Tips to improve boot speed

coreboot itself

  • Make serial output the minimum amount of messages,because printing to the serial console slows boot a lot

Set the default console level to EMERG in Console ---> in make menuconfig

     Default console log level (0: EMERG)  --->
  • Do not delay boot with a bootsplash
  • Also the VGA option rom may delay the boot(but removing it removes the graphics not only during boot in some cases)
