I added loader_color=3D"NO" and this didn't change anything. The u-boot = loader diagnostics is shown in black on white, then the FreeBSD boot = loader takes over, and the first thing, which it does is deleting the = u-boot loader diagnostics and then it switches the background to black = and the following is all white on black. What again is the purpose of setting the color scheme in the serial = console? I understand that something shall be set on the real screen, = now in a terminal window? Think about the poor people who like it green = on pink, and you change it to white on black, come on :-) Bets regards Rolf=
