### Diagnostic LEDs
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

8-bit output port. As the boot code executes, the LED output display is updated.
ROMWBW can be configured to display boot progress with the assistance of
additional hardware. This can take the form of a front panel LED display or
LED breakout debugging board connected to an 8-bit output port. Or it can
utilize existing platform status LEDS.
To use a LED breakout board, it must be connected the computers data, reset and port
select lines.
As the boot code executes, the LED output display is updated to indicate the execution progress.
To enable the DIAG option the following settings must be made in the systems .ini
configuration file, where 0xnn is the port address.
Platforms that have these capabilities built in have them enabled by default.
DIAGENABLE .SET TRUE
DIAGPORT .SET 0xnn
#### Front Panel display
The following table shows the ROMWBW process steps in relation to the LED display.
A LED front panel or breakout board needs to be connected the computers data,
reset and port select lines.
| **LED** | **RomWBW Processes** |
To enable this option the following settings can be made in the platforms custom
configuration file.
```
FPLED_ENABLE .SET TRUE ; ENABLE FRONT PANEL
```
Custom hardware can be configured with :
```
FPLED_IO .SET $nn ; USE PORT ADDRESS nn
FPLED_INV .SET FALSE ; INVERTED LED BITS
```
#### Platform Status LEDS
These status LEDs use preexisting status LEDs on each platform.
Enable using:
```
LEDENABLE .SET TRUE ; ENABLES STATUS LED
```
Customize using:
```
LEDMODE .SET LEDMODE_STD ; LEDMODE_[STD|SC|RTC|NABU]
LEDPORT .SET $nn ; STATUS LED PORT ADDRESS
```
The following table shows the ROMWBW process steps in relation to the panel
display.
