 630           to the terminal. This results in some non-visible but addressable characters,
 631           and is the case for most parallel LCDs. Other LCDs, and some serial ones,

 776           This allows you to replace the boot message indicating the kernel version
 777           and the driver version with a custom message. This is useful on appliances
 778           where a simple 'Starting system' message can be enough to stop a customer
 779           from worrying.
 780
 781           If you say 'Y' here, you'll be able to choose a message yourself. Otherwise,
 782           say 'N' and keep the default message with the version.

 794           An empty message will only clear the display at driver init time. Any other
 795           printf()-formatted message is valid with newline and escape codes.
