These have been copied from previous posts , overkill I know ,
but should have everthing covered . John .
Go to start, run, type in msconfig, on the general tab, click on
advanced and check if the Force Compatibility mode disk access box is
checked , uncheck if it is .
If you view the information on the Performance tab (Control Panel >
System), you may see a message:
Compatibility Mode Paging reduces overall system performance
Some drives are using MS-DOS compatibility
This means that your floppy disk drive or CD-ROM drive are operating
in MS-DOS compatibility mode. We'll discuss only hard disks operating
in MS-DOS compatibility mode here.
To force Windows to attempt to reinitialize the protected-mode IDE
driver you'll have to remove the noide entry from the registry:
1. Start the Registry Editor
2. Go to HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services
\ VxD \ IOS
3. Delete the NoIDE entry
4. Search your registry for BAD_IDE (You can Search the registry by
pressing F3 while working in the registry editor.
5. Delete any BAD_IDE values you find
Or,
1. Select NOIDE.INF in the \Tools\MTSutil folder on the Windows 98 CD.
2. Right-click NOIDE.INF
-or-
Hold down the Shift key and press the function key F10.
3. Choose Install to remove the NOIDE entry.

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.
There are several reasons why your Hard Disks might be running in
MS-DOS compatibility mode:
An "unsafe" device driver, memory-resident program, or virus hooked
the INT21h or INT13h chain before Windows loaded .
The hard disk controller in your computer was not detected by Windows.
The hard disk controller was removed from the current configuration
in Device Manager .
There is a resource conflict between the hard disk controller and
another hardware device .
The Windows protected-mode driver is missing or damaged .
The Windows 95 32-bit protected-mode disk drivers detected an
unsupportable configuration or incompatible hardware .
Microsoft recently released an update for Windows 95 OSR 2 & OSR 2.1,
to fix a problem that would stop the computer from responding (hang)
while the hard disk was being accessed, when using an IDE (ATA) hard
disk and controller that support Ultra DMA mode.
To install this update, follow these steps:
1.Download the Remideup.exe [143KB] file to an empty folder
2.In Windows Explorer, double-click the Remideup.exe file you
downloaded in step 1
3.Follow the instructions on the screen

My 2 cdrom drive are missing
in system/performance I get message:
Performance status
Memory: 64.0 MB of RAM
System Resources: 72% free
File System: Some drives are using MS-DOS compatibility
Virtual Memory: MS-DOS compatibility mode
Disk Compression: Not installed
PC Cards (PCMCIA): No PC Card sockets are installed.
Select an item, and then click Details for more information.
Compatibility-mode paging reduces overall system performance.
Drive C is using MS-DOS compatibility mode file system.
Drive D is using MS-DOS compatibility mode file system.
Drive E is using MS-DOS compatibility mode file system.
Last time this happened I did an over the top re-install is there an
easier way ?
--------------------------------------
Well there are a few possibilities here.
Re-installation of Windows is not really necessary.
Try these suggestions first.
Go to Device Manager ( Windows key + Pause/Break keys together, then
select Device Manager tab) and see what Conflicts you have in there.
Most probably Hard Disk Controllers will have exclamation marks on
some entries. IE. yellow!
Also check your Autoexedc.bat and Config.sys files for CD-Rom entries,
(Start/Run and type in sysedit) this is normal when you install the
Dos CD-Rom drivers, you don't need them for Windows. Type rem in front
of the entries followed by a space if found, IE. Rem Cd rom blah blah
blah etc. there may be 2-3 entries concerning the Cd-Rom. Then close
down, wait 15 seconds and boot the PC back up again.
Next the Registry, go to this key and see if you have the NOIDE entry
there, in the righthand window.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS
If you have the Win98 CD handy, there is a file on the CD called
Noide.inf ( \tools\mtsutil) right click on the file and select
install, this will remove the NOIDE entry in the registry. Close down
and again wait 15 secs, then boot up the PC again.
Post back results, for this attempt.
Hope this helps.
