Power-on Diagnostic and Boot Errors
When the power-on diagnostic tests detect an error, the
computer displays a message on the screen (as described
below) and the speaker beeps twice. If the error occurs before
the computer initializes the video display, the speaker sounds
a series of beeps.
Each error is identified by a message number and a
countdown number which the computer uses as it executes
the test associated with the error.
The table below lists the power-on diagnostic and boot error
messages, and some basic solutions to the problems.

Error Tone Codes
If power-on diagnostic tests detect an error but cannot display
an error message, the computer sounds an error tone code.
The tone code is a distinct pattern of beeps that identifies the
error, such as one beep-two beeps-one beep. If the error is
serious (fatal) the computer locks up, but if the error is not
serious (non-fatal) you can continue using your computer.
The tables below list the fatal and non-fatal error codes.

Hard Disk Drive Types
The following table lists the types of hard disk drives you can
use in the computer. Check this table and the documentation
supplied with your hard disk to find the correct number for
the type of hard disk drive(s) installed in your computer. You
need to enter this number when you set the hard disk drive
configuration in the SETUP program.

Installation/Support Tips
System Power Requirements
The power cord must be rated for at least 125% of the current
rating of the AC voltage system and must be less than 4.5
meters (14.76 feet) long to comply with the system’s safety
requirements. Do not use or attempt to modify the supplied
AC power cord if it is not the type required for use in your
region.
To avoid permanent damage to the computer, be sure the
voltage selector switch is set to the correct input line voltage
before you turn on the power. The computer is shipped with
the voltage selector switch set to 115 VAC, which is
appropriate for line source voltages between 100 and 120
VAC. If the line source voltage in your location is between
200 and 240 VAC, make sure you set the switch to 230 VAC.
Keyboard and Monitor
Even if you intend to use this system as a network file server,
you need to connect a monitor and a keyboard to complete
the installation. You may remove them once the installation is
complete.
Mouse and Keyboard
When connecting the mouse and keyboard, be careful to plug
them into the proper ports. Although they are physically
identical, they are not interchangeable, and damage may
occur to the ports or the main system board.
SETUP
Use the SETUP program in your system’s BIOS ROM to
configure your computer if you installed only ISA option
cards that did not come with CGF files or you do not have a
diskette drive or you have disabled the diskette drive.
Run the EISA Configuration utility on the Reference diskette
to configure your system if you have installed EISA option
cards or you have installed an ISA option card that came
with a configuration file.

Option Cards
The order in which you install option cards depends on the
type of cards you have. If you install only ISA option cards
that do not have their own configuration files, install them
before you connect your peripheral devices. Follow the
instructions in your ISA card manual to set the card’s
switches or jumpers for your system.
Also install any EISA cards you plan to use before you
connect peripheral devices so your EISA Configuration utility
can automatically detect the cards and configure them
correctly.
If you install ISA cards that came with their own
configuration (CFG) files, install them after you have
connected the necessary peripheral devices and run the
computer’s EISA Configuration utility. This allows you to
add the CFG file information to your configuration so the
program can give you the card’s correct jumper and switch
settings. Then you can set the switches and jumpers and
install the card. See the documentation that came with your
card(s) for more information.
