=== Firmware ===
[http://linux.junsun.net/intersil-prism/ Jun Sun's mini-HOWTO] explains how to update the firmware from Windows or Linux. Station Firmware 1.7.4 is recommended if you need support for WPA.

A firmware update package for the wireless function of this adapter is available from Lenovo.<br>
The available firmware version is 1.04.09.00 and is available [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-44289 here]. This updates the station firmware to 1.7.4

=== Linux WiFi driver ===
This adapter works with the '[[orinoco|orinoco_pci]]' driver as part of any recent 2.4 or 2.6 kernel. In addition the '[[hostap]]' driver can also be used.

The hostap driver supports WPA which the orinoco driver does not. WPA usage might require flashing the NIC's firmware, detailed intructions are available on [http://linux.junsun.net/intersil-prism/ this page].

=== Linux Modem driver ===
The Linux driver from [http://www.smlink.com/ SmartLink] supports this device.<br>
Latest version of this driver is 2.9.10 and supports both the 2.4 and 2.6 kernels.
The modem works with the "ALSA method" which is detailed in the README that
accompanies the SmartLink driver.

Note! Since kernel 2.6.12, there is a new ALSA mixer control "off-hook" which has to be
unmuted before the modem can be used, e.g. by running "alsamixer -D hw:1".
