3.
Wait at least two seconds and set the switch back to
the Off position (toward the center of the board).
4.
Power on the Lion.
Real Time Clock (RTC)
The Lion features a real-time clock/calendar (RTC) circuit. The RTC can be set using the BIOS
Setup utility.
The Lion supplies RTC voltage in S5, S3, and S0 states, but requires an ex2.75 V to +3.3
V battery connection to maintain RTC functionality and RTC CMOS RAM when the Lion is not
powered. The battery connection can be made to either (but not both) of the following:
J12 external battery connector
J13 user I/O connector
Integrator’s Note:
There is no on-board battery. The Lion board will operate without a battery, but to save the date
and time, use a VL-CBR-4005 paddleboard (which includes a battery) or connect an external
battery to connector J12.
Expansion Bus
PCI
The Lion provides a legacy stack-down PCI connector on the bottom side of the board. See the
PCI sections of the
for a complete description of this interface. The
BIOS automatically allocates I/O, memory, and interrupt resources.
