hi,
the attached patch fixes the issues with widescreen resolutions for me
when using -std-vga.
in vgabios/vbetables-gen.c I changed the video memory from 8MB to 16MB
which is sufficient for resolutions up to 2560x1600. I've also added
some more video modes (up to 2560x1600) with 16, 24, 32bit color depth
each and I've removed the duplicate for the 1280x960 mode.
in qemu/hw/vga_int.h I've adapted the maximum resolution accordingly.
you can download the updated vgabios from http://www.wina.at/vgabios.bin
I would appreciate any suggestions, comments and of course testing.
@Arne Brutschy: could you please test the 1920x1200 resolution with your
setup?
cheers,
Andi
