To everyone who has commented, thank you.
Just to be clear, this is a custom modified computer that uses an intentionally modified and limited BIOS by the OEM. It is not a widely distributed (i.e., commercially available / consumer focused) model. It is directed at industrial manufacturing and limiting the options available enhances the manufacturers ability to support this unit in production environments.
This was not included in the original posting because I thought it would cloud the issue at hand.
Again, thank you all for your replies.
