RTM VPD EEPROM

The MVME7100ET RTM provides an 8 KB dual address serial EEPROM containing VPD
configuration information specific to the MVME7100ET RTM. Typical information that may
be present in the EEPROM may include: manufacturer, board revision, build version, date
of assembly, options present, and so on. The RTM VPD EEPROM device ID is user
selectable with the recommended value for MVME7100ET as shown in
55. Refer to the EEPROM Datasheet listed in
additional details.

Flash Memory

The MVME7100ET is designed to provide 128MB of soldered-on NOR flash memory. Two
AMD +3.0V devices are configured to operate in 16-bit mode to form a 32-bit flash bank.
This flash bank is also the boot bank and is connected to LBC Chip Select 0 and 1. The
NOR flash is accessed via the MC864xD local bus. The table below shows memory size
and device IDs.
