If you didn't install SILO, you'll have to use your boot disk now.
If you did install SILO, after your computer's normal power-up sequence
has completed, you should see SILO's standard prompt, which is
boot:. At the
boot: prompt, you can do any of the
following things:
Press Enter -- Causes SILO's default boot entry
to be booted.
Enter a Boot Label, followed by Enter -- Causes
SILO to boot the operating system corresponding to the boot
label.
Do Nothing -- After SILO's timeout period, (which, by default, is
five seconds) SILO will automatically boot the default boot entry.
