I just checked the source and there is a check to test for the presence of a monochrome card and even the presence of a two screen ([C,E,V]GA + monochrome) setup and it looks ok to me at a first glance, unless your system doesn't properly provide the 6845 CRT controller status, which is used for part of that test. I can't test this right now on real iron, as all my systems are in storage at this time, but it works (almost) ok both in vDOS as well as in a VirtualBox setup of FreeDOS 1.1 (though here it switches to a 40 column mode, but cursor and all is still visible/functional)...

Hi Eric, Nice to see you're still around fixing stuff :) There is one little inconvenience I experienced with MODE, that I reported earlier this year while working on my Svarog86 distribution. It relates to MODE executing 'MODE MONO' without checking that it will actually work (leading to screen loss on CGA systems). Here's the original thread: http://freedos.10956.n7.nabble.com/FreeDOS-ODIN-and-8086-compatibility-td22460.html Mateusz On 15/12/2015 18:30, Eric Auer wrote: > > Hi FreeDOS fans :-) > > Bob Ouellette has found a bug in how FreeDOS MODE in the 2005 > version fails to correctly set the number of bits per "byte" > for the serial port at lower to middle baud rates.
