Trek-725 User Manual 34
Option (5) Boot Delay
Choosing this option allows the configuration of the number of seconds
that the boot loader waits for user input before continuing with the image
download or launch. The following prompt is displayed:
Enter maximum number of seconds to delay [1-255]:
Option (6) DHCP
Choose this option to enable or disable DHCP. When DHCP is enabled
the static IP address is not used. When DHCP is disabled, the static IP
address is used.
Option (7) Program RAM Image into Flash
Choosing this option instructs the boot loader to store a normal NK.BIN
RAM image into flash memory. This image may be launched via option
(L). When launched, the boot loader reads the entire image out of flash
and stores it into the appropriate location within SDRAM. It then exe-
cutes this image from SDRAM exactly the same way it would have had it
downloaded the image into RAM and never stored it into flash. Because
the image runs completely out of SDRAM, system performance is
improved due to the faster access speeds associated with this memory
type.
Option (8) Check Image Signature(s)
Choosing this option will check the signature of the downloaded binary
image. Note that the released image is not signed so this is expected to
fail.
Option (A) Automatic Startup Behavior
Choose this option cycles the default boot behavior from downloading a
new image at startup to launching the existing flash resident image. The
existing flash image is the flash image that is programmed when an
NK.BIN image is programmed into flash.
Option (B) Boot Device Order
This option is not used in TREK-725. The boot device is always NPE0.
Option (C) Ethernet Debugging
This option is not used in TREK-725. It must be set to DISABLE.
Option (D) Download Image Now
Choose this option to break out of the menu, save any applicable changes
that were made and then continue with the image download process.
