INSTALLING WINDOWS 98 ON A SYSTEM RUNNING WINDOWS NT

You cannot install Windows 98 over any version of
Windows NT, but they can exist together on a single
system. However, for compatibility reasons, it is
recommended that you install each to a separate hard
disk or partition. If Windows NT is already installed,
Windows 98 Setup will add itself to the Windows NT boot
menu to allow the user to multi-boot between Windows 98
and Windows NT.

If you can no longer boot Windows NT, you should boot
from the Windows NT recovery disks and choose the Repair
option to restore the Windows NT boot files.

When installing Windows 98 on a system with drives
created with Windows NT, you may receive the following
error:

"Setup has detected that your hard disk has a 64K-cluster
FAT partition. Because ScanDisk does not work on disks
with this cluster size, Setup cannot continue. To complete
Setup , you must repartition your hard disk, format the
partition with a FAT file system that has a cluster size
of 32K or less, and then restart Setup."

Running Setup with the "/is" parameter (e.g., Setup /is)
will bypass ScanDisk and avoid this problem.

INSTALLING WINDOWS 98 ON A SYSTEM RUNNING OS/2
Setup will not run on OS/2. You need to start MS-DOS
and run Setup from the MS-DOS prompt.

NOTE: If you are upgrading over OS/2 on an HPFS partition,
you must have your OS/2 disk 1 available during Setup.

If you start MS-DOS from a floppy disk and then run
Setup, you will no longer be able to start OS/2 after
Windows 98 has been installed. You must delete the
Autoexec.bat and Config.sys files that OS/2 uses before
running Windows 98 Setup.

If you want to remove OS/2 from your computer after you
have installed Windows 98:

1. Back up the data files you want to keep onto a
   floppy disk or network drive.
2. Delete the files in each of your OS/2 directories and
   subdirectories, and then delete the OS/2 directories.
3. In My Computer or Windows Explorer, click View, click
   Options, and click Show All Files. Then, delete the
   following OS/2 files:

 Ea data.sf
 OS2ldr.msg
 OS2krnl
 OS2boot
 Wp data.sf
