Use VGA text instead of framebuffer #514
Description
Is it possible to use a text buffer instead of booting right away into a framebuffer? I am using a terminal Qemu (I have no other options available) and the only thing displayed is "graphic mode" with -display curses, so it would be very useful to switch instead to memory-mapped VGA text buffer mode.

As far as I know, the VGA text buffer doesn't exist when booting through UEFI. We try to minimize the differences between UEFI and BIOS booting, so we don't provide an option for this yet.

Ok I see, thank you for the response.

@bpisch,
Currently in modern machines the VGA text mode has become obsolete. The idea to output test is to use framebuffer. I know the difference of implement this, but my kernel is a nice example, perhaps...
