I have Windows Server 2003 with an Adpatec 2120S controller.
The O/S was installed with the Microsoft o/s controller driver.
How do you unistall the MS driver and install the Adaptec supplied driver?
Is it possible to do this without doing a complete re-install?
I tried to unistall the MS driver but it then forces a reboot and just installs the MS driver again.

    You can use the Driver Update Wizard in the device manager, by double clicking the device, and using the Update button in the driver tab...

    If you need to go further...

    Go to C:\Windows\INF, and do a full text search for "2120S" in the .inf files of that folder. When you get a hit, open the file and verify it is for this HW device. Then rename the *DRIVER*.inf to *DRIVER*.old

    Then if you need to reboot, it shouldnt foce the MS install, and then you can manaullly assign the new drivers based on the INF file for the Adaptec driver...

    Ok, Thanks.
    How will that go since the 2120S is the boot controller?

    Thanks again

    Windows *should* have basic functionality of the device until the device is loaded correctly, as it works until the reboot for the MS to be installed...........
