Installation

2.4 Hardware Installation Outline

PCI configuration

The PCI cards (or CompactPCI cards) are equipped with a Plug
and Play PCI controller, it can request base addresses and
interrupt according to PCI standard. The system BIOS will install
the system resource based on the PCI cards’ configuration
registers and system parameters (which are set by system BIOS).
Interrupt assignment and memory usage (I/O port locations) of the
PCI cards can be assigned by system BIOS only. These system
resource assignments are done on a board-by-board basis. It is
not recommended to assign the system resource by any other
methods.

PCI slot selection

The PCI card can be inserted to any PCI slot without any
configuration for system resource. Please note that the PCI
system board and slot must provide bus-mastering capability to
operate this board well.

Installation Instructions

1. Turn off your computer

2. Turn off all accessories (printer, modem, monitor, etc.)

connected to your computer.

3. Remove the cover from your computer.

4. Setup jumpers on the PCI or CompactPCI card.

5. Select a 32-bit PCI slot. PCI slot are short than ISA or

EISA slots, and are usually white or ivory.

6. Before handling the PCI cards, discharge any static

buildup on your body by touching the metal case of the
computer. Hold the edge and do not touch the
components.

7. Position the board into the PCI slot selected.

8. Secure the card in place at the rear panel of the system.
