For example, in the INF spec 1.25, the following is defined for the protoco= ls section : The formats for entries in this section is: gEfiProtocolCName [ | FeatureFlagExpression] ## Usage comment When a FeatureFlagExpression is present, if the expression evaluates to TRU= E, then the Protocal entry is valid. If the expression evaluates to FALSE, = then the EDK II build tools must ignore the entry. The following is an example of the [Protocols] section. [Protocols] gEfiDecompressProtocolGuid gEfiLoadFileProtocolGuid Does anyone have any examples showing the use of a FeatureFlagExpression ? Thanks,.....Frank
