Win 2003 Small Business Server

Can anyone help me configure a Trendnet wireless network card
TEW-603PI.
Window 2003 installs allright, but to install Small Business a net work card must be installed and recognised before the Small Busines part will start installing – the subject card (Trendnet TEW-6i03PI)is not being recognized and and Small Business part can’t be installed.
Any suggestion by anyone would be appreciated what can be done to recognize the card – I posed the question to Trendnet, but get no answer from them.
