Here is a link to an installation utility.  The Dell PowerEdge SC Server Installation CD contains the tools needed to configure the SC system and install the operating system. This CD also delivers the latest firmware, diagnostics, and Dell-optimized drivers. www.dell.com/.../DriverFileFormats You would create the disk from the download then boot to the disk and go thru the prompts choosing the options that you need then you would insert the OS disk when prompted to complete the installation. The disk was configured in 2006 so there may be some more current individual drivers and firmware available, but this will get you going. Here is a link to the main driver update page for the SC 1420. www.dell.com/.../04 Also you may want to turn off the OS install mode in the BIOS depending on how big you installation files are.  You are limited to the 256 mb with it enabled. Hope you find this helpful.
