Bios Mods -The Best BIOS Update and Modification Source

Hi to all! I want to ask you how to unlock this bios. When I connect an external graphic card in PCI-Express slot, it doesn't work (black screen at startup). Computer works only with integrated graphic card (Intel HD Graphics).

Motherboard Make/Model: Aspire MC605
Bios Version You Want Modding: P11.A4
Link To Official Bios Download: P11.A4

Thank you in advance!

I watched the tutorial that you sent me, but I'm afraid to do something wrong, can you help me ? :S

Hi mate,
I can affirm that Acer is the only one company didn't locked anything and all is moddable !
So if there are issues then may be there are incopatibility with this Video Card !
Let me know better if there is a Boot lock and error printed or different !
Have You checked the Slot PCIe to see the working state ?
Let me know
Regards

P.S. If there is no error at startup time I haven't any chance to find the issue !

I have a problem when I change default to user my checksum sizes are not the same anymore using bios tools from this link: https://www.bios-mods.com/forum/Thread-G...#pid145890

I think it is normal
When you set any value ,setup module would be changed, similarly bios body changed ,also .
So got different checksum is normal .

Here is my test mod with your dump bios.

Because all the threads scream that after changing the setting if the checksum is not the same dont flash. So i was checking.

I presume i have to set the bios_wr to open if i want to flash.

You can use a afuwin or a afudos that contain "gan" parameter  and use /gan to flash it .

Ok will try. Will let you know if the mobo died or works lol.
