2.6 This product is “YEAR 2000 CAPABLE”
This DIGITAL-LOGIC product is “YEAR 2000 CAPABLE”. This means, that upon installation, it accurately
stores, displays, processes, provides and/or receives date data from, into, and between 1999 and 2000, and
the 20. and 21. centuries, including leap year calculations, provided that all other technology used in combi-
nation with said product properly exchanges date data with it. DIGITAL-LOGIC makes no representation
about individual components within the product should be used independently from the product as a whole.
You should understand that DIGITAL-LOGIC’s statement that an DIGITAL-LOGIC product is “YEAR 2000
CAPABLE” means only that DIGITAL-LOGIC has verified that the product as a whole meet this definition
when tested as a stand-alone product in a test lab, but dies not mean that DIGITAL-LOGIC has verified that
the product is “YEAR 2000 CAPABLE” as used in your particular situation or configuration. DIGITAL-LOGIC
makes no representation about individual components, including software, within the product should they be
used independently from the product as a whole.
DIGITAL-LOGIC customers use DIGITAL-LOGIC products in countless different configurations and in con-
junction with many other components ans systems, and DIGITAL-LOGIC has no way to test wheter all those
configurations and systems will properly handle the transition to the year 2000. DIGITAL-LOGIC encourages
its customers and others to test whether their own computer systems and products will properly handle the
transition to the year 2000.
The only proper method of accessing the date in systems is indirectly from the Real-Time-Clock via the
BIOS. The BIOS in DIGITAL-LOGIC computerboards contain a century checking and maintenance feature
the checks the laest two significant digits of the year stored in the RTC during each BIOS request (INT 1A) to
read the date and, if less than ‘80’ (i.e. 1980 is the first year supported by the PC), updates the century byte
to ‘20’. This feature enables operating systems and applications using BIOS date/time services to reliably
manipulate the year as a four-digit value.
