----------------------------------------------------------------

When setting up your system, only one primary partition can be
assessible (active) on each hard disk at any system startup.  On
the other hand, all the logical drives within the extended
partition are accessible, provided their file system formats are
compatible with the starting operating system.  For example, you
have DOS 5.0 in one primary partition and OS/2 2.1 in another
primary partition. One of your logical drives is formatted for
FAT and contains a variety of DOS programs.  You can start the
DOS programs from either of the primary partitions.

It is also important to understand what happens to the drive
mapping if you ADD a hard disk AFTER you install OS/2 2.1.  The
logical drives on your existing hard disk will be remapped.

EXAMPLE OF MAPPING ONE HARD DISK:

NOTE:  The following examples apply to OS/2 2.X and WARP.

If you have this as an existing hard disk set up as shown and
you add a second hard disk to your system.  The primary partition
of the second hard disk will be assigned D. The logical drives of
your first hard disk will be remapped.  The existing logical
drive D becomes E, E becomes F, and so forth.


Primary (Boot Manager) = No drive letter

Primary (DOS 5.0)    |
Primary (OS/2 1.3)   | = C:

Logical Drive        |
  (OS/2 2.1)         | = D:
  ()S/2 WARP)

Logical Drive (Data) | = E:

Logical Drive (Data) | = F:

EXAMPLE OF ADDING ANOTHER HARD DISK OR MAPPING TWO HARD DISKS

OS2 2.1 is in the logical drive assigned a E.  All references to
the drive letter (for example, statements in your CONFIG.SYS and
INI files) have to change. For this reason, it is preferable
to place only logical drives on the hard disk that you are
adding.

NOTE: You can assign OS/2 WARP instead of OS/2 2.1.
