Power-On Self-Test
The OmniBook 800 BIOS includes a Power-On Self-Test (POST) facility that tests a number of
hardware and firmware items in the unit at each cold-start (BOOT or RESET).
The OmniBook self-test alone should not be used to diagnose a hardware problem. If the selftest results are absolutely clear and repeatable, confirm the results with at least two other nonself-test failure symptoms.
Within POST, there are three kinds of messages:
• Error Messages – These messages appear when there is a failure in hardware,
software, or firmware.
• Informational Messages – These messages provide information to the user but
require no action.
• Beep Codes – This kind of warning sounds when POST errors occur and the screen
is not yet available.
Beep Codes
These multiple beep codes indicate a failure in a simple test of:
• a portion of base memory
• flash BIOS checksum
• a portion of conventional memory
• a portion of extended memory
If the unit fails to boot, ensure that
• all accessories are removed, including:
memory, floppy drive, docking station, modems and other PC Cards, printers,
external displays, pointing devices, and keyboard
• clean AC power is provided (no “chained” battery chargers or auto adapters), and
press reset.
If the unit still fails to boot, it requires service.
Beep codes are used to identify a POST error that occurs when the screen is not available.
Once the screen is operating, diagnostic messages are reported to the screen. There are beep
codes for both fatal and non-fatal system board errors.
Table 2 - POST Beep Codes
Beep Code Description
S-S-S-P-S-S-L-P The DMA page registers are faulty.
S-S-S-P-S-L-S-P The refresh circuitry is faulty
S-S-S-P-S-L-L-P The ROM checksum is incorrect
S-S-S-P-L-S-S-P The CMOS RAM test failed
S-S-S-P-L-S-L-P The DMA controller is faulty

Display Codes
There are a number of Power On Self Test (POST) tests that are performed after the Beep Code
tests. Failure of one or more of these tests will result in a displayed failure code (such as
03044). It is extremely important not to interpret a failure code immediately as a hardware
failure. The failure should be confirmed with a clean boot. A clean boot is defined as pressing
the reset button after removing all accessories (including additional memory, floppy drive,
modems, PC cards, and printers) and providing a reliable power source. Note, make sure the
display is adjusted to be visible.
The following tables lists common PC error messages. Not all of these messages will appear on
every model of the OmniBook 800.

OmniBook Diagnostics
The OmniBook diagnostics program provides an effective tool for diagnosing and isolating a
hardware problem. The diagnostics software is intended for use in concert with additional
troubleshooting methods to accurately determine the cause of trouble. The diagnostics program
is not designed for unassisted end customer use.
Diag is a DOS program developed to test the OmniBook 800 computer and docking station. For
the most part Diag is a stand-alone program, testing components and subsystems independently.
Some tests require “loopback” adapters for complete testing, and some tests require other
hardware (e.g. SCSI devices). Basic knowledge of running software is assumed.
Running the diagnostics program
A “clean boot” is the environment from which to run Diag. For a system that normally boots up
to Windows for Workgroups, press F5 at bootup. For a Windows 95 system, press Shift+F5.
Alternatively, the CONFIG.SYS and AUTOEXEC.BAT files may be modified to exclude drivers
and/or launch Diag if desired. Please note that the SCSI tests do require loading some drivers;
those drivers will be addressed in the context of those tests.
The diagnostic program is located in the c:\omnibook\diag directory and is invoked by typing
diag followed by the Enter key.
Main diagnostic screen
The OmniBook diagnostic program is controlled primarily from a single screen. The top two
thirds of the screen reports the tests selected and test results. The bottom third is used to scroll
test results as the tests run. Thirty tests are listed under the Menu heading. See Figure 4 for a
sample of the main diagnostic screen.
Tests selected for looped running show a test level of 1 to 3 to the left of the test name. When a
test ends, the status of the test and the date and time are reported. As a test runs, ongoing
status can be reported either on the same line as the test, or scrolled into the bottom region.
When looping tests are performed, the bottom line reports when the loops begun and which loop
is currently running. If a test ever fails, a red ‘x’ appears to the left of the test name. The
version of Diag is reported near the bottom of the display, as is the version of the BIOS.
External monitor colors can be checked at a glance with the RED GREEN and BLUE colored
text boxes.

