康柏以两种途径对 ROM BIOS 进行了修改,以向 YK2天冲刺。第一种修改是针对在日期变更发生时处于关机状态的系统,在变更后系统第一次开机时,可能会提供一个不正确的日期。康柏在 ROM BIOS 中增加了一个算法,在加电自检例程期间检查 RTC 日期,并进行计算。如果年份小于50则设置为20世纪。该算法允许 ROMBOIS 在变更之后系统启动时正确地增加世纪字节。第二种修改针对在日期变更时正在运行的系
Compaq made changes to the ROM BIOS in two ways to sprint YK2. The first change is for systems that are powered off when a date change occurs and may give an incorrect date when the system is switched on for the first time after the change. Compaq has added an algorithm to the ROM BIOS that checks the RTC date and performs calculations during the power-on self-test routine. Set to the 20th century if the year is less than 50. This algorithm allows ROMBOIS to correctly increase century bytes at system startup after a change. The second change is for a system that is running when the date changes
