A lot of distros set the 'quiet' option to _keep_ the kernel from spewing messages at boot. Ubuntu sets "quiet splash", for instance. Going into the grub menu and killing the 'quiet' and replacing it with 'debug' is a good place to start. earlyprintk=vga can also help if things are still blank at that point. I thought we used to have an earlyprintk=efi, but it seems to have vanished at some point. But, you've got a bit of oddball hardware. It's from the _far_ extreme end of 32-bit-only hardware. The fact that it had Windows on it isn't a great sign. There could be a BIOS bug that trips Linux up but Windows is perfectly happy with. There was definitely a sad period of time where folks were not interested in fixing issues like that.
