Hi, I am trying to unbrick a optiplex 3010 for a customer and I made a interesting discovery while trying to dump the bios from a working unit. If you change the me_clr jumper from the normal 2_3 position, to 1_2 and boot the system up, you get a "warning service mode enabled press f1" and then you can continue to bootup. With this set, I was able to use flashrom to read out the entire flash chip (this may or may not be 100% true but will still help me) I am attaching 2 files that show the difference between the 2 jumper settings. After this weekend crisis with this customer pc, I am willing to try this jumper trick on other optiplexes I have if you wish, 360, 755? I think You guys helped me get a little further on this rescue and I appreciate the help and info over the yrs Sincerely Jason J Salopek aka "flyback" --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
