[CentOS] After install centos does not find hardrives (SATA)

Hi we installed centos on a Intel server board with LSI rad (no raid configured 
for the lsi).  in Centos it sees both drives so we software raid them and the 
installation goes well and finishes properly.  The problem is when the server 
reboots it can no longer see the hard drives and no just boots to a low level 
diagnostic shell.  Any ideas?



Thanks
