Linux Startup logo Modification

Linux Startup logo modification-Linux general technology-Linux technology and application information. The following is a detailed description. Target: Use a custom ppm image to replace/drivers/video/logo/logo_linux_clut224.ppm
In addition, you can delete the logo_linux_clut224.c logo_linux_clut224.o file to recompile logo_linux_clut224.ppm.
Ppm image generation:
# Pngtopnm logo_linux_clut224.png> logo_linux_clut224.pnm

# Pnmquant 224 logo_linux_clut224.pnm> logo_linux_clut224.pnm

# Pnmtoplainpnm logo_linux_clut224.pnm> logo_linux_clut224.ppm

I. Create a Logo image
[1] can be done with a tool, to http://registry.gimp.org/detailview.phtml? Plugin = Linux + Logo
Download a gimpplug-In glogo-1.3.tar.gz
[2] Open glogo-1.3.tar.gz and compile
Make; make install
[3] using some graphic tools to create three versions of the selected Logo image, in the format of bmp file, the size is 80x214 pixels, and the color is 214 colors (or lower than colors ), 16 colors, 2 colors
[4] Open The GIMP program of The graphic program group in The Linux graphic interface, open The generated three version logo image files, and then select The Build Linux Logo menu under The xtns menu, save the result to a file, such as the logo.

2. Modify linux_logo.h in the kernel/include/linux directory
Returns a result file generated in a lifetime, such as a logo. Its structure is
# If LINUX_LOGO_COLORS = 214
Data of 214 colors
# Endif
# Ifdef INCLUDE_LINUX_LOGO16
16-color data
# Endif
# Ifdef INCLUDE_LINUX_LOGOBW
2-color data
# Endif
Open linux_logo.h in the kernel/include/linux directory and you will find that the structure is the same. Copy the corresponding data (214, 16, and 2 colors) from the logo) to replace the original content in linux_logo.h. Then re-compile the kernel. The new kernel logo is a new image.
