Configuring DOS and Windows 3.1X

Note: Not all communications programs are supported under DOS due to PCI

IRQ requirements. Unless your communication program can support IRQ

9 or above and can address nonstandard COM port addresses, it may not

be able to support this modem.

Step 1 After you have installed the modem into your machine, turn on the power

and allow the system to boot normally.

Step 2 After the system has loaded, insert the installation diskette into the computer’s

floppy disk drive. At the command prompt, type:

A:PMDMCFG.EXE

and press ENTER.

Step 3 A message similar to the one shown below will be displayed. (Actual values

will change from system to system)

Found V.90 PCI Data/Fax Modem

-----------------------------

I/O Port: FC00

IRQ#: 11

Step 4 Write down the IRQ Number and Base I/O Address that have been as-

signed to the modem. If the default Base I/O Address is greater than 7900,

you will need to add a statement to your “AUTOEXE.BAT” file to preset

this address to a specific value—go to Step 5.

Note: If your default address is below 7900, skip to Step 6. Before you proceed,

copy the PMDMCFG.EXE file to the root directory of your default hard

drive, usually the C drive.

Step 5 If the default Base I/O Address in Step 3 was greater than 7900, add the

following statement your AUTOEXEC.BAT file:

C:\PMDMCFG /P7900

This will cause the Base I/O Address of the modem to be preset to a specific

value.
