FUNCTION: Set or display the parameters of the boot wait function of the
NetBootLoader
SYNTAX:
bw [<time>|-f]
where:
bw command: bootwait
<time> parameter: numeric string
0, 1, 2, 5, 10, 20, 50
time in seconds
-f option:
force CRC update
DESCRIPTION: The command BW displays the parameter “<time>” setting.
The parameter “<time>” 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.
USAGE: Display setting of “<time>” parameter
