Configuring the boot file location
When an administrative user selects the Settings-Boot configuration menu option, the following screen appears.
-Boot Configuration Screen
An administrative user can use the Settings-Boot configuration screen to redefine the location from which the OnBoard appliance boots. By default, the OnBoard appliance boots from an image file that resides on the on-board Flash memory. Booting from the resident software is strongly recommended. Network boots should be reserved only for troubleshooting or upgrading.
The Unit boot from pull-down menu lists the Network option for booting from a TFTP boot server on the network along with one or two boot images that reside on the OnBoard appliance.
A second image appears in the list only if the software has been upgraded.
Local boot options
To understand the local options on the Unit boot from menu, you need to understand how the OnBoard appliance handles software upgrades:
The first time a new software version is downloaded and installed from Cyclades, the new image is stored as Image2 in the Flash memory and the configuration is changed so the OnBoard appliance boots from image 2.
The second time a new software version is downloaded and installed, the latest image is stored as Image 1, and the OnBoard appliance configuration is changed to boot from Image1.
In the Unit boot from pull-down menu, the entry for the current boot image is selected by default.
After a software upgrade, the boot file location choices are:
Image1:image_filename
Image2:image_filename
The word image is followed by the number, followed by a colon (:), followed by the name of the file, including the version number. The menu item has the following format:
image1:zvmppconb.vversion_number
The entry for the first release of the software, which is installed in the image1 area, is:
image1:zvmppconb.v100
After one or more software upgrades have been performed, a second image also appears in the menu, for example:
image1:zvmppconb.v100
image2:zvmppconb.v101
If you want to boot from another image than the one currently selected, you can select that image from the Unit boot from menu.
Network boot options
Network boots are recommended only for troubleshooting or for possible downloads of new software images that can then be stored in the resident removable Flash memory, as described in To upgrade to a boot image from a network boot in U-boot monitor mode:.
