Linux Loader (LILO) Menu Options
The bootup process eventually takes you to the Sun Linux loader screen. The Sun Cobalt LX50 server uses the
standard LILO boot loader. You initially have four options:
• linux
• linux-serial
• linux-up
1
• linux-up-serial
1
In all cases, the serial ports on the front and rear panels are operational but their modes change. When you choose any
of the serial boot options (linux-serial or linux-up serial), the serial port (ttyS1) becomes the default console device.
The standard keyboard/mouse/VGA port becomes just a standard tty device. Conversely, when you choose any of the
non-serial options (linux or linux-up), the standard Linux console is the keyboard/mouse/VGA port and the serial port
becomes a standard Linux login terminal.
If you do nothing, the default option (linux) is automatically selected after about five seconds. This option is also
selected if you press Enter before the five seconds is up. You may also manually select one of the options. To do this,
press the Tab key. Pressing Tab brings up the following prompt:
boot:
You may now type any of the options after the prompt, for example:
boot: linux
, or
boot: linux-serial
, or
boot: linux-up
, or
boot: linux-up-serial
After you make your selection, Linux continues to boot.

1. linux-up is Linux uniprocessor, and can be run on a dual-processor server. Linux runs faster if you have a
single CPU and you choose one of the “up” options.
