The 162Bug package includes a set of hardware diagnostics for
testing and troubleshooting the MVME162LX. To use the
diagnostics, switch directories to the diagnostic directory. If you are
in the debugger directory, you can switch to the diagnostic
directory with the debugger command Switch Directories (

Manufacturing Test Process
During the manufacturing process for MVME162LXs, the
manufacturing test parameters and testing state flags are stored in
NVRAM. These strings are installed during the manufacturing
process and result in the product performing manufacturing tests.
None of these tests harm the product or system into which a board
is installed. Entering an ASCII break on the console port from a
terminal terminates these tests.
