Trilogy 3 MPCI
M3AWEB/56GA
Product Specification
What’s Not Supported
• The 802.11b firmware does not currently support a low power mode of operation
(< 20 ma). For Idle mode, it removes power to as many circuits as possible, but
the current level of firmware implementation prevents the ISL3874A controller
from using a 32 KHz low power oscillator for sleep mode. Since the controller
and clock will always be active the driver does not require wake-up/resume
operations (although the adapter will consume as little power as possible when
there are no receive, transmit, internal (roam) or host activities in progress.)
• Wake-On-LAN operation is not supported for the 802.11b section of this product.
This is due to the fact that the Intersil chipset does not support 3.3VAUX
detection.
• A hardware “Radio-Disable” switch is not supported for the 802.11b section;
however a software-implemented function is provided to disable radio
transmissions.
• There is no output pin to display 802.11b Activity status via an LED. Displaying
Activity Status is not supported with the current revision of the Intersil chipset and
firmware at this time. Future plans for support of this feature in Intel’s 802.11b
MPCI product are TBD as of Revision 1.2 of this document.
