YEAR 2000 issue
All motherboard currently shipped from IWILL contain BIOS capable of handling
the year 2000 data correctly.
The IBM compatible PC utilizes a Motorola MC146818 compatible Real Time Clock (RTC)
chip to maintain the date and time. Unfortunately, the “century” is not manipulated by the
RTC. It uses 8-bits of information to report the year, and can only hold the last two digits of
a year in packed BCD format. For example, 1997 is reported solely as 97. Since the RTC also
contains non-volatile memory, IBM has specified a location in the memory to hold “century”
information. By combining the century data with the year data, software can obtain a full 4-
digit year. When the Year 2000 arrives, the RTC reports the year as ‘00’ and the “century” in
RTC memory will contain ’19.’ Combining the full 4-digit year yields 1900, not 2000. Any
application which compare dates, or uses relative dates to perform functions will see incorrect
dates.
All motherboards contain BIOS, which is one of the key ingredients to check for systems
designed to handle the year 2000. All motherboards currently shipped from IWILL
contain BIOS capable of handling the year 2000 date correctly.
Be aware that the BIOS capability alone does not ensure that the system will handle the
transition correctly. Other system components such as the operating system and application
software also need to be able to handle the year 2000 date, and recognize the date format from
other sources.
