I have a PVR-350 and a separate video card installed into my myth box. When I boot up, the bootsplash shows up in the monitor attached to the video card. However, it is my eventual intent to remove the monitor and use the TV outoput from the PVR-350 exclusively. How do I get the bootsplash to show up on the TV instead of the monitor? |

I seriously doubt that it will be possible, as the pvr350 is not a true video card, but then again crazy hackers come up with ways to do stuff I couldn't envision all the time. |

Unfortuently I think the pvr-350 card needs to be inilized with the firmware before it is able to output correctly. To get a bootsplash to display you basically need to load the framebuffer with a image after the ivyTV driver had loaded the firmware. The framebuffer can be loaded with a simple DMA access over the PCI bus. But this would only produce a boot screen lasting from the ivyTV driver being loaded to when the X server starts. Which in the grand timeline of bootup is a very short time and not worth the effort. However when the machine is soft-rebooted the pvr-350 doesn't forget the firmware. So it could be possible to make lilo (or somewhere early in the boot up) copy a image into the pvr-350's frame buffer and it to be displayed correctly. But why stop there? Maybe lilo could load the firmware also? Seems like a hard task to perform. |
