[-=] Disclaimer [=-]

Upgrading your wireless card could potentially render it useless. Follow the
steps contained in the paper with caution.

[-=] About [=-]

This paper focuses on configuring wpa_supplicant and upgrading the prism
firmware in your wireless card if it currenty does not support WPA. All the
required tools are found within the Auditor Security CD. For this particular paper

download the following version of the CD auditor-150405-04.

.: II. Upgrading Firmware :.

(Both a SMC2532W-B and Senao NL-2511CD PLUS EXT2 were successfully upgraded
with the following instructions. The command outputs match those given by
both cards.)

[-=] Gathering info [=-]

The wpa_supplicant README states that a prism card requires at least station

firmware 1.7.0 or newer to work with WPA. While were are upgrading lets upgrade
the primary firmware also.

YOU MUST ALWAYS UPGRADE PRIMARY FIRMWARE TOGETHER WITH THE STATION FIRMWARE.
NEVER UPGRADE PRIMARY FIRMWARE ALONE.

First, begin by obtaining the current firmware version of the prism card.

root@computer:~# hostap_diag wlan0
Host AP driver diagnostics information for 'wlan0'

NICID: id=0x800c
v1.0.0 (PRISM II (2.5) PCMCIA (SST parallel flash))
PRIID: id=0x0015 v1.1.0
STAID: id=0x001f v.1.4.9 (station firmware)

The firmware of this wireless card is 1.4.9. It is very important you check the

NICID id number since it will decide on which firmware version you use. If
the NICID of your wireless card differs from the output above refer to
http://linux.junsun.net/intersil-prism/firmware/
to get the appropriate firmware
version.

The following files are used:

Primary Firmware - pk010101.hex
Station Firmware - sf010804.hex

[-=] Running the Upgrade [=-]

The upgrade will be done with the prism2_srec command. A test run is in order

before running the permanent upgrade to verify the image will be taken by the
wireless card.

The syntaxes are as follows:

For test run:
prism2_srec -v wlan0 <primary firmware> <station firmware>

For permanent upgrade:
prism2_srec -v -f wlan0 <primary firmware> <station firmware>


Test Run

OK.

Downloading to non-volatile memory (flash).
Note! This can take about 30 seconds. Do_not_remove card during download.

OK.
Components after download:
