Sycard PCCtest 450/460 CardBus Card (Optional)
The PCCtest 450 and 460 CardBus Cards (revision 1.05) available from Sycard Technology are the
only recommended diagnostic tools that test the functionality of the PCMCIA slots using a PCMCIA
card. Each is a Type II PC Card that works with compatible test software to exercise PCMCIA
functions. (For details, see the Sycard Technology web site: http://www.sycard.com.)
The PCCtest product contains these components:
 
• PCCtest 450 or 460 (revision 1.05) PC Card.
 
• PCCtest 450/460 test software disk. (Software updates are available at the Sycard Technology
web site: http://www.sycard.com.)
 
• Configuration headers (PC Card/16-bit and CardBus/32-bit) that attach to the card.
In addition, you will need this:
 
• CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the Sycard PCMCIA
connector.
The Sycard PCCtest 450 and 460 provide the following tests. See the Sycard documentation for
details about running the tests.

Desktop and Windows Management Interfaces (DMI/WMI)
The Desktop Management Interface (Windows 98) and Windows Management Instrumentation
(Windows 2000) are basically sets of rules for accessing information about a computer. DMI/WMI
allows an application to determine, for example, the operating system being used, which hardware and
software components are in the computer, and possibly whether any of the components need
replacing. A local or remote application can use the DMI/WMI interface to check which hardware and
software components are installed on your computer, and may be able to tell how well they are
working or if they need replacement.
Installing the DMI Package
The DMI package is either preinstalled on the computer’s hard disk or can be downloaded from
http://www.hp.com/toptools (the contents are the same in both cases). The package must be properly
installed before it can be used.
To install the DMI/WMI preloaded on the hard disk:
 1.
 Start Windows, if it is not already running.
 2.
 Click Start, Programs, HP Toptools, Setup.
Using DMI/WMI
For a complete description of how to use DMI/WMI, see the following documentation provided with
the computer:
 
• A README.TXT file: click Start, Programs, HP Toptools, Read me.
 
• A Windows online help file describing Hewlett-Packard’s implementation of DMI/WMI (group
and attribute definitions): click Start, Programs, HP Toptools, HP Toptools Help.
Uninstalling the DMI/WMI Package
 1.
 Click Start, Programs, HP Toptools, Uninstall DMI (Windows 98) or Uninstall WMI
(Windows 2000).
 2.
 Restart the computer.

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.
 Restart the computer.
 2.
 When the HP logo appears, press F2 to enter the BIOS Setup utility.
 3.
 The pointing devices are not active in BIOS Setup, so you will need to use the keyboard to
navigate:
 
• Press the LEFT and RIGHT arrow keys to move among menus.
 
• Press the UP and DOWN arrow keys to move among parameters in a menu.
 
• Press F5 or F6 to move through values for the current parameter, or press ENTER to change a
setting.
 4.
 After you select the options you want, press F10 or use the Exit menu to exit BIOS Setup.
 If the settings cause a conflict between devices during reboot, the system prompts you to run
BIOS Setup, and marks the conflicting settings.
Table 3-7, below, lists the BIOS Setup menus and parameters, and the default values for each.
