6.5 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.
6.5.1 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
firmware allows certain VME settings to be changed in order for the user to customize 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 Tsi148 User
Manual, listed in
Appendix B, Related Documentation .

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.
