If one wants to have the boot code send the initial stuff to both the serial and VGA, one should use echo '-Dh -S115200' > /boot.config but the option -Dh does not seem to be mentioned in boot.config(5) ?
Hello, From boot.config(5) : A valid format of this file is to put BIOS drive number, a controller : type, a unit number, a partition, a kernel file name, and any other valid : boot(8) option <...> Have you checked boot(8) man page? Ok to close the ticket? Thanks, Maxim
