This chapter describes how to change the primary boot source on a NETBuilder II 
bridge/router with a DPE module.

The NETBuilder software boot files for a DPE module are factory shipped with 
a:/101/boot.29k as the default primary boot source. If you have installed the 
NETBuilder software flash memory card into drive A, and you want to keep the 
default boot source, skip this chapter and refer to Chapter 6. 

If you want to adjust system configuration settings, refer to the SysconF appendix in 
Reference for NETBuilder Family Software for instructions on how to make the 
changes.

The Boot Monitor utility Boot (BT) command allows you to reboot or to override the 
default boot path. The BT command is useful if the boot path has a typing error or 
if you have a malfunctioning drive. If you enter a new boot path, the Primary Boot 
Source parameter is updated to reflect the new path.

To reboot the NETBuilder II bridge/router using the Boot Monitor utility Boot 
command, follow these steps:

1 Reset the system in one of two ways. Either press the two outer buttons on the 

LCD control panel on the front of the NETBuilder chassis, or press the reset 
button on the DPE module.

The console displays the following startup message:

Do you want to enter the boot monitor? (y/n)

For more information about the Boot Monitor utility, refer to the Firmware appendix 
in Reference for NETBuilder Family Software.
