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
