Description of Tests
ROM
This test checks the software data (engine, boot, and setups ) stored in
Flash ROM on the Engine Board.
RAM
The RAM test writes to the microprocessor RAM space and verifies that the
write was successful. A failure of this test may indicate a problem with the
RAM or related circuitry in the Engine Board.
MARA
This test performs a read-write of the MARA registers and veri fi es that the data written can be
read back successfully. A failure of this test may indicate a problem with a MARA, related
circuitry or the Engine
Board.
Sound ROM
This test con fi rms that the Sound ROMs can be read by the MARA by performing a checksum
of
the Sound ROMs. The computed checksum is then compared to the stored checksum.
A failure
of this test may indicate a problem with a Sound ROM (U47), or the Engine
Board.
