3 HARDWARE INSTALLATION
The SB-3642 card is a 32-bit, 33/66 MHz PCI Local Bus Rev. 3.0 compliant interface
target device that may be inserted into any compatible slot. Note that this card is
capable of universal PCI signal and automatically defaults to 3.3V or 5V depending on
the host bus.
When installing the card, the following should be observed:
•
NEVER
insert or remove the card with the power turned on.
•
ALWAYS
take proper precautions to guard against static damage.
•
Use a wrist strap if available, or ensure proper static grounding by touching the
power supply cover
WITH POWER OFF
.
•
Insert the card at a slight angle so that the connectors first protrude from the
rear opening and then gently press the card into the motherboard connector.
Secure with proper hardware.
•
Make sure that adjacent cabling and wiring do not hinder the airflow around the
card.
This card is designed as a Plug-and-Play device and as such, there are no jumpers or
switches to be set for address and interrupt selection.
3.1 Hardware Configuration and Operation
The SB-3642
card utilizes the PCI interface, and the configuration for Plug-and-Play
PCI is performed by the operating system. During the initial power on boot process,
the system performs an enumeration of the PCI bus and allocates a resource
configuration that satisfies the card requirements. The system will save the
configuration information in the SB-3642’s
PCI configuration space registers. These
registers are configured at the factory to contain information that identifies the card
type, vendor, required memory sizes, and interrupt resources. When the driver loads,
it will access the configuration registers and identify how the system has configured
the card. After identifying each of the installed cards, the device driver will enumerate
each of the channels on the card and create a configuration structure that defines the
allocated address and interrupt. The end user does not need to know this information
if using one of the supplied C API libraries to operate the card.
