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:
IRQ#:
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
This will cause the Base I/O Address of the modem to be preset to a specific
value.
FC00
11
/P7900
25
