Re: Changing MAC address in ThinkCentre M910q BIOS
I was able to fix the issue by extracting the entire Gbe region and reflashing.

Re: Changing MAC address in ThinkCentre M910q BIOS
I think I may have messed something up. I used a hex editor to modify the MAC address at 1000-1005 but I'm getting PXE and NVM errors. I attached the PXE error. After the PXE error I can boot to the OS and the new MAC is recognized and Intel ATM is working. I was able to disable PXE boot to make the error go away. I'm getting an invalid NVM checksum error when booting the Debian installer.
I'll try extracting the entire Gbe region like SMDFlea suggested and reflash....Leave a comment:

Re: Changing MAC address in ThinkCentre M910q BIOS
I opened the bin file using a hex editor and I see the MAC address at 1000-1005. I see FF at 2000-2005. I’ll try replacing 1000-1005 and reflashing. I assume I can leave 2000-2005 alone.Leave a comment:

Changing MAC address in ThinkCentre M910q BIOS
I have two Lenovo ThinkCentre mini I flashed the same .bin file on both devices and I noticed that the MAC address is the same for both devices. I plan on using Intel AMT on these devices, so the MAC will need to be changed at the BIOS level not the OS level. Is there a way to do that with a tool, or is modifying the .bin file the only way? -
Re: Request: Lenovo M910Q IQ2X0IH
bump. I found a BIOS from another thread with the same motherboard model and tried cleaning the ME and copying the DMI from the original BIOS but now the SATA SSD isn't being detected and it still shows the model/SN of the BIOS I downloaded from another thread.Leave a comment:

Re: Vizio M65-C1 won't power on
The replacement power supply did not fix my problem, and I can't explain that. When I saw the YouTube video with the exact same symptoms I figured I would give it a shot and it worked in my scenario. The set is still running great to this day....Leave a comment:

Re: Vizio M65-C1 won't power on
Hey I wanted to update everyone and let you know I was able to repair the power supply by following this YouTube video [url]https://m.youtube.com/watch?v=fesJGOLurBg[/url]Re: Vizio M65-C1 won't power on<br /...JGOLurBg[/url]Leave a comment:

Re: Vizio M65-C1 won't power on
How would I go about doing that? Do I need to purchase a resistor? Sorry, all of this restistor talk is completely foreign to me.Leave a comment:

Re: Vizio M65-C1 won't power on
Both power supplies read 19V on +12V_A when either power supply runs solo. Furthermore, both power supplies read between 6V~13V when the old or new main board is connected. This leads me to believe the issue is not power supply or main board related or I'm not getting a good reading from the power supply when the main board is connected. If I put a meter on the main board, I get the same fluctuation from the connection coming from the power supply 6V~13V.Leave a comment:

Re: Vizio M65-C1 won't power on
The PN on IC9111 on my original power supply is:
SP601BE
CF2A871.1
20150129
Keep in mind at this point I have purchased a replacement power supply and main board...Leave a comment:
