Windows 95, Windows NT 3.51, Window NT 3.50 (requires DM upgrade
drivers), OS/2 V3.0 (Warp full pack), and OS/2 V2.0–3.0 (requires DM
upgrade drivers).

Before you install a non-DOS operating system on the drive, install DOS
and Disk Manager and make sure that the drive is bootable. Instructions
for running the dynamic drive overlay with other operating systems are
available in the Disk Manager online manual.

If Disk Manager installs a dynamic drive overlay (DDO) and you do not
need this software to access the full capacity of your drive, you can
remove the dynamic drive overlay without losing your data. However,
you will lose access to the full capacity of your drive unless you have
another method for accessing high-capacity drives (see 

Addressing

Drive-capacity Limitations on the front side of this sheet). Follow the
instructions below to remove a DDO from a drive.

Caution.  Before you attempt to remove a DDO,
make a backup copy of all the data on your hard
disc. Also, run CHKDSK, SCANDISK or a third-
party equivalent to detect and repair any damaged
files before you follow the procedure below. If the
DDO migration program encounters a serious file
problem or is interrupted by a power loss or
hardware failure, the migration will fail and your
data will be lost.

1 Boot the computer to Drive C.

2 Insert your DiscWizard diskette into Drive A.

3 Type  A:\dm to start Disk Manager.

4 Select the 

Select Installation Options Menu.

5 Select 

(M)aintenance Menu.

6 Select 

(M)igrate Dynamic Drive. This program moves the data on

your drive so that it can be accessed without the DDO. The migration
may take up to an hour to complete, depending on the size of your
drive.

7 When the migration program has finished, exit Disk Manager.

8 Remove the diskette and reboot the computer. Enter your system

setup program (see your system manual for details).

9 Configure the hard drive with the Cylinder/Head/Sector parameters

shown for your drive in the table in Section 2, “Configuring Your
Computer,” on the front side of this sheet. Save your changes and
exit the system setup program.

10 When your computer has rebooted, insert the DiscWizard diskette

into drive A.

11 Type  A:\dm and choose the 

Maintenance Menu.

12 Select 

Uninstall (D)isk Manager.

13 Select the correct drive to uninstall.

14 When the uninstall is complete, exit Disk Manager and reboot.

Note. Disk Manager can also remove a drive
overlay placed by the EZ-Drive program. Select
(C)onvert Drive Format from the Maintenance
Menu.

below. This causes the drive to appear to your BIOS as having a capacity
of 2.1 Gbytes.

3 Remount your drive in the computer and replace the computer cover.

4 Insert a bootable DOS diskette into drive A and turn on the computer. It

should boot from drive A and automatically detect the new drive as a
2.1-Gbyte drive.

5 Insert your DiscWizard diskette into drive A and type A:\DM. Then press

ENTER

. This runs the Disk Manager program.

6 Follow the Disk Manager instructions to install the dynamic drive overlay

and to partition and format your new drive to its full capacity.

7 After Disk Manager is done, reboot your system. You should see the

Disk Manager banner and be able to access the full capacity of your new
drive.

If the steps listed above do not remedy this problem, try the following:

•

Make sure the monitor is plugged in and turned on.

•

Check all cards.

•

Make sure the video card is seated in its slot and secured with
mounting screws.

•

Turn off the computer and remove the drive host adapter. If the screen
turns on after you reboot, the host adapter may be incompatible or
defective. If so, see your dealer.

•

Check all cables.

•

Make sure the power supply is adequate for system needs.

•

Reboot the computer and listen to make sure the drive motor starts up. If
the drive is very quiet, it may be difficult to hear its discs reach operating
speed. If the drive motor does not start up, recheck all drive cables.

•

Verify that for each drive, a drive-type is listed in the system setup
program.

•

Try rebooting your computer by pressing the 

CTRL

, 

ALT

 and 

DELETE

 keys

simultaneously. If the drive is recognized after you reboot the system, the
computer BIOS test may be completing before the drive is ready.

One solution is to slow the processor speed during startup. If your
computer has a turbo switch, set it to slow speed before turning the
computer on. If there is no turbo switch, you may be able to use
keyboard commands; see your computer manual for details. After the
computer is up and running, return the processor to the fast speed.

Another solution is to warm-boot your computer after every power-on.

•

Check for I/O address conflicts. To isolate the conflict, verify that the drive
and host adapter are compatible with your computer. Turn off the
computer and remove all the peripheral adapter cards except for  the
video card and host adapter. If the computer recognizes the drive
when you reboot the computer, turn off the computer. Reinstall the
