Have not had a chance to check yet, but does the new version for the mini have support for the fourth board and will it support voltage control (Please disregard the PM I sent I think I figured that out) If not I can do the mod and check the z11 firmware on the mini. The z9 big will not arrive until tomorrow for me to see what needs to be done on it if anything.
Thanks,
Keith
If you have WinSCP you can edit the minerStatus.html in the /www/pages/cgi-bin folder and then you can see the 4th card. The edit is temporary until a reboot then you will have to do it again if I remember correct. The code to paste into the page is below. You will see that is is coded 4 a 4th board.
