I have set fade in/out, display time, and logo with VBoxManage. The .vbox file contains:
<BIOS>
<IOAPIC enabled="true"/>
<Logo fadeIn="true" fadeOut="true" displayTime="10000" imagePath="C:\Users\nikberry\VirtualBox VMs\Circe\elf bios A.bmp"/>
</BIOS>
Imagemagick shows: C:\Users\nikberry\VirtualBox VMs\Circe\elf bios A.bmp BMP 640x480 640x480+0+0 8-bit sRGB
But it shows the default logo, not for 10 seconds, and doesn't fade in or out. Any ideas what I'm doing wrong?
