What is a BIOS String ID?

The BIOS String ID number is assigned to every motherboard made. It is not always unique but there is usually some good info hidden in the string. The most useful is the portion which identifies the manufacturer of the motherboard. In some rare cases BIOS ID strings are not valid and will not be useful in identifying a motherboard. Some of these cases involve pirated boards, OEM products, or a bad flash routine.
