Stefan,
Thank you for the help (IRC) this past Sunday with flashrom and my Z820. You had to drop off the channel before I sent message that the Z820 had not bricked. It rebooted and all is fine.
I posted the flashrom -o file hoping some bright minds (brighter than mine) have some suggestions. I am in the US on Pacific time zone so it is difficult to meet up in IRC due to time differential.
Any ideas appreciated.
