the download links on the first page no longer work
If you would like to download the drivers they can be found at

and info about enabling the power save is at

Make sure to download the PRISM_WinCE300.209.zip file and transfer the cab file that has the numbers 2336 I think to the PDA if you have Windows Mobile 2003. But don't worry too much because if it is the wrong version for that cab it will not allow you to install it.
But make sure you install the cab PRISM driver first w/o the wireless card in then install the Sandisk driver without the wireless card in then insert the card or reset if necassary.
Unlike with the instructions on the first page, if you install the PRISM driver last your sure to screw up and you will have to rename the PRISM dll file via activesync to remove it. I know I did 5 times, trying other prism drivers aswell.
