I/O Magic 16X, User Manual

19 

If the Primary and Secondary IDE controllers are present but they have yellow 

exclamation marks, read this: 

The protected-mode driver for the hard disk controller was not properly initialized when 
you started Windows previously. When this occurs, a NOIDE entry is placed in the 
registry, preventing Windows from making future attempts to initialize the protected-
mode driver. You might try to resolve the problem by editing your Registry. 
 
 

WARNING:

 Using Registry Editor incorrectly can cause serious problems that may 

require you to reinstall Windows. I/OMagic cannot guarantee that problems 
resulting from the incorrect use of Registry Editor can be solved. 

“

Use Registry Editor at your own risk.” 

NOTE:

 You should make a backup copy of the registry files (System.dat and User.dat) 

before you edit the registry. 
 

Go to the 

Start button

 then 

Run

 and type 

REGEDIT

 Then go to the following 

directories to remove the NOIDE entry if it is listed. Once removed reboot system. 
 
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\VXD\IOS 
 
After you update the registry, restart Windows. Windows will then attempt to initialize 
the protected-mode driver for the controller. If no problems are encountered, the file 
system and virtual memory will operate in 32-bit mode, and Device Manager will not 
display an exclamation point in a yellow circle for the IDE channels. If the protected-
mode driver is not initialized properly, an error message will be displayed and the 
NOIDE registry entry will be re-created. Windows will use the MS-DOS compatibility 
mode file system the next time you start the computer. 
 

If the DVD-ROM drive is connected to a sound card or controller card, read this: 

Make sure the sound card or controller card are install properly, working properly and 
compatible with with Windows 98 / 95. We do not recommend the use of a sound card 
with Our MagicDVD drive. 

Will my MagicDVD drive read DIVX discs? 

 
DIVX is a form of DVD. DIVX-equipped DVD players will play both DVD and DIVX 
discs. They come with an internal modem and firmware that recognizes DIVX discs.
