5.1.1
Purpose of Dealer Script
The dealer script can give a diagnosis on a standalone DVD
player; no other equipment is needed to perform a number of
hardware tests to check if the DVD player is faulty. The
diagnosis is simply a "error" or "pass" message; no indication
is given of faulty hardware modules. Only tests within the scope
of the diagnostic software will be executed hence only faults
within this scope can be detected.

Contents of Dealer Script
The dealer script executes all diagnostic nuclei that do not
need any user interaction and are meaningful on a standalone
DVD player.
The nuclei called in the dealer script are the following (the
number after each nucleus name corresponds with the number
being on the local display when the nucleus is executed during
the dealer script):
Calculate and verify checksum of FLASH memory
Checks the I2C interface with the slave processor on
the display board
Checks the I2C interface to the basic engine
Checks the I2C interface with the NVRAM
Pattern test of all locations in the NVRAM
Pattern test of all locations in the SDRAM(s)
Check the I2C communication with the IO expander
and the audio DAC on the AV board
