lenovo m73 reupdating the logo after bios upgrade

[kokodin]

Hello  edit box seems broken to me so i try to explain the situation without typing too much errors

i have 4 lenovo desktop computers delivered from non profit organisation, they are mandatory to have specyfic splashscreen for the entire contract time and it is not up yet we upgraded them from windows 7 to 10 and then installed the newest bios this summer (windows still during the initial promotion but that irrelevant) and bios update erased the custom splash screen foundation has inserted into the computers
even though lenove privides a logo update program the program does not seem to work in any provided version (dos, windows, or boot cd) i mean it compresses the image fine but later says it can't upload it because it has issues with the bios flash
i discovered bios update program and the bios logo update programs are two different ami flashers, one used to flash entire rom, the other used to flash selected part, being the logo but it  most likely fail to locate the specyfied area because lenovo made sme changes inside of the bios itself
is there any chance for any of yu to help with that?
