This OID indicates whether this EISA port initialization entry writes its value directly or applies a mask before writing the value. An admin or engineer decoding an EISA initialization sequence needs this flag to know whether to interpret cpqSeEisaInitValue on its own or combine it with cpqSeEisaInitMask. For example, a value of useValueAndMask(2) means only the bits selected by the mask should be modified, leaving the rest of the port's existing bits untouched.
