Could not use image

[robinsmidsrod]

Try to rebuild your iPXE with DEBUG=vesafb, that way you should at least know if your resolution is supported on the hardware, but your error seems to indicate lack of support for the image type, or that the image is not a proper pixel buffer. You might have used some funky PNG format not supported by iPXE. Try to use the "Export for web" feature to create your PNG file. That usually creates the most compatible files. Also, the last message seems to indicate that you are trying to boot the PNG image, which obviously seems wrong. I'm just assuming that it might be something wrong further down in your script.
