PCI.TXT - PCI Installation Programs for DOS
*********************************************************************
Note: Please read this entire document before installing PCI cards.
I. Installing PCI Cards in DOS
1. Install the PCI communications adapter into an available
PCI slot in your system. Refer to the Hardware Installation
section in the product's manual. Multiple cards may be installed
in a single system.
2. Boot the machine to DOS.
3. The system BIOS will assign I/O addresses and an interrupt to
each PCI communications adapter present in the system during each
system boot. The FINDPCI.EXE utility in this directory is used to
display current resource assignments for each card.
4. FINDPCI.EXE will display resources for each detected card in the
system. These settings are also stored in the file PCI.INI, located
in the same directory as FINDPCI.EXE. The following is a sample output.
; PCI.INI
[CARD1]
MODEL=7201
BUS=0
DEVICE=15
FUNCTION=0
PORT1=160
PORT2=168
IRQ=15
[CARD2]
MODEL=7201
BUS=0
DEVICE=16
FUNCTION=0
PORT1=190
PORT2=198
IRQ=10
Each card installed in your system should have a [CARDx] entry displayed
by FINDPCI.EXE.
II. Determining Resources Assigned to Each Installed PCI Card
1. Each system motherboard organizes its physical PCI slots according to the
current PCI specification. There is not a fixed order or number of slots
for each motherboard.
2. To determine which resources correspond to which PCI card, you may want
to add the cards one at a time and run FINDPCI.EXE after each card is
added. Each PCI slot will have a corresponding BUS, DEVICE, and FUNCTION
number. These numbers uniquely identify that slot when running these DOS
utilities. Note the slot data for each card that you install.
III. Configuring PCI Cards in DOS
1. After all PCI cards have been installed a [CARDx] section for each
card will appear in the PCI.INI file created by FINDPCI.EXE.
2. The SETPCI.EXE utility is used to modify any I/O resource assignments
for PCI communication ports. Interrupt assignments may not be modified
since variation in motherboard interrupt routing techniques makes
modification through the BIOS unreliable.
3. To modify the assigned I/O resources for any PCI port, edit the PORTx value
in the PCI.INI file and run SETPCI.EXE. In the above example, changing the
PORT1=160 line to PORT1=3E8 would relocate the first port on CARD1 to address
3E8.
4. SETPCI.EXE uses the following command line syntax. It may be run from the
autoexec.bat file.
SETPCI /f:PCI.INI
IV. Testing PCI Ports in DOS
1. After PCI communication ports have been installed and configured using
the steps above, these ports may be tested using the SSD.EXE utility
found in the /DOS/DIAG directory of this disk. Simply use the current
I/O address and interrupt settings for the card and refer to the directions
for using SSD.EXE found in /DOS/DIAG/DIAG.TXT.
V. Using PCI Cards with the SeaCOM DOS Driver
1. After PCI communication ports have been installed and configured using
the steps above, these ports may be used with the SeaCOM DOS driver. The
driver and documentation are located in the /DOS/DRIVERS directory of this
disk. If the SeaCOM driver is started from the autoexec.bat file, make
sure that the SETPCI /f:PCI.INI line precedes the SeaCOM entry. Run the
setup utility provided with SeaCOM and enter the current port settings for
each PCI COM port that is serviced by the driver.
VI. Troubleshooting PCI Problems
1. Many motherboards offer advanced CMOS options that control the
assignment of system resources to PCI and ISA slots. Check the
CMOS settings during system startup and make sure that an
interrupt and IO range are available for the slot containing the
PCI communication adapter. Contact the supplier of your system
board for further assistance with CMOS configuration.
2. On the Intel TC430HX motherboard if "Use plug and play OS" in the CMOS
settings is selected, the BIOS doesn't appear to configure cards'
IO addresses. FindPCI locates the card, but SSD fails to see ports.
Solutions:
1. Use Windows 95 or another PnP OS.
2. Turn off "Use PnP OS" in CMOS settings.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
