Programming Interface

Vital Product Data
SurePOS 500-XX3 provides Vital Product Information that includes:
Machine Type/Model
Machine Serial Number
BIOS/Flash ID
System Board ID
MAC Address
VPD is accessed using IBM standard INT 15h interface for finding the VPD data area within the system
post/bios ROM address space. It is also shadowed into the flash ROM at address F000:FFA0
Vital Product Data (VPD) is the information about an IBM system that can be read with software. The data n
includes machine type, machine serial number, BIOS/FLASH ID, system board unique ID, etc. The physical
location of the VPD is in the EEPROM attached to the custom SurePOS 500-XX3 ASIC. This information will
also be shadowed into the flash ROM at address F000:FFA0 as is standard on all IBM PC's. SurePOS 500-
XX3 BIOS will implement the IBM standard INT 15h interface for finding the VPD data area within the System
POST/BIOS ROM.
Much of the VPD information will be written into the DMI strings where the info can be extracted by
applications such as RDM. During the manufacturing process, the machine unique data will be written into the
EEPROM VPD area by the test process. POST will extract the data from the EEPROM for the outside
interfaces to retrieve, such as SMBIOS. Machine unique data can include Model, box serial number, and
planar serial number.
