The Y2K bug, what is called "millennium bug" or "2000 year bug", take place because the year after 2000 year is not recognize as the year marking method of the computer designed for take up two-digit number. This takes place because the RTC chip architecture of PC can not change the century information to the operating together with date. In this paper, we make an analysis about Y2K hardware bug of RTC in the IBM compatible PC, and make a Y2K compensation board in order to solve Y2K hardware bug. And the test results by various Y2K diagnosis program is bug before put in Y2K compensation board, but is not bug after put in Y2K compensation board. Therefore, we suggest a solution method for Y2K hardware bug of RTC in the IBM compatible PC.
