DESCRIPTION: The command BW displays the parameter “” setting.
The parameter “” specifies the waiting time in seconds that the
boot operation is delayed before the image is loaded and started. No
values other than these are supported.
The option “-f” is used to force updating of the CRC value of boot
section of the EEPROM.
Some products do not support values of 0 and 1. Refer to the online
help text for specific information.
With products that support a bootwait time of 0, care should be taken
to ensure that some means are available to access the
NetBootLoader (e.g. via the Abort switch; access to the abort signal;
etc.) before specifying a value of 0. Otherwise it may not be possible
to access the NetBootLoader again during ensuing boot operations.
