CHANGING THE BOOT SOURCE

	This chapter describes how to change the primary boot source on a bridge/router or
	tunnel switch.
	The Enterprise OS software boot ﬁles for the main processor module are factory
	shipped with a:/primary/boot.29k as the default primary boot source for NETBuilder
	bridge/routers. If you have installed the Enterprise OS software ﬂash memory card
	into drive A, and you want to keep the default boot source, go to Chapter 4.
	If you want to adjust system conﬁguration settings, see the SysconF appendix in
	Reference for Enterprise OS Software for instructions.
	3Com recommends that you initially use the ReBoot command to boot the
	bridge/router or tunnel switch. If this command fails, use the BT command.

Using the Boot	The Boot Monitor utility Boot (BT) command allows you to reboot or to override the
Command	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 (or tunnel switch) using the Boot Monitor
	utility Boot command, follow these steps:

1Reset 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 main processor module.
