[PATCH 3/3] [QEMU] Add BIOS splash image

Laurent Vivier
2008-12-16T15:20:43Z

This patch adds to qemu the function needed to display a splash image under
BIOS control through the firmware control device.

It adds a "-splash" option allowing to specify the picture file name (a .PNG)
to display. You can enable/disable a fade in, fade out and the bootmenu. The
time to display the image can be also given (in seconds).
