Product Identification
Overview
All current RadiSys SBC’s support product identification. This information is
embedded in the BIOS and can be read by an operating system or application. The
location of the data is fixed for all current products.
BIOS
The starting location for these fields in the BIOS is F000:FF90h (000FFF90h), and it is
identified by the ASCII string "TMI" terminated with a null (0h). All data is stored in
ASCII. A map of the data fields is provided in the following table:
Serial Number
The Serial Number field will contain an ASCII string "S/N," followed by the ASCII
serial number string, terminated with a null. RadiSys serial numbers are eight (8)
characters in length, using numbers and uppercase letters. The operating system or
application must verify the presence of the “S/N” string before attempting to retrieve a
serial number from the location F000:FFB4h.
