Vital Product Data (VPD) Introduction

The data listed in the following tables are for general reference information. The VPD
identifies board information that may be useful during board initialization, configuration and
verification. This section includes information on how to perform various tasks to read,
modify and correct Vital Product Data, as well as specific format and content information
for this product. Information that is contained in the VPD includes:
 Marketing Product Number (MVME4100-0171, MVME4100-0173)
 Factory Assembly Number (0106855E03x, 0106855E04x)
 Serial number of the specific MVME4100
 Processor family number (xxx)
 Hardware clock frequencies (internal, external, fixed, PCI bus)
 Component configuration information (connectors, Ethernet, addresses, flash
bank ID, L2 cache ID)
 Security information (VPD type, version and revision data, 32-bit CRC protection)
