2.4.4PCI I/O Voltage Select (JP4)
The PCI Host board will always determine the PCI signaling level on the bus by set- ting all VI/O pins to either 3.3 V or 5 V. If VI/0 is set to 3.3 V, then the system will use
3.3V I/O signaling, likewise, if VI/O is set to 5 V, then the system will use 5 V I/O sig- naling. Some PCI host modules may only allow one of the options, while others may provide a jumper to allow the user to select the signaling level. Once the signaling level is selected, the remaining boards in the system must use that signaling level.

2.5Installing SODIMMs
The procedures for installing SODIMMs are described below. Please follow these steps carefully. You can install SDRAM memory modules using
(Small Outline Dual
1.Ensure that all power supplies to the system are switched off.
2.Tilt the SODIMM card just above the board and slide it into the housing card slot.
3.Push the module into the socket until the module gently snaps in. There should only be a slight insertion force to engage the module into the contacts. Make sure that the module and the housing are aligned and locked in place.
