Definition of Year 2000 Compliance
Our definition of year 2000 compliance is that a PC correctly stores & manipulates dates from the Twentieth to the Twenty-first century, including leap years, providing the date is properly supplied to the PC by any operating system, application or peripheral device interacting with it.

Role of Real Time Clock, CMOS and BIOS
The system date and time in our motherboards is maintained in a Real Time Clock which is given power backup from a battery.The year, month, day, hour and second are stored as 2 digit values in byte wide registers that can be read or written by software. This RTC storage format allows years to be represented by a value ranging from "00" to "99".

The component that contains the RTC device also contains battery backed CMOS memory used to store system configuration information. The system BIOS uses a byte of this CMOS memory to store the century portion of the year. When this figure is separated from the RTC it must be set and maintained by the BIOS.

The BIOS provides a set of services that can be used by operating systems and application software to set or retrieve the system time and date.The BIOS is capable of dealing with both century and year values, and therefore allows the operating system and application software to manipulate the year as a 4 digit value.
