The invention provides a system and a method of selecting a version of a program code from a series of program codes for a program element associated with a hardware element for a circuit board. The invention identifies a compatible program code for a particular hardware element and downloads the compatible program code. A record is associated with the hardware element to identify its compatible program codes. The program codes are stored in a bundle and are associated with a software code. A program loader, associated with each bundle, checks the compatibilities of the hardware element to both the software code and the selected program code. Another record stores compatibility information of the program codes with hardware element versions and is also associated with the bundle. Code downloads are made first to an inactive memory bank and after the codes are verified, the inactive memory bank is made active.
