Hacked up from the notes for AGMSRAMDiskDevice:

Viewing the Log:

If you want to see what's happening, and perhaps catch any error messages, you 
need to turn on debug logging.  Reboot the computer, then just when BeOS is 
starting to boot, hit the space bar.  A text menu should appear, pick the safe 
mode options from it, and then from the submenu, pick the Enable Console 
Debugging option.  Now debug messages will be appended to the file 
/var/log/syslog and will also spew out the serial port at 19200 baud (which is 
why they are slow).  You can watch the messages live by using the Terminal 
command "tail --retry --follow=name /var/log/syslog".
