[sisela] ndiswrapper

I have just downloaded sisela-0.3. It boots perfectly on the old hardware I want to use. Only one problem - no ndiswrapper. Don't want to buy a new wireless card and the one I have is broadcom based. Can anyone advise an easy way to add that to the CD version (the floppy would be better). I would like to avoid building from scratch, if possible. I am using a Zenwalk (Slack) system and would not like to fool around with Debian. Help would be much appreciated. Best Regards, Larry
