Sycard PCCtest 450 CardBus Card (Optional)
The PCCtest 450 CardBus Card (version 1.05) available from Sycard Technology is an optional
diagnostic tool. It is the only recommended tool that tests the functionality of the PCMCIA slots using
a PCMCIA card. It is a Type II CardBus Card that works with compatible test software to exercise
PCMCIA functions. (See the Sycard Technology website, http://www.sycard.com.) The PCCtest 450
product contains these components:
 · PCCtest 450 CardBus Card, version 1.05.
 · PCCtest 450 software disk. (Software updates are available at the Sycard Technology website,
http://www.sycard.com.)
 · Configuration headers (PC Card/16-bit and CardBus/32-bit), which attach to the card.
You will also need:
 · CardBus extender card to avoid wear on the Sycard PCMCIA connector. The Sycard
PCCextend 70 extender card is an example.
The Sycard PCCtest 450 provides the following tests. See the Sycard documentation for details about
running the tests.

Desktop Management Interface (DMI)
The Desktop Management Interface (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, and may be able to tell how well they are working or 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.
Installing the DMI Package
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:
 1. Start Windows, if it is not already running.
 2. Click Start, Programs, HP TopTools for Notebooks (or HP DMI), Setup.
To install the DMI from the OmniBook Recovery CD or from floppy disks:
 1. If you do not have a CD-ROM drive, create installation floppy disks
 · On any computer with a CD-ROM drive, copy the DMI software from the dmi directory of
the Recovery CD (under \omnibook\drivers) to two or more floppy disks (for example, copy
the contents of the \disk1 subdirectory to disk #1).
 · On any computer with World Wide Web access, download the TopTools package from the
OmniBook website (see page vi), then create the floppy disks as directed.
 2. Start Windows, if it is not already running.
 3. Insert the Recovery CD into the CD-ROM drive, or insert disk #1 into the floppy drive.
 4. Select and run the SETUP program from the dmi\disk1 directory on the CD (under
\omnibook\drivers), or from floppy disk #1.
Uninstalling the DMI Package
 1. Click Start, Programs, HP TopTools for Notebooks (or HP DMI), Uninstall DMI.
 2. 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.

Description of DMI
The Desktop Management Interface (DMI) is the result of the efforts of the Desktop Management
Task Force (DMTF). This task force 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.
Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced features of HP
OmniBook computer to be managed with DMI, including features such as passwords and tattooing
(identifying a computer using a unique string of characters).
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 http://www.dmtf.org.
Contents of the DMI Package
The DMI software and associated documentation is supplied either preinstalled on the OmniBook’s
hard disk drive or on two floppy 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. The DMI package included with the OmniBook can be used
only with the OmniBook.
The 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 computers.
 · 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.

BIOS Setup Utility
The BIOS Setup utility provides access to basic configuration settings. It is independent of the
operating system.
Running the BIOS Setup Utility
 1. Close all applications, then shut down Windows and reboot the OmniBook. If necessary, you can
press CTRL+ALT+DEL to reboot.
 2. During reboot, press F2 to start the BIOS Setup utility.
 3. The pointing device or mouse is not active in the BIOS Setup utility. Press the RIGHT and LEFT
arrow keys to move among menus. Press the DOWN and UP arrow keys to move among
parameters in a menu. Press ENTER to change a setting. See the table below for more
information.
 4. After you select the options you want, press F10 or use the Exit menu to exit the BIOS Setup
utility.
 If the settings cause a conflict between devices during reboot, the system prompts you to run
BIOS Setup, and the conflicting settings are marked.
