5.1 Introduction

The A82XDIAG.EXE diagnostic utility is a menu-driven program which allows complete testing of the OME-A-822PGL/PGH board. To run the diagnostic utility, change to the subdirectory used in the installation process (C:\OME-A-822 for example). Then type "A82XDIAG" <Enter> to start the application. These steps are shown below:

C:\>CD A822<Enter>

C:\A822>CD DIAG <Enter>

C:\A822\DIAG>A82XDIAG <Enter>

Aconfiguration file, named OME-A-82X.CFG is associated with the A82XDIAG.EXE program.The configu ration of the OME-A-822PGL/PGH board

is stored in this file. The stored information includes the board's I/O base address, interrupt number and DMA channel. Changes are not automatically saved to the configuration file, the user must select the save function to save any changes. When the A82XDIAG.EXE utility starts, it will automatically check if the jumper setting of

the I/O base address matches the value stored in the configuration file. If the addresses do not match, an error message will appear as shown below.
