Configuration Var 'MS' throws an error?

Team,

When I debug=5 MS 2004 or V8i I get an 'kind of' error that the definition of 'MS' from the msconfig.cfg

The debug shows that 'MS' was not defined and I have not found where in config to resolve it.

This happens in vanilla installs before any custom config is applied.

 

Has the MS variable in the msconfig.cfg been made redundant ?
