Battery backed clock (RTC)
An AT compatible date/time clock is located within the chipset. The device also contains a CMOS static
RAM, compatible with that in standard ATs. System configuration data is normally stored in the clock chip's
CMOS RAM in a manner consistent with the convention used in other AT compatible computers.
Connect an external Lithium battery to J24. Make sure to use the correct polarity!
The battery-backed clock can be set by using the DIGITAL-LOGIC AG SETUP at boot-time.
