Limit the color of the PNM picture to 224:

Pnmquant 224 NAME3.PNM > NAME4.PNM

Convert PNM images into the PPM format we need:

PNMTOPLAINPNM NAME4.PNM > logo_linux_clut224.ppm

Copy the file to the "drivers/video/logo/" directory in the kernel source code

Replace the original "logo_linux_clut224.ppm" file. Delete logo_linux_clut224.c at the same time
