Timers
Can someone clean up this bit under Timers, please? "You can see some of the 8086 compatible timer chips like 8253/54 also they are the same have three independent timers internally but 8254 can work with higher frequencies and is used to generate interrupt like Memory refresh interrupt ,Time of day TOD interrupt and the last one is used to generate the speaker frequencies."
