VESA-IDE channel in your system under WIN95 and utilize 32-bit data 
transfers.


3.  Install the Promise IDE Cache drivers to the Secondary port.

    (NOTE: You only need to install a driver for a secondary controller
           if you have a secondary controller. For example, if you have
           a DC200 or DC4030VL-2 with 4 hard drives, you still only need
           to install the driver once for the Primary controller only)

Promise Technology Inc. PTIATAPI Driver Troubleshooting:
--------------------------------------------------------------
   1. When you restart the computer, check "Hard disk controllers" 
      in Device Manager. This will tell you if the IDE Cache 
      driver is installed correctly or not. If it is not correct,
      reconfigure or remove it and install it again.

   2. Remove DOSDRV.SYS from CONFIG.SYS and PTICTRL.386/PTI13.386
      from SYSTEM.INI.  

   3. If a red X shows up on the driver in Device Manager, high-
      light the driver, click on "System Properties", and then 
      "Resources" to make sure the Basic Configuration is correct. 
      The driver controlling the primary controller should be Basic 
      Configuration 0 (IRQ 14 - Input/Output Range 1F0-1F7), and the 
      driver controlling the secondary controller should be Basic 
      Configuration 1 (IRQ 15 - Input/Output Range 170-177).

   4. If you have more than 3 hard drives (or want to use a drive
      letter after E:), add LASTDRIVE=Z in CONFIG.SYS.

   5. When you shutdown the system, if you do not see the "Safe To 
      Shutdown" message for a long time, press <Enter> two or three 
      times.

   6. You can install a different driver for Primary and 
      Secondary IDE port, and each port needs a driver to support 
      it. For example:
      PTIATAPI driver installed for port 0X1Fx(Primary IDE),
      Standard IDE/ESDI driver installed for port 0X17x(Secondary 
      IDE).

      NOTE: You only need to install a driver for a secondary controller
            if you have a secondary controller. For example, if you have
            a DC4030VL-2 with 4 hard drives, you only need to install 
            the driver for the Primary controller.
