User Configuration EEPROM

The board provides two 64KB dual address serial EEPROMs for a total of 128KB user
configuration storage. These EEPROMs are hardwired to have device IDs as shown in
Table 4-4, and each device ID will not be used for any other function. Refer to the EEPROM
Data sheet listed in
4.7

VPD EEPROM

The MVME7100 board provides an 8 KB dual address serial EEPROM containing Vital
Product Data (VPD) configuration information specific to the MVME7100. Typical
information that may be present in the EEPROM may include: manufacturer, board
revision, build version, date of assembly, memory present, options present, L2 cache
information, etc. The VPD EEPROM is hardwired to have a device ID as shown in
MVME7100 Single Board Computer Programmer's Reference (6806800E82C)
