MPC I checked the command line you posted, if you notice the original of the guide, you will notice that it is exactly the one I posted, if I do copy and paste, obviously I don't go to think that there are more spaces otherwise I would go to intervene. Also while in the line that you had previously pointed out to me, it gave me error of excessive arguments, in this case it takes the command and makes you continue so I could not imagine ... In any case this evening I try in the mode you posted and then I go to redo the command that gives me the error of which I spoke yesterday, let's see if correcting the previous line, I can go on. But at this point it is necessary to report to Meclort because even when you do the NVRAM update in petit boot, the line which is then reported as a guide also has too much space and consequently the system returns an error. Too much space is found after 0 at the end of the line ...
# nvram -p ibm, skiboot --update-config fast-reset = 0
this is the line with the extra space at the end that makes you get out of error, on this I realized and I corrected it, on the others I made a copy paste and I didn't realize it
