Graphic mode mouse sine test
This mouse test is used to measure the maximum “sine effect” of the mouse.  To select this test,
press  once before running the mouse test.  When run, the screen switches to an
800x600 graphic mode, a blue box is drawn scaled to the expected distance the mouse can
move, and a prompt appears along top line as follows:      -10           +42                                    TOP      -3 OUT     -1034                                     UP     +14           -46                                     +22           -95 BOT                           -30     TOP +1635                                  LB  RB      -3           +54                                             +21         -1688 BOT                           -65     TOP +1640                                      +5           +48                                              +17          -658 BOT                     IN LEFT         RIGHT OUT    -235            -4                                              +15           +93                                             +195          -688 BOT                                          +97           +25                                             -177     TOP +1639                                     +23           +48                                   DOWN    +411         -1145 BOT                              BOTTOM    +105           -33     +70     TOP +1667                  Internal Mouse - I/O test      +8           +21                  Move the mouse in all four directions.    +227     TOP   -44                  Press both mouse buttons.     +34           +47                  Press the mouse against each edge stop    +169          -639 BOT              Park the mouse when finished.     +42           -25                  Press any key to exit the mouse test.     -44     TOP +1655     -15           +30    +129 OUT      -730      +9           -24   -2815          -861     LEFT     -76           +22                   20   43   43   43   43   +2802 OUT      +145                   19   12   12   12   12    +132          +166                   17    2    2    2    2     -89 OUT       -50                   16   21   21   21   21     +89            +8                   15   12   12   12   12IN -2965          -223                   14   48   27   47   66      +0           -25                   13   69   40   67   93IN    +0           -16                   12   91    0   45   91     -26           -19                   11   21   21   56   81    +879           +39          RIGHT    10   40   40   40   40      +0            +2                    9   41    1   23   71      +0            +0     LEFT           8   93    1   32   93      +0            +0                    7   40    1   31   53      +0            -1          RIGHT     6   12   12   39   84      +0            +1                    5  507  507  507  507      -1            -1                  TIC  CUR  MIN  AVG  MAX 
						

							24Figure 12 - Mouse Test Screen (graphics mode)
As the prompt indicates, to run this test, you must move the mouse to the corner where the white
box is displayed (initially the top right corner).  When you activate BOTH bumpers at that corner,
the white box moves counterclockwise to the next corner.  KEEP THE MOUSE PRESSED
AGAINST THE TOP BUMPER AS YOU MOVE.  In order to ensure the mouse is moving in a
straight line, the mouse must stay in contact with the bumper.  As you move the mouse, the path
of the mouse is drawn on the display.  Move the mouse all the way to the top left corner and
press the mouse into the top left corner (careful not to press so hard that you “park” the mouse).
Once you engage BOTH bumpers at the new corner, the white box will advance to the next
corner.  It is important to observe the white box to ensure that you have indeed engaged BOTH
bumpers at the corner you are moving to.  To help you know when a bumper is engaged, a white
bar is displayed along an edge whenever the bumper for that edge is engaged.  Continue to
move the mouse counterclockwise until you reach the lower right corner.  At this point you should
see a red trail of dots indicating the path the mouse has traveled.  This completes the first test
cycle.  Now continue moving the mouse to the top right corner again to begin the second (and
last) test cycle.  Blue is used during the second cycle to distinguish the first cycle from the
second.  SUCCESSFUL OPERATION OF THIS TEST REQUIRES THAT THE MOUSE BE
MOVED TO THE CORNER WHERE THE WHITE BOX APPEARS; WHEN YOU GET TO THE
CORNER, GENTLY PRESS THE MOUSE INTO THE CORNER UNTIL BOTH BUMPERS ARE
ENGAGED.  WHEN THIS IS DONE, THE WHITE BLOCK WILL ADVANCE TO THE NEXT
CORNER.
As the mouse moves, the status of the mouse is reported along the top line, for example:
Cycle=1/2, X=1050,Y=1, Err^=3 Errv=0  TopEdgeErr=0 BotEdgeErr=0
Cycleindicates which test cycle is in progress.Xindicates the X position (0 is the left edge).Yindicates the Y position (0 is the top edge).Err^indicates the current maximum error drift upward.Errvindicates the current maximum error drift downward.TopEdgeErrindicates the maximum total sine error along the top edge.FOLLOW THE  FROM CORNER TO CORNER. PRESS MOUSE INTO EDGE BUMPERS AS YOU MOVE.     
						

							25BotEdgeErrindicates the maximum total sine error along the bottom edge.When the two cycles are complete, the maximum of the top and bottom errors is compared
against a test threshold.  If above, the test fails, else the test passes.  The default threshold is 10
pixels.  The threshold can be set with the command key .
NOTE: for test stations that have no “bumpers” to indicate edge detection, the operator must
move the mouse to the top right corner, then press either mouse button to indicate the mouse is
in position.  Proceed counterclockwise as normally, keeping the mouse pressed against the edge
of the test fixture.
Text mouse and graphic sine mouse tests selected.
This test simply combines the first and second mouse tests.  Note that the sine test is not
repeated after the PS-2 text mode mouse test.
Graphic draw screen mouse test selected.
This test lets the operator draw on the display to visually inspect for the degree of mouse sine.
Hold the left button to draw in blue, the right to draw in yellow, and both to draw in green.  The
cursor is a red heart shape. The prompt for the test is as follows:
LEFT=BLUE RIGHT=YELLOW BOTH=GREEN. ENTER OR ^ TO PASS, OTHERS FAIL
The raw mouse coordinate position is also reported to the right of the prompt.  Additionally, as
bumper or button events occur, these events are reported on the right end of the top line as
rightward scrolling text that changes from white to red as new events occur.  The characters L,
R, and four arrows pointing to each side indicate the event that has just occurred.
The mouse can be toggled between manual and automatic calibration.  The current selection is
indicated by the word MANU or AUTO in the top left corner.  Change the selection by pressing
the mouse into the top left corner.  When manual calibration is selected, move the mouse to
each edge to calibrate the mouse (permit movement to all screen positions).  When automatic
calibration is selected, move the mouse to an edge and hold it there to calibrate the mouse.
After drawing as desired, press  or the contrast up button (^) to indicate pass, any other
to indicate failure.
This test is can also be used for determining button signal strength at various positions on the
screen.  Hold both buttons and draw to all regions of the display.  Green dots only should appear
on the screen as you draw.  Blue or yellow (or nothing at all) indicate button signal strength loss.
Mouse Calibration testing.  To begin measuring lost calibration due to speed in the vertical
[horizontal] direction, move the mouse against the upper [left] edge and press the left mouse
button.  The top line will prompt the operator to move the mouse in the selected direction.  With
each sweep of the mouse the speed will be displayed within the expected speed range (e.g. a
speed of 400 when the low limit is 300 and the high limit is 500 shows as:  300
						

							26Audio
Level: 2.  This test checks the SoundBlaster compatible audio sound system.  The DSP chip,
DMA Channel, and Interrupt Lines are checked for proper operation.  An audible sound test
completes the test; a bong sound alternating between left and right speakers should be heard.
Display
Levels: 1,2,3.  This test checks multiple display subsystems.  When manual testing is done, the
display pixels are first tested with 7 operator-paced test patterns: one each for white, red, green,
blue, and black; then a vertical stripe pattern followed by a random display pattern.  Press Enter
or Contrast Up to pass, Esc or Contrast Down to fail, until the automated test begins.  The
automated display test first tests video memory by flipping to all video modes supported while
writing / reading the video buffer with the 18 test patterns.  Lastly, the VGA controller registers
and VGA color-DAC registers are tested for proper operation.
Docked device
Levels: 1,2.  The dock port can be left unconnected, connected to a SCSI tower via SCSI cable
or connected to a dock.  The level 1 test simply reports what is connected.  If a specific device
has been specified with the  command, then the test will report an error if anything other
than that which what was specified is found.  If a dock is connected and level 2 is selected, then
the dock LED’s and latch are tested by blinking the selected LED and locking/unlocking.
Respond ‘Y’ or ‘N’ as prompted to pass or fail each test depending on the observed performance.
SCSI CD ROM
Levels: 1,2.  This test checks a SCSI CD ROM using the MSCDEX API.  Instead of a clean boot,
drivers must be loaded in CONFIG.SYS and AUTOEXEC.BAT.  The following are a minimum
driver set to enable SCSI CD’s as well as SCSI hard disks.  Note: the directories listed below are
the default.
CONFIG.SYS:
devicehigh=c:\scsi\aspi8xx.sys /v
devicehigh=c:\scsi\symcd.sys /d:aspicd0
devicehigh=c:\scsi\symdisk.sys
AUTOEXEC.BAT:
c:\windows\command\mscdex /d:aspicd0 /m:12 /l:H
The level 1 test does a quick random scan of the CD.  The level 2 test does a linear scan,
random scan, and a funnel scan of the CD to test for proper operation.
SCSI Hard disk
Levels: 1,2,3.  This test operates similarly to the hard disk test.  If multiple SCSI hard disks are
present, only the first disk is tested.  Load the SCSI hard disk  drivers in CONFIG.SYS and
AUTOEXEC.BAT before running this test.
Dock slots
This test is unimplemented at this time. 
						

