900c and a Dlink DWL-650 P

I downloaded the driver for this card from HPCFactor and don't understand how to install it. I'm fairly computer literate, just not handheld literate. I do have MS Activesynce 4.5 installed and understand how to move files and sync, but when I open the driver files (unzip them) all I see is the following:
PRISM~4
PRISMCFG
PRISMINS
PRISMIOC
PRISMNDS
PRISMRES
PRISMSTA

Note: There are 9 PRISM-named files in the driver named 3-00-08-0236_WINCE400. This list of files came from the first unzipping. I am assuming each of the nine files represents a different build of the wireless card as they all have similar file names. Below I've included any info I thought may help.

What am I supposed to do with these files?

The numbers on the back of my card are:

FCC ID: KA22003070026-1
Node ID: 000D8856E8BF
S/N: H2DT23A039819 V.P1

Furthermore, when I push the card in and it asks for a driver, what do I type??

Thanks, Brew

The file name is PRISMNDS. The card's light will flash for a short while and then nothing further. I did not succeed in making it work on MP900C though somebody did succeed on J720 with some hacks. I even tried quite a few drivers from EagleTech, Linksys, Senao, and so on. The problem is that P1 uses PRISM 3 chipset.

A download of the firmware into the flash might/might not help the card work with Intersil's reference driver.

don't unzip it.. just copy the cab to the 900c and install it.

btw, which OS revision do you have?
