Would like to run "black on white" software on a DOS machine with an LCD screen, so am wondering if there are any TSR tools, or similar, for inverting the screen. I believe it is grey scale VGA, not monochrome.
It's a HP Omnibook 300, if that matters.
I had a look at Simtel (I believe) a while ago, but could not find anything that worked.
Addition: I am running DOS only, not MS Windows.
ansi.sys does not seem to work, I believe the program handles the graphics directly by itself. The program also does not have a way to change the colours. Giving the command
mode mono before running the program does not make a difference to the program (but it does mess up the display of the battery level, which is something special apparently using the CP437/850 block graphics). The machine does not have any BIOS options for changing the display in any way. In fact I am not sure it even has a standard BIOS.
