Y2KANSWR.COM & Y2KREPLY.COM
Y2KANSWR.COM & Y2KREPLY.COM will check for the year reaching 2000, and changes the century byte in the RTC from "19" to "20" once the year reaches 2000. Both utilities intercepts the 1AH function 04h BIOS Read Real Time Clock Day Time of Day Services, and puts the correct century byte field each time that Interrupt Service Routine is called. The two solutions for the Year 2000 situation differ only in two aspects, Y2KANSWR.COM checks for the year changes once after the Day Rollover Flag has been set, however, Y2KREPLY.COM checks for the year changes each time that INT 08H (18.2 times per second) is called. Once they recognize the year change both immediately write the proper century field to the BIOS. There are a few utilities that check for Live RTC Rollover (Direct I/O), which Y2KREPLY.COM answers to.
This Terminate and Stay Resident (TSR) program uses less than 500 bytes of memory space to accomplish the required tasks. The evaluation software is free for personal use; however, business's need to purchase a site or users license. The TSR's work with DOS, Windows 3.X/95/98.
