I just found a great logo for rockbox which was done by S3TUP so, big Thanks to him! and I thought it would be great if we used this one when rockbox boots, so I did a little patch and everything works like a charm.

This is the image which will be shown when rockbox boots:

Get the two images for your iPod color and/or video here:
iPod Color: rockboxlogo.220x68x16.bmp
iPod Video: rockboxlogo.320x98x16.bmp

and get the Patch from here: full_screen_logo.patch which is required for placing the image at the top edge of the screen, and to remove the version label from the bottom, so only the background is shown.

You can always use my prebuild binaries (look for rockbox-jbuild-YYYYMMDD.tar.gz) for both iPod types, but please note that these binaries have been patched with the Scroll margins, Custom status bar height, Custom font height and so on, so your old themes my not look as good as before because this patches have been optimized for my themes :)
