i would like to see you be able to change the boot screen, for the WB1.3 skin having a loading screen of kickstart or workbench floppy would be cool

You go here: Archive :)

For some reason that source is MagicEyes not GPH - although it does have logos for MagicEyes in it though... :(

@triton: I think he meant me . . .sorry

@Quiest: I did some research at U-Boot, came up with this:

First bootscreen (Dark Gray) is compiled into U-Boot MTD image.

Second splashscreen (Green) is in both U-Boot image and Linux image.

U-Boot starts a framebuffer, dumps first screen to it. It then checks for Firmware upgrades through FTP, SD etc, if none are present it starts a second framebuffer and dumps second splash screen to it. Then it switches frame buffers and loads Linux

When Linux loads, memory from first frame buffer is released and Linux starts a frame buffer, loading it with it's own copy of second image and switches to it.

Then U-Boot terminates and that memory is released to pool.

Basically we'll have to recompile both U-boot source and Linux source with our bitmaps in.

U-Boot states only 225 distinct colors allowed, otherwise will crash, reason not specified
- or I got tired of reading the manual :D

So, yes it's possible to replace the boot screens, not likely immediately.
