This variable defines a command string that is automatically executed when the initial countdown is not interrupted. The contents of this variable are passed to the Linux kernel as boot arguments (aka “command line”). If set to yes, an image loaded using the rarpb, bootp, dhcp, tftp, disk, or docb commands will be automatically started (by internally calling the bootm command).Ī decimal number that selects the console baudrate (in bps).
