You can save your changes by selecting Save. Saving the changes updates files

VXILA.CFG

,

VXIBUS.CFG

,

VXIDEV.CFG

, and

DVXI.CFG

. These files are used by

VXIINIT.EXE

to

update the soft-configured settings, including board interrupts, shared RAM size, VXI register
contents, and bus interface. You can exit the program at any time without saving any changes
you have made by selecting Abort.
