Thank you for such a fast reply Smile. A postive FB and donation will be made. Can you please provide me link with how-to-do-it. Should it flash it from windows (simple click/open) or different?

I did try with "WinPlash" and there I got error message "corrupted interface descriptions in new BIOS file" Part table signature not found in the Interface. Error code -161

Here is prt srn.:

I also did try to run original flash from windows but I got message "BIOS image is same as BIOS rom, no update need at time" so I can reboot and run modified one.
