Replacing disk array controller

[Pierre de Witt]

I have a Compaq Proliant ML530 server running RH AS 3.
The disk array controller is a Compaq Smart 2 SL and I want to replace it 
with a Compaq Smart Array 5300 controller.

When the server boots the kernel loads but will not mount the / file 
system.

In the startup there is the message:
.
.
.
Compaq SMART2 Driver (v 2.4.26)
.
.
.
How do I load the 5300 array controller driver?

Thanks
