I want to change the penguin logo that appears on boot. I looked into it and found this command:
pngtopnm nelogo.png | ppmquant -fs223| pnmtoplainpnm > logo_linux_clut224.ppm
But when I tried it I got this error message:
unrecognized option `-fs223'
pnmtoplainpnm: EOF / read error reading magic number
What did I do wrong? How can I replace the boot logo?
