Specified tests
Checking for board as a PCI resource
WARNING To avoid a possible shock hazard, always turn OFF your computer
and any external circuits connected to the KPCI-PIO32IOA or
KPCI-PDISO8A board before removing or replacing the board.
CAUTION The test outlined in this subsection involves handling of the circuit
board. Handle the board at the mounting bracket, using a grounded
wrist strap. Do not touch the circuit traces or connector contacts. If
you do not have a grounded wrist strap, periodically discharge static
electricity by placing one hand firmly on a grounded metal portion
of the computer chassis.
Always reinstall the cover before turning the computer ON.
NOTE The following procedure depends on the Plug and Play capability of
Windows. If your computer operating system is Windows NT, you must
use a different procedure to detect the board as a PCI resource. Consult
your Windows NT documentation.
The following procedure provides details to help you determine whether Windows Plug and Play
finds your KPCI-PIO32IOA or KPCI-PDISO8A board as a PCI resource.
1. Determine the PCI resources that Plug and Play detects before any KPCI-PIO32IOA and
KPCI-PDISO8A boards are installed. Proceed as follows:
a. Insert a blank diskette, or any diskette that you are sure is unbootable, into the A: drive.
b. Turn ON the computer and allow it to start the boot cycle.
The boot cycle stalls at a text screen listing system characteristics and resources and say-
ing at the bottom:
Non-system disk or disk error. Replace and press any key when
ready.
NOTE This system characteristics and resources screen is normally displayed
only fleetingly during the boot cycle. Having an unbootable diskette in
your computer automatically stops the boot cycle at this screen, allow-
ing for convenient viewing. This is not harmful to your computer. The
more common approach—using the
P
AUSE
key to pause the boot cycle at
this screen—requires fast reflexes with some systems.
c. Note the displayed list of PCI devices under a heading something like PCI device
listing… If you have a printer, print the screen by pressing the PRINT SCREEN key.
d. Remove the diskette and allow the boot cycle to finish.
2. Install a good board—a KPCI-PIO32IOA and KPCI-PDISO8A board that you know is fully
functional—as follows:
a. Shut down Windows, and turn OFF power to the host computer.
b. Install the good board in a slot from which you removed a potentially faulty board. Refer
to Section 3 for board installation instructions.
c. Reinstall the cover of the computer.
NOTE
If you removed more than one board in step 1, install only one good
board in one expansion slot.
Do not connect any external circuits to the board at this point.
