NEC POWERMATE PRO150 Manual page 29

After booting the system, the POST may find the following possibilities.
What happens
If the settings in CMOS RAM match the hardware
configuration, and if the POST does not find any
errors, the power-on testing continues.
If the POST finds a fatal error (an error that
prevents the system from continuing the boot
process), it generates a series of beeps. A specific
number of beeps indicates a certain error
message.
If the POST finds a non-fatal error (an error that
doesn't stop the boot process from continuing), the
system displays a message in the following format:
Error Message Line 1
Error Message Line 2
Press <F1> for Setup,
<Esc> to Boot
If you need to reconfigure the system setup, start
the Setup program.
If you need to begin again, reboot the system.

What to do
No action needed.
Record the number of beeps.
See Chapter 6 for a description
of the system beep codes and
troubleshooting procedures.
Locate the error message in
Chapter 6, and take action as
indicated under the explanation
for the error message. If
needed, run the Setup
program.
Reboot the system and press
<F1> as soon as you see the
message "Press <F1> Key if
you want to run SETUP." You
have about five seconds to
press <F1> to enter Setup
before the boot process
continues.
Press <Ctrl + Alt + Del>.
