  GRAPHIC CARD SUPPORT
  ====================
  Advanced Civilization requires an SVGA graphics card that
  supports 640x480 with 256 colors.  The code auto-detects what
  type of card you are using and then based on that auto-detection
  initializes the low-level graphic routines.  This auto-detection
  logic generally works but there are some cards that can confuse
  the auto-detector.  
  
  If you happen to be one of those lucky ones whose machine
  confounds the detection code, you will know it because as soon as  
  the character-based game banner goes away the screen will do
  strange things, the program may crash and usually the only way to
  recover is to reboot.  All is not lost.  Try running the game
  using the following command:
  
       advcivil /V1
  
  That's a one following the V and not an I.  This command line
  switch forces the game to use VESA drivers instead of the chipset
  specific drivers.  If the game runs properly using this switch
  you may either continue to start the game in that manner or you
  can start the game as follows:
  
       advcivv1
  
  This is simply a batch file the runs the game with the /V1
  switch.  The /V1 switch assumes that a VESA driver is present in
  your machine, either built in to the graphics card or as a
  separately loaded driver.  If your VESA support is not built-in,
  refer to your graphics card manual as to how to load the VESA
  driver.
  
  
  SOUND SUPPORT
  =============
  The sound drivers that are used by the game can be changed after 
  installation by running the setsound program as follows:
  
       setsound


  COMMAND LINE SWITCHES
  =====================
  The game supports some command line switches.  A list of these can be
  seen by running the game as follows:

       advcivil /?


  The switches are:
       /?      - List the switches
       /NS     - Disables the sound drivers
       /NT     - Disables showing of opening titles
       /SRD[x] - Enables the self running demo
           [x] - number of players 3 to 8 (default 8)
                 (Pressing Escape during the demo will eventually exit)
       /VT     - Prints video chipset found by auto-detect code
       /Vx     - Force game to use a specific video chipset
                 (Do not use any number for x other than 1 without spe-
                 cific directions from Avalon Hill Tech Support)


  DEBUGGING CODE
  ==============

  A decision was made to leave a few debugging traps in the game. The 
  nature of the bugs these traps are designed to catch will cause a 
  gradually degradation of the game.  By trapping the bugs when they 
  occur we accomplish two things.  First, we make you mad immediately 
  without having to wait for the game to fall apart and second, the game
  files are in a state where we can relatively easily find and fix the 
  problem.  
          
  Advanced Civilization has been thoroughly tested, however there are 
  always some bugs that get through the system.  So, while we do not 
  expect you to ever run across these traps, here's what to look for.

  There are 3 specific checks left in the game.  The first checks for 
  invalid moves in tokens and gives the error message "Exceeded valid 
  moves in xxx. REPORT THIS!". The game will have exited to DOS at this 
  point. 

  The second looks for invalid ship movement and gives the error message 
  "Ship #x has yyy ShipMovement units in zzz." The game will have exited 
  to DOS at this point.

  The third check verifies the primary game structures and if an error is 
  detected puts up a gray screen of numbers with some combination of 
  Token Error, Ship Error, City Error or Card Error at the top. Pressing
  the CONTINUE button at this point may take you to additional error 
  screens or exit you to DOS.

  Again, we do not expect you to ever see these errors messages but if 
  any of the above do happen, first vehemently curse the programmer.

  Now that that's out of the way, make a copy of the files "savgamea.dat"
  and "savgameb.dat" and assuming that you are still interested in 
  getting this bug fixed eventually, send the files to Avalon Hill 
  through any of the online services listed in the manual.
