=172999. , its getting getting ckolivas' command to work that is the difficulty..

In CGWatcher you can set cgminer options using a config file or arguments or both. As of cgminer 3.1.1, you could not enable more than one device at a time using the config file. Instead you have to use arguments (-d 0 -d 1) if you wanted to enable devices 0 and 1 for example. This is why the "device" option was taken out of the Config File Editor in 1.1.5, because it doesn't work for more than one device so I didn't want to cause confusion by leaving it in. Instead you just have to set these options as arguments.

So in CGWatcher you can edit your profile to either:

a) point to the .bat file instead of the miner's .exe file as the miner path. To do this, change the filter in the bottom right corner of the dialog from Miner executable to Batch or Command file... or something like that.

b) point to the miner's .exe file as the miner path and set -d 0 -d 1 in the profile's arguments. You can still use a config file or arguments for other options, but enabling specific devices has to be done in arguments.
