Change logo in Phoenix BIOS – problem with aspect ratio

[menteith]

Hi all,

I have a Phoenix BIOS. My laptop is Lenovo ThinkPad 14. According to the documentation the logo should be 640x480. I did make my own logo, however, once I flashed it (I have tried a few times) it looks stretched. Why?

Please find attached the image I would like to have as a logo. I didn't change the resolution to 800x600 as requested since it would probably change aspect ratio. Let me know if you need a specific resolution, I will prepare the file then.


Thanks!

EDIT:

I tried to use Phoenix BIOS Editor, it opened the BIOS, showed several errors and when I clicked Splash Screen I get the following:
