Appendix : A
Removal of the Windows 98 RocketPort 550 device driver files.
Background
Windows 98 is a plug and play (PnP) operating system and plays an important role in
installing kernel device drivers.
During installation, Windows 98 detects new hardware and starts it’s own installation
program (there is no NT style setup program) which installs the device driver, including
updating the registry, processing user’s response to dialog box questions and entries in
device information files (.INF files).
The .INF files are supplied with the driver. They are ASCII text files and can be viewed
with Notepad. (it’s worth remembering this – you will need it later).
When it comes to un-installation, the PnP philosophy means that the hardware is simply
removed. On restart Windows 98 will not load the drivers and the device manager entries
will not be created. It’s as if the H/W and driver were never installed.
Later, if the hardware is re-installed, then on restart, the PnP system will reload the
driver, update the device manager and re-create any dynamic registry entries.
However under certain circumstances it may be necessary to 100% remove the driver
and all supporting files from the W2K system. Here’s how:-
Procedure
Section 1 assume that the H/W and driver are installed and working. Proceed to direct
section 2, if you desire to remove files and registry entries following an installation
problem.
1. Removal of device manager entry
1.1 Start the ‘Device Manager’. The quickest way is to right click on my computer and
select ‘Properties’ from the pop-up menu. When the ‘System Properties’ dialog
appears, left click the ‘Device Manager’ tab.
The device manager displays device information as a ‘tree structure’. To expand the
entries, click the ‘+’ icon.
1.2 Locate the ‘Multifunction adapters’ entry and expand.
1.3 Right click each ‘Comtrol Europe RocketPort 550......’ entry in turn and select
‘Remove’ from the pop-up menu (or highlight the entry and click the ‘remove’ button ). When
the confirmation dialog appears, click OK.
The device manager RocketPort 550 parent device entry will be removed along with attached COM
ports. NOTE that this operation may take some time to complete. You must be patient as the dialog
may appear to freeze.
