OmniBook Self-Test
(Not all units have
this self test
built-in)
First POST: BEEP
CODES
Cannot remote print to DJ550C w/ new ColorSmart Drivers
Use DeskJet 500 drivers or connect directly.
Cannot remote print w/ DJ Plus ColorSmart driver loaded

Status Panel is "permanently" missing. Running OBSTATUS results in "already
running" message. Status panel has been turned off and then removed from the
F1-12 hot key group.
Add OBSTATUS.EXE back into the f1-f12 group, exit and restart windows,
invoke the appropriate fn key to turn on the status panel.
The complete self-test procedure is documented in the OmniBook 600 Operating
Guide.
A note about interpreting self-test results.
Self-test alone should not be used to diagnose a hardware problem. If
the self-test results are absolutely clear and repeatable, confirm the
results with at least two other non-self-test failure symptoms.
The OmniBook 600 BIOS includes a POST facility that tests a number of hardware
and firmware items in the unit at each cold-start (BOOT or RESET).
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:
all accessories are removed, including memory cards, external floppy,
port expander, modems, PCMCIA cards, LAN cards, printers, VGA-out
cables, external pointing devices, 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
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 nonfatal system board errors.
