How is any of this relevant to the OP's question?  I think it is,
somewhat, but you haven't made the connection.

Also, the OP doesn't appear to be looking for a better way to print
the welcome message, or to understand why the welcome message is
printing via int 0x10, but actually to remove the welcome message.

About the only legitimate case I can think of is if the BIOS is
redirecting output to a serial port and the presence of a welcome
message confuses an automated system on the other end of the serial
link that isn't expecting it.
