Removal of Drivers/Card
If you need to remove the card from your system or remove the
current driver before installing a possible future driver upgrade:
1.
Click on the B&B Com Port under
Ports (COM & LPT)
and
select Uninstall (right click).
2.
Click on Multifunction Adapters, select the B&B 3PCIO1 Single-
Port Isolated Serial Card. Select
Uninstall.
This step clears the entries in the Registry which cannot be
easily edited under 2000 or XP.
3.
Remove the two sets of driver files from the Windows INF
directory.
See the screen on the next page.
(These are named by the OS in the sequence of installation. On
a clean system they are: Oem0.inf & Oem0.PNF and Oem1.inf
& Oem1.PNF. The .inf versions should be verified by opening it
with Notepad, then checking that it is a B&B Electronics file for
the card. The PNF version is a compiled copy of the same
information.)
You can use the
Find
,
File or Folder
function to search for the
text
3PCIO1 or B&B or 3pci within the files.

You may need to set your Views (under My Computer) to show
all files and folders if the INF directory and .inf files are not
visible. Example after Windows Explorer screen.
