Hello again and thanks for the previous help,

I replaced my hvmloader with the one I compiled now. However, after
starting my virtual machine, I only get a white screen.
Note that the BIOS I used was written for QEMU, not Xen. Are there any
differences between the Xen bochsbios and the QEMU one?
Or may the problem be another BIOS? I do have the X11 library installed,
so I don't think that's the issue.
I only exchanged the rombios/bochsbios/bios or however you may call it,
not the vgabios.
Should I try compiling the hvmloader with the included bios and see if
it's a problem with the modified bios?

Greetings,
Niklas
