where (n) is a Windows XP assigned number. Depending on the system configuration
you may have several of these oem(n) files. You will need to locate which one is for the
RocketPort 550 / BroadPort 550 drivers.
Note that Windows explorer may not display the .inf extension.
The .inf files are ASCII file and so you can open them under notepad (note
the .PNF is NOT an ASCII file).
To find the oem file assigned to the RocketPort 550 / BroadPort 550 you
can open each oem(n).file as required and look for the ‘Rckt550.inf’ string in
the comment field.
Once you know which oem(n).inf file is the copy, then delete it and the
corresponding .PNF file.
Note: You could use the Windows explorer ‘search’ feature to find the file.
i) Left click toolbar ‘search’ icon
ii) Enter ‘oem*.inf’ (without the quotes) into the search for... edit box
iii) Enter ‘Rckt550.in’ (without the quotes) into the Containing text edit
box
iv) Enter ‘\WINDOWS\inf’ (without the quotes) into the Look in
edit box
v) Left click the Search Now button
The name will appear in the search results. Note that the extension may not

If we assume that the filename is oem0 then the files to delete would be
oem0.inf
oem0.PNF
Note that explorer may not display the .inf extension.
