Hello my friends!
Sorry for my English .
I see this request is still stuck,but I want a refresh the request and may be the
attached files may help to move the unlocking issue of this bios.
The attached .rar include the extracted original bios and his dump.
Also I tried to follow the steps of guideAccess-Advanced-settings-through-EFI-shell but after I do the changes and reset the system all variables is back to default values.
Thanks.

Hi!
I use this PC with the external screen.
When I try to boot in Legacy mode I can`t see the picture on display without pressing Fn+F5 key.
In the UEFI mode it`s not happen, all works automatically, but UEFI is very problematic for OS install.
In the Legasy mode the default video driver is: Intel V2137.
In the UEFI mode the default video driver is:Intel GOP.

If it`s possible to change default video driver to Intel GOP for Legacy mode in bios too?
