ENV Parameter and Options
ENV asks the following series of questions to set up the VMEbus interface for the MVME162

series modules. You should have a working knowledge of the VMEchip2 as given in the
MVME1X2P2 VME Embedded Controller Programmer's Reference Guide in order to perform
this configuration. Also included in this series are questions for setting ROM and Flash access
time.

Slave Enable #1 [Y/N]
Slave Starting Address #1
Slave Ending Address #1
Slave Address Translation

Default is 0.
This register defines which bits of the address
