If you enter 2 in the BIOS menu, the BIOS reads the boot program from
the storage medium connected to the USB interface to boot the Linux
system.
This function provides a shortcut to rapid system restoration. You can
backup part of the system installation files into an external storage
medium, such as a USB flash disk. When the system cannot be started
normally due to system kernel file damage, you can use the backup
system files stored in the external storage medium to boot the Linux
system, and then enter the Linux system to locate the problem.
The files that you need to back up include: Initrd, bzImage, and elilo.efi.
For a detailed description of these files, refer to Table 8 on page 30.
If you enter 3 in the BIOS menu, the system installs the Linux system
through the Ethernet port. This option downloads the Linux system files
from a server to the OSN|M for installation. During the installation
process, the OSN|M's hard disk is formatted and partitioned, and
therefore, the original data on the hard disk is lost. Make sure to use the
Ethernet installation function with caution. The OSN|M module supports
address auto-configuration through DHCP.
Install an OSN|M in a Switch 5500G. The controller can enter the BIOS
menu of the OSN|M using several methods to execute the Ethernet
installation of the Linux system. Figure 5 shows the network diagram and
installation process for an Ethernet installation. In this example, the
controller logs into the OSN|M module through the console port install
the Linux system using an Ethernet connection. You can install the Linux
system through the two network cards on the OSN|M module.
