hope your machine is OK after the exercise.īe forewarned. I kept poking at all the info provided at the Dell forum and by the end of the workday I was relizing it's not a solution - I have inquiry in there to see what experience people had because there are people saying it 'worked!' but when I looked those patches up they are even older than my A10 patch level! So, sorry you headed down that path with my misdirection. Sorry for not getting back on R194010 and R194011. I updated to the A15 BIOS but still I have the conflict with the two PCI devices, as you also list here. My BIOS before my work yesterday was at A10. My machine is an Optiplex 755 is a Core 2 Duo E8400 3.0 GHz - I have installed Windows 7 Professional (I am verifying that the Vista drivers work for those of us in Windows 7 land - the posters at the Dell Community forum seemed to be indicating so.) Take a look at the 'Compatibility' section - there we are, OptiPlex 755! And yes, they are for Vista, but they work for Windows 7, too - at least they have been reported to have worked for the posters at the Dell forum referenced above. Intel AMT HECI, v.3., A01 (like the first in the list of results, for R194010. Search for R194010 (and R194011 after that) using the search box in the upper right of the Dell support page.Click on 'Drivers and Downloads' button at top.I have installed 64-bit, but this will work for both of us. I have an Optiplex 755 Core 2 Duo E8400 3GHz on which I have installed Windows 7 Professional from scratch (formatted the hard drives completely). There was this post at that prompted the investigation.

They do care about us, stephenscott (sort of)! Thanks to finding your note through searching for my own needs, I found you and hopefully the answer!
