Hello, What do people think about having an early boot stage send some escape sequence to reset terminals to some sane default terminal settings? Often firmware or other causes will leave an unreadable font color or break line feeds, and the terminal tends to stay that way until a shell clears and resets the screen. If a shell can do it, surely loader could do it (or even earlier, if it is not too complex). To my knowledge it should be just a matter of printing some escape codes before starting the normal boot menus when using a serial console. I believe this is already done when the console is set to vidconsole or efi. Thoughts? Suggestions? -- Ryan Moeller iXsystems, Inc. OS Developer Email: ryan@iXsystems.com
