+Errors and diagnostics
+========
+
+ROMWBW tries to provide useful information when a run time or build time
+error occurs. Many sections of the code also have code blocks that can be 
+enable to aid in debugging and in some cases the level of reporting detail
+can be customized.
+
+Run time errors
+--------
+
+### PANIC
+
+A panic error indicates a non-recoverable error. The processor status is displayed on the console
+and interrupts are disabled and execution is halted. A cold boot or reset is required to restart.
+
+Example error message: 
+
+\>>> PANIC: @06C4[DFA3:DFC3:0100:F103:04FC:0000:2B5E] 
+
+\*** System Halted ***
+
+The format of the information provided is 
+
+@XXXX [-AF-:-BC-:-DE-:-HL-:-SP-:-IX-:-IY-]
+
+Where @XXXX is the address the panic was called from. The other information
+is the CPU register contents.
+
+Possible reasons a PANIC may occur are:
+
+- RAM Bank range error when attempting a read or write to a RAM disk.
+- Sector read function has not been setup but a read was attempted.
+- An interrupt vector has not been set up when an interrupt was received.
+- There was an attempt to add more devices than the device table had room for.
+- An illegal SD card command was encountered.
+
+The @XXXX memory address can be cross referenced with the build source code to identify
+which section of the software or hardware caused the fault.
+
+### SYSCHK 
+
+A syschk error is identified when an internal error is detected. When this 
+occurs an error code is returned to the calling program in the A register.
+A non-zero result indicates an error.
+
+Syschk errors may be reported to the console. Whether this occurs depends on 
+the value of the diagnosis level equate DIAGLVL. By default syschk errors
+are not reported to the console.
+
+If the diagnosis level is set to display the diagnosis information, then
+memory address, register dump and error code is displayed.
+A key differance with the PANIC error is that execution may be continued. 
+
+Example error message:
+
+\>>> SYSCHK: @06C4[DFA3:DFC3:0100:F103:04FC:0000:2B5E] FD
+Continue (Y/N)
+
+The format of the information provided is similar the PANIC report.
+
+@XXXX [-AF-:-BC-:-DE-:-HL-:-SP-:-IX-:-IY-] YY
+
+The syschk error codes YY is returned in the A register.

+### DIAG
+
+Progress through the boot and initialization process can be difficult to monitor 
+due to the lack of console or video output. Access to these output devices does
+not become available until late the in the boot process. If these output devices 
+are also involved with the issue trying to be resolved then trouble shooting is 
+even more difficult.
+
+ROMWBW can be configured to display boot progress with the assistance of additional 
+hardware. This take the form of an LED breakout debugging board connected to an
+8-bit output port. As the boot code executes, the LED output display is updated.
+
+To use a LED breakout board, it must be connected the computers data, reset and port
+select lines.
+
+To enable the DIAG option the following settings must be made in the systems .ini
+configuration file, where 0xnn is the port address.
+
+DIAGENABLE .SET TRUE
+DIAGPORT   .SET 0xnn
+
+The following table shows the ROMWBW process steps in relation to the LED display.
