Downgrading ppciboot/linuxito 4-41
1. Save your configuration to a network tftp server (see
"Saving the Configuration to the Network" earlier in this
chapter.
2. Put the appropriate matching ppciboot/linuxito on your tftp
server as filenames ppciboot.img and linuxito.img.

This reboots the LX.

password. The ppciboot Main Menu appears.

bootp, rarp, or user config) by entering the necessary

6. Type "s" to save the configuration.
7. Type "r" to return to the main menu screen and make sure
the Boot from network field (1) is set to "Network,
