3.3 CMOS RTC

The TX chipset includes a Real Time Clock circuit. It provides the date and
the time for the system. Normally the life span of a RTC battery is 5 years.
If the battery for the RTC is low, it will prevent your system from
POSTing and you will not get a display. If this occurs, you will need to
replace the battery with another 3volt lithium battery(Duracell DL2032).
3.4 Speaker Connector Installation
The S1570 provides a 4-Pin header to connect the speaker. The speaker is
connected to pins 24-27 of jumper block J8.
3.7 Hardware Reset Switch Connector Installation
The RESET switch on your cases' display panel provides users with the
HARDWARE RESET function which is the same as power on/off. The
system will do a cold start after the RESET switch is pushed by the user.
The RESET switch is a 2 pin connector and should be installed on pins
22 and 23 on jumper block J8.
3.8 Flash EPROM-Jumper JP16
The S1570 uses flash memory to store BIOS programs. It can be updated
as new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step.
JP16 determines which type of EPROM is used. This jumper has been set
to match the on board BIOS chip. The factory default for the S1570 is on
pins 1-2. Depending on the type of EPROM used, some boards will have
JP16 on pins 2-3.
