Configuring for Autoboot
You can configure the AGM to enter ROMMON mode automatically upon a reboot by setting virtual
configuration register bits 3, 2, 1, and 0 to 0.
To configure automatic reboot, perform the following steps:
Step 1 Enter the enable command at the Gateway> prompt to enter privileged mode.
Step 2 Enter the configuration command configuration-register 0x0 at the Gateway# prompt.
Step 3 Enter the reload command at the Gateway# prompt to restart the AGM.
This example shows how to configure for autoboot:
Gateway> enable
Gateway# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Gateway(config)# config-register ?
<0x0-0xFFFF> Config register number
Gateway(config)# config-register 0
Gateway(config)# end
Gateway#
The new configuration register value, 0x0, is effective after the reboot. This means that upon a reboot,
the AGM remains in ROMMON mode and does not boot the operating system. To boot the operating
system, you must do so from the console.
Refer to the boot command in the “General Use Commands” section on page A-3 and the tftpdnld
command in the “Boot and System Image Recovery Commands” section on page A-11.