Running selected tests
Tests may be initiated individually, or as a group. Some tests may be run at different levels. In
general, tests that can take a long time to be fully checked have levels that permit testing more
quickly while still providing a reasonable level of testing. An unselected test has a <Space>
before the test name. A test at a quick level has a <1> before the test name. A standard level
test has a <2> before the test name. A long test has a <3> before the test name. Every test has
a standard level. Some tests also have a quick level, and some tests also have a long level.
Some have both quick and long.
8
The name of the currently selected test is always shown inversed.
To help monitor the progress of testing, the LEDs (near the On button) blink about once per
second from green to off. If a test has failed the LEDs blink from red to off. When Diag finishes
testing, the LEDs blink rapidly. If the system locks up for some reason, the LEDs generally stop
blinking.
Alternative methods for running tests
Individual tests may be run by moving the highlight to the desired test and running it. Move the
highlight and run the tests by the following means:
Keyboard – cursor <Up> and <Down> keys to select, <Enter> to run. Also <Space> to specify a
test level, <Backspace> to cancel a test, <Esc> to exit Diag. Many other features and options
are also available from the keyboard.
Contrast/Brightness buttons – <Down> to select (mimics the Down key), <Up> to run (mimics
the Enter key). This is most useful on production units that have no keyboard. For checking
“Newton rings” during display testing, it is necessary to adjust the contrast. To have the contrast
keys operate normally, press both at once. To have them mimic the Down and Enter keys, press
both again.
Mouse – when the -m command line option is specified, use the top or bottom “bumper” to
select, and left button to run. Also use the right button to specify test level (space), right bumper
to cancel a test (Backspace), and left bumper to exit Diag (Esc).
Serial – same keys as with a keyboard, but from a remote system (HP 100LX, etc) connected
into the RS232 port on the OmniBook. The remote computer’s serial port should be configured
for 9600,N,8,1. The communication program Kermit is well suited to communicate with Diag, in
that it sends cursor and function key codes as PC key codes (e.g. <Up> transmits <NULL> then
<;>). Controlling Diag via the serial port permits the same level of control of modes and toggles
as does direct keyboard control. Please note that the serial test cannot be run when the serial
port is used for control (though the serial port gets a decent workout controlling Diag anyway).
Special test hardware requirements
The following tests require the following hardware to operate:
• The Upper/Lower PC Card tests require a Sycard test card and a modified
extender card.
• The IR port test requires another OmniBook 800 running the fast IR test.
• The Serial port test requires an HP RS-232 serial loop back connector.
• The Printer port test requires an HP parallel port loop back connector.
• The SCSI test requires an HP SCSI port loop back connector.
• The SCSI CD ROM test requires a CD ROM device connected by SCSI cable.
• The SCSI Hard disk test requires a Hard disk connected by SCSI cable.
• The Dock slots test are currently unimplemented.
• The Dock keyboard test requires a docking station and an external keyboard.
• The Dock PS2 mouse test requires a docking station and a PS2 mouse.
• The Dock EEPROM test requires a docking station.

Loop Back Connectors
In order to run the RS232 serial port, parallel port, and SCSI port self-test, a loop back connector
is needed. The loop back may be placed on either the OmniBook port or at the end of the
corresponding cable. This feature is also helpful in diagnosing a defective serial, parallel, or
SCSI cable.
Loop back connectors may be purchased or can easily be constructed. The following illustrations
identify the correct pin-out configurations for the serial, parallel, and scsi loop back connectors.
Figure 5 - Serial Loop Back Connector

Figure 6 - Parallel Loop Back Connector
PCMCIA Type III extender card
The PCMCIA test that makes use of SyCard Technology’s SyCard also requires an extender
card modified with two jumpers or with solder bridges. In order for the Sycard to be detected,
CD1- and GND must be shorted together, and GND with CD2- must also be shorted together.
These are both pairs of endmost pins on the extender. Once these jumpers or solder bridges are
added, the SyCard will successfully be detected and the SyCard tests can be performed. See
Figure 8.
