============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0794 12-09-92 ============================================================================= POWER PREMIUM AND DALLAS SEMICONDUCTOR DS1255 PROBLEM: When running the application View386 from Lavenir Technology, the software displays the error message "software key not found". CAUSE: The Intel 82351 Local I/O EISA chip used on the Power Premium systems has a minor functional difference with the AT parallel port design which prevents it from working with the Dallas Semiconductor DS1255 Keyring. AFFECTED SYSTEMS: All Power Premium systems. SOLUTION: This is not a problem that AST can resolve. As a work around, the following options are available: 1) Install a third party I/O card. 2) Lavenir technology has been advised of the problem, along with a possible workaround which may be implemented through software modification. Contact Lavenir for a possible update.
