Re-enabling Normal Operation

setenv diag-switch? false
setenv output-device display
setenv input-device keyboard
setenv auto-boot? true
To make the changes take effect, press
Pause-O
to power down and
then press the power-on button to power on again.
Software Problems
The operating system controls the peripherals and is, therefore, a critical
component in enabling the SPARCbook to operate correctly. For
example, a minor error in a network configuration file can completely
prevent the network interface from operating.
This section provides some information on common software problems
and gives brief advice about possible remedies in each case. By its very
nature it cannot be complete and situations may arise where you need
the help of an experienced system administrator or Tadpole Customer
Support. See “Getting Further Help” on page 16-2.
Stopping processes
To stop the processes that use keyboard input, press the interrupt
character
Ctrl-C
. This normally causes a program to exit. However, not
all programs recognize or act on the interrupt in which case you need to
kill the process in order to halt it, as described in the next section.
