We received a dell poweredge 2850 server as a donation in my organization.  I want to use it for a centos 6 installation, but 2 things are happening that have me stumped:

1- The raid controller is not allowing the centos installtion to see the hard drives.  I configured the array as Raid 5, intialized the logical drive, but still no luck.  

2- BIOS tells me there 2GB of ram, but the machine is only allowing 256M to be used.  I have no idea why.

For issue 1, I'd love to be able to get rid of the raid controller and simply use the on-board scsi controllers, if that is possible.  I really don't need redundancy on this machine.

For issue 2, Centos is reporting that there is not enough Ram to install, even though BIOS says there's 2 GB.

Any help is greatly appreciated

Check your BIOS settings - you probably have "OS Install mode" set to ON. This will limit memory to 256M.

You can also turn RAID mode off in BIOS, and get simple scsi controller.
