During default boot, LiveCD image is copied to and run from RAM.
   * A minimum of 1GB RAM for this option is recommended. 
   * For optimal use/functionality at least 4GB RAM is recommended.
   * After boot is complete the media is ejected and optical-drive is
        available for use.
   * This option has increased boot time over other boot options but has
        greatly increased live environment performance.
   * If booting with less than 4GB of RAM, potential exists for filling
        the read-write overlay (device-mapper snapshot) and preventing
        most system operations. If encountered, reboot the LiveCD.

   
If less than 1GB of RAM is available use boot option: Boot (run from CD) 
   * The media is required to remain in optical-drive while using the
        LiveCD environment when booted to this option.
   * This option has a faster boot time but a decreased live environment
        performance due to continued reading of the media.


The LiveCD environment logs in automatically to a graphical user 
interface desktop. To use actual username of 'root' (for use with ssh or 
OMSA, for example), the password is: dell.


Root's default password may be changed by running 'passwd' from CLI or 
graphically from System -> Administration -> Root Password


Root login is enabled for ssh.


There is no firewall configured and selinux is disabled.


OMSA can be launched by the icon on the desktop or by using 
https://localhost:1311. To login use the username: root and the 
password: dell. 
  * May need to follow self-signed cert exception process
  * May need to disable Firefox Offline Mode


NetworkManager configures networking via DHCP when booted to any of the 
graphical environments (including the default boot option). If you need 
to set static IP(s), stop NetworkManager and configure networking using 
CLI or graphically from  System -> Administration -> Network.


NetworkManager does not run when booting runlevel 3, use CLI to 
configure networking manually.


Connection via VNC to display :0 is available when booted to any of the 
graphical environments (including the default boot option).


The folder /tmp/data is shared via httpd, vsftpd, samba, and nfs. It is 
also accessible using scp and sftp (as is the entire LiveCD filesystem).


Dell On-Line Diagnostics may be executed by running 
'/opt/dell/onlinediags/startDiags.sh' from a terminal within X.


There is a launcher for DSET on the desktop that will create a DSET 
report. This report is saved to /tmp/data which is accessible via ftp, 
http, nfs, and smb. 


Partitions and LogicalVolume filesystems (ntfs, vfat, ext2, ext3) on the
local disks are automatically mounted read-only during boot. They will 
need to be manually mounted read-write if write operations to local-disk 
filesystem are required (such as editing config files on the local-drive 
filesystems).  Pass parameter 'nolocalfs' at boot to suppress this.


Local-disk swap is activated on boot. Pass parameter 'noswap' to suppress.


Dell system updates can be run from this environemnt. SUU should work as 
well as individual DUP(s) from support.dell.com.


Yum may be used to install additional packages from public CentOS 
repositories. 


Net-snmp is installed and available by default. This can be used to 
allow ITA to discover the server while it is booted to the LiveCD 
environment. The snmpd.conf file will need to be configured by setting 
the appropriate IP and community name in two locations. 


Many common CentOS5 commands and utilities are available.
