Board Interfaces 41cPCI-36154.9 Switch and Jumper SettingsClear CMOS Switch (SW4)The cPCI-3615 comes with a Clear CMOS switch to reset theCMOS values to default. The switch is located on solder side ofthe board, under the "CE" logo. Press the switch to clear theCMOS and reset the values to default.VGA/GPIO Mode Switches (SW1, SW3)The VGA and GPIO 4~7 signals to J2 share the same pins andare selected by switch settings. SW1 is located on thecPCI-3615 component side (see “cPCI-3615 Blade Board Lay-out” on page 19 and “Removing the DB-3610CF DaughterBoard” on page 59) and SW3 is located on the solder sidebehind SW1. When the switches are set to VGA mode, theVGA signals are available to J2, and there are only four GPIOsignals connected to J2 (GPIO 0~3). When the switches areset to GPIO mode, there are eight GPIO signals connected toJ2 and VGA output to the RTM is not available. The switchesare set to VGA mode by default.Table 4-19: VGA/GPIO Mode Switch SettingsMode SW1 SW3VGA (default) All OFF All ONGPIO 4~7 All ON All OFFNOTE:NOTE:To enable VGA output on the RTM, Onboard VGA Output Selectmust be set to Rear in the BIOS Advanced Chipset Settings.SW1 SW3
