These 7210 SAS platforms support the following options to retrieve the boot.tim and TiMOS/SROS images (both.tim) required to boot the system:
internal flash (cf1:\)
external flash (cf2:\)
external USB flash (uf1:\)
network (with auto-init)
This option is supported only on the 7210 SAS-T.
network (without auto-init)
Because multiple storage locations are available for the bootstrap image boot.tim file on the 7210 SAS-T, 7210 SAS-R6, and 7210 SAS-R12, these platforms do not support the golden bootstrap image.
During bootup, the bootrom searches for the boot.tim in the following locations in the specified order and uses the image obtained from the first location where boot.tim is found to load the bootstrap image:
cf1:\ (internal USB)
cf2:\ (external flash)
uf1:\ (external USB)
If the boot.tim is not found in any of these locations, the boot procedure fails. If the boot.tim image is found, the system searches for bof.cfg (the boot options file) on the same storage device in the root directory. For example, if boot.tim is found on cf2:\, the system also looks for bof.cfg in cf2:\bof.cfg.
If bof.cfg is found, the system uses the BOF to locate the TiMOS software (both.tim file), configuration file, and other boot parameters, and processes them to boot the system. If the BOF is not found, the system attempts to retrieve the BOF from the network using the auto-init mode and create a new BOF as part of the auto-init process.
In some cases, the BOF may specify different storage device locations for the TiMOS image (both.tim) and the configuration file. For example, the bootstrap image boot.tim file may be located on cf1:\, but both.tim and the configuration file may not be located on this device. You can use the show>system>information command to identify the location of the BOF and the boot.tim image used to boot the system.
The following is a sample output of system information for the 7210 SAS-T.

See System boot option modes for more information about the auto-init and manual boot option modes, and how the system processes these options and loads the boot loader (boot.tim), the TiMOS image (both.tim), and the configuration file to make the system operational and ready for use.
