Update Dell Optiplex 760 BIOS?
It seems that the A02 BIOS for Optiplex 760 is flawed, and pretty much incapable of running windows 7. The K2 doesn't seem to be a great way of updating the BIOS seeing as the PE is based off of windows 7, and so I was wondering how to otherwise install Dell BIOS updates?
I created a windows PE bootable USB and executed the file O760-A08.EXE as suggested here: http://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?c=&l=&s=&cs=&DriverId=R277162#3DOS
When I restarted the computer, the initial splash page indicated the system was still A02. What am I missing?
I was able to have more success by getting the .wim for windows PE 2.0. The Vista version.
A13 is actually the latest version.
I boot to PE and run the executable. It prompts asking if I would like to replace A02 with A13. I say yes. It lets me know that it is going to replace it and reboot. I say sure, yes thank you.
After the popup windows go away, I am back at the cmd prompt with nothing else happening. The computer does not restart. This seems a bit troubling as I would expect the computer to actually restart.
If I manually restart, I find that it does indeed try to upgrade the BIOS with the message "Attempting BIOS update -- this may take up to 10 minutes"
One attempt took about 20 minutes, is says:
BIOS Update Failed!
ME Firmware Update Successful
Could Not find the firmware image in memory.
I tried a different BIOS version with the same results. I have no idea what is going on here.
I used the CCTK to modify a Vista PE. I put that PE on a flash drive and booted to it. I executed the O760-A13.exe file from the command prompt, clicked ok twice. I then closed the cmd prompt window.
I stepped away for a moment, and when I came back I found that it had indeed upgraded the BIOS to A13. I will be attempting to replicate this as we get more 760s in, but this seems to be workable enough.
