Firmware Settings

The following sections provide additional information pertaining to the MVME7100ET VME
bus interface settings as configured by MOTLoad. A few VME settings are controlled by
hardware jumpers while the majority of the VME settings are managed by the firmware
command utility vmeCfg.
VME settings in MOTLoad are preserved through the use of Global Environment
Variables (GEVs). Configuration GEVs are executed only at power-on reset.
Therefore, if VME configuration changes are implemented through vmeCfg and
board reset must be effected for the changes to be implemented in MOTLoad.

Default VME Settings

As shipped from the factory, the MVME7100ET has the following VME configuration
programmed via Global Environment Variables (GEVs) for the Tsi148 VME controller. The

environment. The following is a description of the default VME settings that are changeable
by the user. For more information, refer to the MOTLoad User's Manual and Tundra's
