Professional Version
--------------------

You have purchased the Professional Version of PartitionMagic which
comes with a non-machine-specific license.  This license may be used on
an unlimited number of PCs, one at a time.

Since it is typical to run PartitionMagic direct from diskette, please
be sure to make backup copies of the original diskettes, run
PartitionMagic from the backup diskettes, and keep the originals in a
safe location.

Disk sets: OS/2 and Windows 95
------------------------------

The Professional Version of PartitionMagic comes with two sets of
diskettes and manuals:  one set for OS/2 and DOS and one set for
Windows 95 and DOS.  Use the OS/2 set on any machine with OS/2
installed.

While no changes are allowed to the partition PartitionMagic is
installed to, it is sometimes desirable to install PartitionMagic to a
hard disk.  Installation instructions for each set of diskettes are
given in the respective manual.  (Basically, run SETUP from the first
diskette of the set.) Do not install both sets to the same directory;
some files are named the same.

The functionallity of the two sets is nearly identical.  The OS/2 set
is better suited for machines containing OS/2.  For the OS/2 and DOS
set:

  1.  OS/2's extended attributes are checked when a file system is
      checked.
  2.  Conversion from FAT to HPFS is allowed.
  3.  The command name "PQMAGIC" is an OS/2 executable.
  4.  The DOS executable, "PQMAGICD," uses an OS/2-like user interface.
  5.  "PQMAGICT" is used when booting OS/2 from floppy.
  6.  "IOTEST" is used to test the integrity of disk I/O under OS/2.

For the Windows 95 and DOS set:

  1.  PartitionMagic ignores errors in extended attributes (EAs).  If a
      computer once had OS/2, but does not currently have it, it is
      common for FAT paritions to contain EA errors.  These errors are
      ignored by the versions of PartitionMagic on the DOS set of
      diskettes.
  2.  The command name "PQMAGIC" is a 32-bit DOS executable and uses a
      Windows 95-like user interface.
  3.  The command name "PQMAGICT" starts a text-only, DOS executable
      suitable for use with software to enable computer use by the
      disabled.

The remainder of this file contains information specific to either the
OS/2 or Windows 95 version, depending on which diskette set you are
viewing:

1. License Types
----------------

The Personal Version of PartitionMagic features a machine-specific
license.  The Personal License allows installation or configuration on
two and only two particular machines.  See the *User Guide* for the
license.

The Professional Version of PartitionMagic comes with a
non-machine-specific license.  This license may be used on an unlimited
number of PCs, one at a time.  The Professional License includes
technical support and maintenance updates for one year.

The Enterprise Version is for organizations requiring remote
configuration capabilities at multiple sites.  This license provides
for remote execution which runs unattended through use of a script
file.  The Enterprise License allows simultaneous use and can upgrade
hundreds of users quickly and saves time and travel expense.  For
information on the Enterprise Version of PartitionMagic, contact
PowerQuest Corporate Sales at (801) 226-8977.

2. Changing Your Boot Partition
-------------------------------

If you want to modify your boot partition, you must boot from an
alternate source.  If you have multiple boot partitions, boot from a
partition other than the partition you want to modify.  Otherwise boot
OS/2 or DOS from floppy.  See the *User Guide* for more information.

See the material later in this file for information about drives
containing more than 1024 cylinders, and Text Mode (PQMAGICT.EXE).

3. OS/2 Hardware and Software Bugs
----------------------------------

We have found two serious hardware bugs that can cause corruption of
your hard drive if you use PartitionMagic under OS/2 without first
upgrading your OS/2 software.  There are also two OS/2 CHKDSK bugs that
you should be aware of.  The symptoms are errors SYS0549 and SYS1377.
These four bugs are discussed below.

Model 77
--------

The first bug occurs on PS/2 Model 77 computers and possibly other
computers using a Future Domain SCSI controller.  Make certain that you
have the latest flash BIOS and the latest SCSI driver or you may
experience loss of data or corruption of your hard drive.  IBM has
released a new Future Domain SCSI driver that fixes bugs in the drivers
shipped with Warp FullPack and Warp FixPak WFP_05.  The new driver can
be found in FDWPGA.ZIP, available in the standard places
(CIS:OS2SUPPORT, FTP:software.watson.ibm.com/pub/os2/os2fixes, OS/2
BBS).

Model 77 owners should also make certain they have v3.07 (Rev 7) or
later of the flash BIOS.  The latest BIOS is usually available on the
IBM PC Co.  BBS (919-517-0001) in the Reference Disk Section.  From the
main menu, select "REF DISK" to read and accept the license terms.
Search for "flash" in the Reference Disk file area.  The last time we
checked, the Reference Disk file area was #27 and the filename was
7677flsh.dsk.

