[edit] Tips to improve boot speed
[edit] coreboot itself
- Make serial output the minimum amount of messages,because printing to the serial console slows down the 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)
