Right, unfortunately gfxboot.c32 is making use of the COMBOOT API which
was deleted in 5.00 (it's done directly from 16-bit assembly so I didn't
catch it when doing the removal). Which means that it's missing large
parts of functionality, like being able to open and read/write files.
I'll take a look at fixing this.
