Determine what/who makes and version of the BIOS for that mobo then take a visit over to http://www.postcodemaster.com.
I'm pretty sure the X38A has an American Megatrends (AMI) BIOS but can only guess at which version.
The Foxconn Smart LED only displays the BIOS POST codes as opposed to the way it was back in the day when you had to purchase a separate pci slotted diagnostic POST code reader to determine the POST and error codes of a particular mobo.
