4. Notes on CD CRAFT use
The following describes the items that require attention when using CD CRAFT.
The summarized contents of the manual described here are the minimum items that
require your understanding. For further details, refer to the manual.

* The GD Writer and GD-R media are markedly delicate items compared to the 
  earlier CD-R. Be sure to pay full attention to this during use.


4.1 GD Writer handling
  (a) Place the drive in a stable location where it is not subjected to 
      vibrations.
      Do not place a hard disk, etc. on top of the GD Writer's enclosure.
  (b) Connect the GD-R drive only, disconnecting other SCSI devices as far as 
      possible. 
      Also check the cable length, and the conditions of the cable and 
      terminator connections.


4.2 GD-R media handling
  (a) Before writing, use a blower to blow away dust adhering to the media.


4.3 System settings
  (a) Use the newest ASPI manager and SCSI drive
  (b) Set "automatic insertion" to OFF
      If the GD Writer is recognized as a CD-ROM device, set "automatic 
      insertion" to OFF on the Device Manager's CD-ROM device properties menu.
  (c) Check that "disconnect" is ON
      As in (b), check that "disconnect" is set to ON on the CD-ROM device 
      properties menu.


4.4 Conditions for executing the program
  (a) Close all other applications
  (b) Do not start tasks that run in the background, such as Screen Saver, 
      System Agent, Active Channel, etc.
  (c) Do not connect to a network


5. Notes on disk creation
When creating a self-starting disk in the device with the final BOOT-ROM,
all the following items must be satisfied.

  (a) A special IP must be located in each system area for single-density and 
      high-density use.

  (b) The first read file entered in the IP should be located at the outermost 
      track of the high-density area. (*2)
      The last track must therefore be a Mode1 track.
      Please refer to the sample script "sample.scr" provided with this tool.
      For more detailed contents, refer to the IP documentation provided with 
      Dreamcast_SDK.

  *1 The first character of the name of the first read file must be a numeral 
     (0 to 9), and the filename must conform to the 8.3 name format.
  *2 From CD CRAFT Ver. 2.27, a function for self-locating the first read file 
     at the outermost track is provided.

<Note>
The above items are the minimum required items when creating a disk capable of self-starting.
This is no guarantee that this can be the master release.
Do not fail to check the following items when the master is delivered.
  (a) Items specified in the IP
  - Product code
  - Application maker ID
  - Corresponding area code, ... etc.

  (b) The following PVD definition contents and compatibility with the actual 
      file
      Identification data and actual file should be defined for the disk's 
      single-density area.
  - Copyright file identification data
  - Abstract file identification data
  - Bibliographic file identification data


6. Limit of System Function
