NVMM Utility

With the NVMM utility, you can:

move modules from OS-9 to non-volatile module memory

list all modules in the non-volatile module memory

enable deletion of modules in the non-volatile module memory

delete modules from the non-volatile module memory

Syntax for the NVMM utility is:

NVMM -M [module] Moves module into

non-volatile module memory

NVMM -L Lists all modules in

non-volatile module memory

NVMM -D Enables deletion of modules in

non-volatile module memory

Important: When you move modules to the non-volatile module memory,

they are not included in the OS-9 Module Directory until the next

system boot.

When

delete enable is set by the NVMM utility, the next system boot

automatically invokes NVMM in a menu mode. From the menu, you can

list and delete modules in the non-volatile module memory.

To protect modules that are used by other processes, you can delete the

modules from non-volatile module memory only during the next

system boot.

See Figure 3.16 through Figure 3.18 for an example session of NVMM.
