1. Each SPD defines the physical attributes of each bank or group of banks. If both banks of a SODIMM are populated they are
the same speed and memory size.
2. This is a dual address serial EEPROM.
3. The device address is user selectable using switches on the RTM. The recommended address setting for the MVME3100 is
$AA.
7.6 User Configuration EEPROM
The MVME3100 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
2-Wire Serial EEPROM Data sheet listed in
additional details.
7.7

VPD EEPROM

The MVME3100 board provides an 8KB dual address serial EEPROM containing vital
product data (VPD) configuration information specific to the MVME3100. 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
