Joe,
The system you linked to is a DCS CS24-TY. The DCS (Dell Custom Solutions) systems are custom builds to a different spec than the standardized systems. The C1100 does have some connection with the DCS CS24-TY, but are completely different systems from a firmware and update standpoint. The C1100 BIOS update can actually damage the DCS CS24-TY's board. That being said the updates on support.dell.com are for standardized systems. To find an update, if there is one out for it you would need to contact DFS Support at 800-891-8595.
