13Also some key caps have characters that cannot be displayed with the text
characters available.  Therefore, when running the keyboard test on a foreign
keyboard, the POSITION of the key within the keyboard should match the
POSITION of the key shown on the display, not necessarily the character printed on
the key (although in nearly all cases, it does match).  When -x is specified, the extra
key appears as >< before the SP key.-1Mark all tests for quickest test available.  This has the same effect as...

mouse test.  The defaults limits are 200 to 400.Alt+E + Alt+MSet mouse bumper failure threshold.  The default number of mickeys for this is
1000.  The number reflects how much bumper compression is permitted before
a bumper is rejected.Alt+E + Atl+SSet sine mouse test threshold.  For mice that exhibit sine wave patterns along
the left side of the screen, use this key to specify how much will be tolerated.

17Alt+CSet Contrast 0-255.  Systems with a DSTN display can specify a display contrast
from 0 to 255.  This exceeds the normal range permitted with the contrast buttons
and can result in a blank display.  Repeat the command with a less extreme value
to restore the display.Alt+DSet device type that should be found in the dock port.  Once specified, the
“Docked device” test will only pass if the correct device is found.  The OmniBook
dock port can accept either a SCSI cable for connection to a tower, or a...

18operation of all tests depend on the presence or absence of XMS or EMS drivers.  In general, if
there is no XMS and no EMS driver, then memory will be accessed directly in pseudo-32-bit
mode (i.e.  with 4 GB selectors but from real code), if there is an XMS/EMS driver, the XMS
driver will be used to access memory.  The recommended environment is real mode without
XMS or EMS drivers (i.e. a clean boot).
Pattern testing and address testing are similar.  The pattern test sequentially writes the 18...

19Figure 9 - Sycard Test Results
The OmniBook model F1360 supports zoom video and Cardbus.  If a Sycard model 450
PCMCIA socket tester is found (in the upper slot only), a zoom video test will be run on that slot.
Lower PC Card
Level: 2.  This test operates like the upper PC card test, but for the lower slot.  Manual insertion
is generally required to test both slots.
Timers
Level: 2.  This test checks that all three system timers are counting correctly, and that the control
lines of programmable clock 2...

20received is echoed back to the host.  The IR port is first tested in slow mode by sending /
receiving data packets at 115K baud. If this passes, then data packets are transmitted in high
speed at 1 megabit then 4 megabit.  These IR transmission tests are repeated 3 times.
Serial port
Levels: 1,2.  The level 1 test checks the internal operation of the serial port and does not require
a loopback.  The internal registers are pattern tested to ensure the port can interrupt the system.
Then an internal...

21Keyboard
Levels: 1,2.  The level 1 keyboard test checks that the keyboard responds appropriately to
commands sent from the CPU.  The level 2 keyboard test also checks that each key functions
properly.  The level 2 test passes when each key has been pressed or aborts if the  or
 key is pressed three times in a row.  The special keys that do not generate key codes (
, , and  ) are tested after the other keys have been tested.
Press the key when prompted to complete the keyboard test.  The display shown...

press a key again to exit the test.  This will end the text mode mouse test.
IMPORTANT NOTE ON THE USE OF BOTH BUTTONS:  any time both buttons are pressed
down, a release of just one button will NOT be recognized.  BOTH buttons must be released to
clear the button status.
If verbose mode is enabled with Ctrl+V, then all switch changes are reported in a scrolling
window along the left edge.  The following codes...
