standard ISA RTC functionality, the integrated RTC also includes the 
date alarm, century field, and other enhancements for compatibility with 
the ACPI standard. 

5) Hardware monitoring subsystem for managing system/ motherboard 

voltage levels, temperatures, and fan speeds 

6) Full System Management Bus (SMBus) interface. 
7) Two 16550-compatible serial    I/O ports with infrared communications 

port option. A third serial port is available to be dedicated to the IR 
interface.
