If the configuration was modified but not saved, you are asked to save
the configuration:
System configuration has been modified. Save? [confirm]
If you confirm to save the configuration, you might also receive this
message:
Warning: Attempting to overwrite an NVRAM configuration previously written by a
different version of the system image. Overwrite the previous NVRAM configuration?
[confirm]
Users with open Telnet connections are notified of the system reload,
as:
**System going down for Flash upgrade**
If the TFTP process fails, the copy operation is retried up to thre
times. If the failure happens in the middle of a copy operation so only
part of the file has been written to Flash memory, the retry does not
erase Flash memory unless you specified an erase operation. Th
partly written file is marked as deleted, and a new file is opened with
the same name. If Flash memory runs out of free space in this process,
the copy operation terminates.
After Flash load helper finishes copying (whether or not the copy op-
eration is successful), it automatically attempts an automatic or a man-
ual boot, depending on the value o f bit0 of the configuration registe
boot field:
z Bit 0 = 0 The system attempts a default boot from Flash
memory to load the first bootable file in Flash
memory. This default boot is equivalent to a
manual b flash command at the ROM
monitor prompt.
z Bit 0 = 1 The system attempts to boot based on the boot
configuration commands. If no boot
configuration commands exist, the system
attempts a default boot from Flash memory; that
is, it attempts to load the first bootable file in
Flash memory.
