Sorry, too much drinkin...
I'm following mstrongbow's post above. I can get to the edit part and enter the code for 275M...copy & paste does not work. I have to enter all commands manually. After I enter the info, I press "I" and it just enters "I" into the file. I can't get out of the edit portion to do the ":wq" command.
The miner boots and runs for a few minutes but starts beeping b/c of all HW(errors I think) and shows no GH/s.
Tried again and seems to be working now. Putty is a PITA to navigate through. I watched the video but the guy was on a mac and it was different.
