Uninstall SIO/DIO/QIO driver in Windows Vista/XP/2000

Uninstall the Hi-Speed Serial Card from the Device Manager

1. Plug in the Socket serial card you wish to uninstall

2. Go to Start | Settings | Control Panel and double click on System icon. This will take you to the System Properties

3. Open the Device Manager

In Windows 2000 and XP:

Go to "Hardware" tab and click on "Device Manager" button. Make sure to "View the devices by type"

In Windows Vista:

In the "Tasks Panel", click on the "Device Manager" link /p>

4. Under "Ports (COM & LPT)", select the serial card you want to uninstall

5. Right click and select UNINSTALL

6. If there is a checkbox to delete the driver files, be sure to select it

7. Click OK to confirm the Device Removal

8. Remove the Serial HS I/O Card from your Device

Delete any .INF and .PNF files/p>

1. Open Windows Explorer. Go to Tools and select Folder Options.

2. Make sure the folder view is set to "Show Hidden Files and Folders". Consult your Windows user guide for more information

3. Go to the Windows\Inf folder on your system drive (for Windows 2000 the folder is WINNT\INF)

4. Search for OEMx.INF and OEMx.PNF files where x is a number (example OEM1.INF or OEM102.PNF)

In Windows 2000 and XP:

If you have multiple OEM files it is important that you view each OEM file to find the correct one. For a quick search, open each file and look for the name "socketmobile" and the file name SKTSIOXP.INF. Once you find the file, delete it and also delete the corresponding OEMx.PNF file

In Windows Vista:

Open a DOS prompt window and execute the command "PNPUTIL -e" (don't type the quotes). This will display a list of OEMx files by company and type. Look for the ones labeled Socket and COM to help narrow your search. Then follow the instructions for Windows 2000 and XP to finish deleting these file

Brute Force Method:

You can try moving all OEMx.INF and OEMx.PNF files to a new folder you create inside the inf folder. After you install the new driver you can copy these files back.
