Changing the Boot Image in U-Boot Monitor Mode
You can access U-Boot monitor mode in one of the following two ways:
• During boot, when the “Hit any key to stop autoboot” prompt appears,
pressing any key before the timer expires brings the KVM to monitor
mode.
• If boot fails, the KVM automatically enters monitor mode.
The U-Boot
hw_boot
command boots from either the first or second image
according to the value of the “currentimage” environment variable, which can
be either 1 or 2. You can use the following procedures to specify another
image.
Image names:
image1:zvmppcons.v100
image2:zvmppcons.v102
Current image (image(1) or image(2)) [1] :
Current image (image(1) or image(2)) [1] : 2
