1. PC internal clocks. Even new motherboards are typically stuck with a brain-dead century rollover problem: You may have to turn the PC off and then on immediately after 12:01 AM on January 1, 2000, in order to inform the BIOS that the clock is off by 100 years. <sigh> This will correct the problem if you have a recent motherboard BIOS. You can go to the IBM Year2000 website (http://www.ibm.com/ibm/year2000/pcs/assess.html) and download the "PC Evaluation Tool" to verify this for yourself.
2. The Operating System. This seems to baffle many people. Just because the hardware is Y2K-ready, that does not mean that the *computer* is Y2K-ready. Users of IBM DOS2000 or PCDOS7 with the Y2K patch are in good shape; users of Linux are in great shape (Unix variants are expected to have a Y2038 problem only). Users of OS/2 can get in shape by using the appropriate Fixpack. (FP6 or higher for Warp4; FP37 or higher for Warp3.) Note t
