Storage drivers for Netware 5

We adquire a Proliant ML350 G3 Server to make a transition from a Netserver E50. We have Netware 5. Now when we tried to install Netware 5 in the Proliant Server, it doesn't recognize the currect drivers. We already download drivers from Service Pack but they doesn't work.

Please I need your assitance to know what to do? Thank you in advance
