Bios Mods -The Best BIOS Update and Modification Source

Hi, can anyone teach me how I can edit the splash screen for the BIOS of this specific laptop model? I really want to personalize my laptop and I was hoping you guys can help me with it. And with the inevitable arrival of another BIOS update to mitigate the Spectre and Meltdown flaws, I would prefer to learn how to do it myself so I wouldn't have to bother you guys with another request if ever another BIOS update comes up. Currently, this is the latest version of my BIOS that's available. https://cdgenp01.csd.toshiba.com/content...f6v140.exe
Any help on how I can customize the splash screen for this is very much welcomed and appreciated as I currently do not have any knowledge in editing it. A full step by step guide would be great and the do's and don'ts of it like say how to backup or should I backup the current BIOS before doing anything.

if you can give me the .rom or .fd or whatever file is in the temporary directory under windows when you run it i can probably find the logos and figure out their file type and attempt a mod if its not an ami bios or aptio bios for laptops i cant gurantee but i can definitely try til it does work if you have a good way to recover from possible brick.