PCI Bus
-------

The second serious hardware bug, a sporadic data loss bug, is
restricted to PCI bus computers containing the PC-Tech RZ1000 PCI
controller chip and the CMD 604.  If you have a computer with a PCI
bus, please do NOT use PartitionMagic until you have checked for this
bug.

Use IOTEST to test a computer for the PCI IO bug.  READ THE
INSTRUCTIONS FOR IOTEST BEFORE USING IT!  If the instructions are not
followed carefully, the test itself could trigger the bug which could
destroy data in any or all of your files on any of your drives!  The
instructions for proper use of IOTEST are found in the file,
IOTEST.TXT.

CHKDSK SYS0549 Error
--------------------

PartitionMagic uses a legal, but non-conventional system structure
layout for HPFS partitions.  The layout is within the HPFS file system
specification and, for a healthy partition, CHKDSK will verify the
integrity of that layout.

Should the partition ever require repair, the non-conventional layout
sometimes causes problems for CHKDSK.  CHKDSK gives a SYS0549 error,
claiming no space is available on the drive, even when space is
available.  IBM has opened APAR PJ19300 to track customers needing a
fix for this problem.

CHKDSK SYS1377 Error
--------------------

PartitionMagic sometimes changes the size of the root directory to
facilitate various operations.  OS/2's CHKDSK gives error SYS1377 if
the root directory contains more than 64 root sectors, even though the
FAT file system allows 2047 sectors.

IBM has not yet opened an APAR on this error.  Until a fix is
available, use PartitionMagic to resize the root directory to a smaller
value.

4. Warnings
-----------

- Don't forget to backup your hard drive before using PartitionMagic.
While PartitionMagic has been thoroughly tested and is quite safe,
power failure, operating system bugs, and hardware design bugs can put
your data at risk.  No software program, including PartitionMagic, is
perfect.  Before using any utility that makes such extensive changes to
your hard drive, you should backup your data.

- If you run PartitionMagic from DOS:  Turn off 3rd party disk caches.
Deactivate or unload any TSR programs that access or modify the
partitions being changed.  Exit multitasking software such as Windows
3.1 before starting PartitionMagic.  Do not run PartitionMagic from a
compressed drive.

- With Windows 95, run PartitionMagic using MS-DOS Mode.

- When starting Windows 3.1, it is normal to get an error message
stating that the swap file is corrupt.  Windows 3.1 is designed knowing
that disk utilities may move the clusters of the swap file.  When a
move is detected, the error message is given.  To fix the swap file,
delete the swap file and create it again.  Click on the 386 Enhanced
icon in Control Panel, then on the Virtual Memory button.

- Sometimes using PartitionMagic confuses Windows NT in that Windows NT
changes drive letter assignments.  Use Disk Administrator to change the
drive letters back to the values you prefer.

- This release of PartitionMagic handles 7-bit ASCII filenames.
PartitionMagic does not yet handle full 8-bit character sets such as
Code Page 850 or double byte character sets.  Converting a partition
can produce incorrectly translated filenames.

5. Drives >1024 Cylinders
-------------------------

Under DOS, PartitionMagic can not read cylinders that DOS can not see.
If you have cylinders beyond 1023 that the DOS version of FDISK can't
see, PartitionMagic (DOS executable) won't see them either.

If part of the drive is unaccessible to DOS and contains partitions or
parts of partitions, only the partitions totally accessible to
PartitionMagic are enabled for modifying, even though they may be
displayed.  If part of the extended partition is inaccessible, no
operations are permitted anywhere within it.  If at all possible, use
the Presentation Manager executable (PQMAGIC.EXE) to modify the drive.

Usually in OS/2 Maintenance Mode OS/2 can access the entire drive.
However, if the default driver set loaded for maintenance mode does not
include the drivers necessary for your drive, you will not be able to
access the entire drive until you modify the CONFIG.SYS used to boot
maintenance mode.  Change the CONFIG.SYS used to start Maintenance Mode
to include the same hard disk drivers used by the full OS/2 boot.

6. Updates
----------

Minor updates to PartitionMagic are provided periodically.  They are
available from our BBS (801-226-5608), via anonymous ftp
(ftp.powerquest.com), our web site (www.powerquest.com), and
CompuServe (OS2AVENDOR).  Check regularly to assure you have the latest
bug fixes and minor improvements.