							27Dock keyboard
Levels: 1,2.  This test operates like the Keyboard test except that it uses a standard 101 key
keyboard connected to the dock.  The display shown during this test mirrors the layout of a
standard 101 key keyboard.  Its operation is similar to the internal keyboard test, but for an
external keyboard.
Figure 13 - Dock Keyboard Test Screen
Dock PS2 mouse
Levels: 1,2.  This test operates much in the same way that the internal mouse test works.
Dock EEPROM
Level: 2.  This test checks each of the 512 EEPROM bytes.  Each byte is inverted and written,
then read back to ensure the inverted data is found.  The original data is written back, restoring
the original data.

							28 Desktop Management Interface (DMI)
The Desktop Management Task Force (DMTF) was founded in 1992 by a group of leading
computer manufacturers, including Hewlett-Packard, to define a standard method of managing
the physical and logical components of personal computers.  The result of these efforts is the
Desktop Management Interface (DMI).
Description of DMI
DMI is basically a set of rules for accessing information about a personal computer.  Using DMI,
an application program can determine, for example, which hardware and software components
are present in a personal computer, the operating system that is being used, and the number of
accessory board slots that are available.  Using the DMI interface, a local or remote application
program can check what hardware and software components are installed on your computer,
how well they are working, and whether any needs replacing.
All this information is stored in a special Management Information Format (MIF) file, installed on
each personal computer as part of the DMI package.  The MIF file specifies information about
components at two levels:
· Groups contain all the information concerning a particular hardware or software
component.  If more than one component of the same type is present, as is often the
case with serial ports and hard disk drives, a group is repeated.
· Attributes are specific items of information relating to a group.  Attributes of the Mouse
group, for example, include the number of mouse buttons and the name and version
number of the mouse driver being used.
Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced features
of HP OmniBook Notebook PCs to be managed with DMI. These extensions cover:
· Administrator and user passwords.
· Tattooing: a string of characters that uniquely identifies the computer.
Note: The DMI software package included with the OmniBook can only be used with the HP
OmniBook Notebook PC.
For full details of the structure of the MIF file, including an explanation of the meaning of the
fields of groups and attributes and how to write an application program that accesses this
information, you can access the DMTF FTP server ftp.dmtf.org or the DMTF Web Pages at the
URL www.dmtf.org .
Contents of the DMI Package
The DMI software and associated documentation is supplied either pre-installed on the
OmniBook’s hard disk drive or on two flexible disks.  The contents of the package are the same
in both cases.
Since the information accessed by the DMI software is specific to a particular computer, it must
be installed on each computer separately. 
						

							29The following software is supplied with the DMI package:
· A Microsoft Windows utility, SETUP.EXE, to install and initialize the DMI software.
· A Windows utility, HP TopTools.  After DMI is installed, this utility can be used to display
information about the computer through the DMI.
· A Management Information Format (MIF) file.  This file contains information about
everything on the computer that can be controlled using DMI facilities, and is initialized
during installation.
· A component code, identifying the version of MIF file to use for specific models of HP
OmniBook Notebook PCs.
· Windows-compatible DMTF Service Layer software, which controls access to the DMI.
· A client agent.  The HP Remote DMI Agent is a DMI application and also a network
server-side stream-based application.  The Remote Agent is listening for Remote
Application connection requests.  If the main window of the Remote Agent is hidden, then
no icon will appear on the screen when it is running.

							30Installing the DMI Package from Windows 95
The DMI package is included with the OmniBook, but it must be properly installed before it can
be used.  The following steps explain how.
To install the DMI preloaded on the hard disk:
· Start Windows 95, if it is not already running.
· Click on “Start”.
· Go to “Programs - HP DMI”.
· Select and run “SETUP”.
To alternatively install the DMI from floppy disks;
· Copy the DMI software from the \omnibook\drivers\win95\dmi directory of either the hard
disk or Recovery CD to two floppy diskettes (copy contents of the \disk1 subdirectory to
diskette #1 and contents of the \disk2 subdirectory to diskette #2).
· Start Windows 95, if it is not already running.
· Insert diskette #1 into the floppy drive.
· Select and run the SETUP program from the diskette #1.
Uninstalling the DMI Package from Windows 95
· Go to the HP DMI group.
· Launch the program “Uninstall DMI”.
· Reboot the PC.
Using the DMI Interface
For a complete explanation of how to fully take advantage of DMI, the following documentation
is provided with the OmniBook:
· A README.TXT file.
· A Windows online help file describing Hewlett-Packard’s implementation of DMI (group and
attribute definitions).  Since not all Hewlett-Packard enhanced features are supported on all
models, this document also describes any restrictions that apply.
