7)  Verifying Installation of the Driver

    For Windows 9x:

        2. Open "System" in "Control Panel" and select the "Device Manager".
        3. Select "Hard disk controllers" and check if the "VIA Bus Master
           PCI IDE Controller(Ultra DMA)" controller is existing or not.
        4  If it is then your installation is successful.

    For Windows NT:
        1. Open "Control Panel" from "Start Menu -> Settings"
        2. Select "SCSI Adapters" from "Control Panel".
        3. Check the "Devices" is "VIA bus master IDE drivers" or not.
        4  If it is then your installation is successful.

8) Notes
   *   It is recommended to install the CD-ROM which is not on the same
     channel with the hard drive for the performance issue.

       If you play VCD or DVD abnormally on some CD-ROM or DVD-ROM which
     is on the same channel with hard drive, we recommand you to setup
     the CD-ROM or DVD-ROM on the separatly channel.

   *   You should run the ATAPI ZIP 100MB setup program first for the
     WinNT 3.51/4.0 in order to use ZIP ATAPI 100MB normally on your
     system.

       If you run the VIA Bus Master setup program first and then the ATAPI
     ZIP 100MB setup program. After the ATAPI ZIP 100MB setup program, it
     will disable the VIA Bus Master driver after the installation. You
     could use the following steps to disable the ATAPI ZIP 100MB driver and
     enable the VIA Bus Master driver again.

       1. Double click the "Devices" icon from Control Panel.

       2. Select the service for IDE/ATAPI ZIP drive. (ex. imgatapi)

       3. Press the "Startup" button and select "Disabled".

       4. Press "OK" and reboot computer.

9) Limitation
	1.Display the IDE devices with a ˇ§SCSIˇ¨ word head
	- Win2000 system supports the third party IDE drivers as a fake SCSI miniport 
	  driver. No wonder, even the device is a ATA/ATAPI device she will add a head 
	  mark ˇ§SCSIˇ¨ before the device model name so that the user will misunderstand
	  why the displayed device type is not identical to what he have. 
	  This limitation will not have any side effect to end usre.

	2.Windows 9x/ME will only support total disk size up to 128 GiB limited 
	  by the designation of FAT32 file system.
