I have an Intell entry server board SE7221BA1-E  WITH 4gb of ram installed. the bios shows it, when I install windows server 2008 Enterprise it loads up just fine and the OS shows 4 full gigs or ram.
When I try to install SBS 2008 it states that there is not enough ram and stops the install. Any ideas as to why this is happening some thing in the bios I missed?

    I presume you are trying to install 64 bit Edition of SBS 2008, 4gb is the minimum amount of RAM require for 64bit. I have provided a link below that might help to explain this.

    Have you tried increasing the amount of RAM?

    In the real world, 4 gigs is not adequate for SBS. Upgrading to 8 will both resolve your problem and provide you with a reasonable (but not great) SBS platform.

    As far as the actual cause, Intel boards in particular are notorious for "borrowing" memory for their own use (on-board RAID, graphics caching, etc) and so what is left for the OS is actually slightly less than 4 gigs; thus the install fails. Standalone 2008 servers will install in less than 4, but the SBS installer puts a hard bottom limit at 4, so the install fails. Upgrading RAM is the only option.

    I have minimum amount or ram but as to what the actual reason may be increasing the ram is a standard technique and we all that will work fine.
