If the display whited out, entirely blued or appeared with a dialog box, a mass
storage problem is suspected. Try to perform the mass storage recovery
procedure.
If a message of "Will Shut Down in Five Seconds" is displayed in place of
"Initializing.." and the shutdown occurs, the PCA PCI DSP card fails in
starting up. The following message may be displayed before the shutdown
occurs:
"Fatal Error: Failed to Initialize DSP Driver":
or "Fatal Error: Failed to Initialize DSP":
This message indicates that the PCA PCI DSP Card doesn't work or is not
properly connected to the CPU Mother Board Assembly.
"Fatal Error: Failed to Update DSP Code":
If this happened, the PCA PCI DSP Card failed in writing DSP program into
flash ROM when the firmware was installed first or updated to the newest
version. A problem in the PCA PCI DSP Card or CPU Mother Board
Assembly is suspected.
