Unable to mount logical drive after driver loads successfully

Hello 

We are in desperate need of your help.

We have SBS2011 server (2008r2 + Exchange 2010).  The server has a Raid5 using onboard controller. Server is a Dell T110 II  Service Tag: FD4XRR1. 

This is not my first time preforming a restore but fur sure is the most frustrating. What is happening is that onfter we boot into the PE Recovery from the recovery disk. The logical drive are not showing. I got a controller driver form Dell (there are only 2 X86 & X64). I used the X86 driver which says that it loaded successfully however the logical drives don't get mounted. What am i missing? Is there some sort of CLI command i need to run to get the drives to mount?

Any and all help is appreciated...

Thank you
