Hi David, Depending on your hardware, you can use a serial port as the console. If you are running on a server-class machine (from DELL or HP, for example), you should check the BIOS for this setting. Of course, you then need a serial cable and another machine to connect from. Also, depending on your equipment, using a serial port as console might disable the graphics/keyboard/mouse, meaning you get false errors/lack of errors. Another extremely low-tech solution is simply to use your phone to record the boot sequence, and replay and pause the video. Simply point at screen and start filming! I must admit to having done that a few times...

Some of these generate warnings/ errors on the console when the system boots. I'd like to capture console messages during boot, so that I can review them and fix things. > > > How? > > > TIA, > > David > > > p.s.
