#14516 closed defect (fixed)

Framebuffer mismatch: vga 320x400, drv 640x400!!!

Description

The summary contains a message from the log-file. The error occurs with 320x200 color mode. I use this mode with the bootloader for the educational project. So after MOV AX,4 INT 10H all goes very wrong. :-( I am using Virtualbox 5.0.2, the previous version 4.xx worked right. The host is Debian 8.1 Linux. The log is attached.

Please attach a bootable disk image with the bootloader, so we can reproduce this. Thanks.
