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 jumper J45.

3.8 Flash EEPROM-Jumper J32

The S1668 uses flash memory to store BIOS data. It can be updated as new versions of the BIOS becomes available. The flash utility will guide you through the process step by step. If your system is functioning properly, you may want to forego updating your BIOS in the event the new one causes problems with your existing hardware and software.

J32 determines which type of EPROM is used. This jumper has been set to match the on board BIOS chip. The factory default for the S1668 is on pins 1-2.

Refer to chapter 6 for Flash EEPROM upgrade procedures.
