2. Diskettes with the Pack Version
----------------------------------

The Pack Version of PartitionMagic comes with two diskettes: 

     Disk 1 of 2 contains a DOS executable that allows you to modify Windows
     95, Windows, OS/2 and DOS partitions. 

     Disk 2 of 2 contains two OS/2 executables that allow you to run
     PartitionMagic when booting OS/2 from the floppy, and sometimes when
     running OS/2 presentation manager.  

If you have DOS, we suggest you use the DOS executable on disk 1 of 2.
However, if you do not have access to DOS or need to use the Convert feature
(allows conversion from FAT to HPFS) then we recommend you use PQMAGICT.EXE or
PQMAGIC.EXE located on disk 2 of 2.  See Starting and Running PartitionMagic
in the next section for specific instructions.


3. Starting and Running PartitionMagic
--------------------------------------

NOTE: This section replaces pages 27-32 in the *User Guide*.

PartitionMagic is designed to run from the floppy drive.   No installation to
the hard drive is required. To run PartitionMagic from the floppy drive:

Step 1:   If you are using:   

     OS/2 - Boot DOS. Proceed to Step 2.
     
     Windows 95 - Exit to MS-DOS mode by clicking Start, then Shut Down from
     the Taskbar.  In the "Shut Down Windows" menu select "Restart the
     computer in MS-DOS mode" and then click Yes.  Proceed to Step 2.

     Windows - Exit to DOS by selecting Exit Windows from the Program Manager
     File menu.  Then select OK.  Proceed to Step 2.

     DOS - Proceed to Step 2.

Note: You may need to install a DOS mouse driver to use a mouse with
PartitionMagic. Consult your mouse documentation for instructions. You can
also navigate through PartitionMagic using only the keyboard. See pages 46-50
in the *User Guide* for instructions.

Step 2:   Once in DOS or MS-DOS mode, insert PartitionMagic Disk 1 of 2 into
the floppy drive, type A:\PQMAGICD and then press Enter.

Hint: When running DOS, PartitionMagic defaults to a 640x480 screen
resolution.  If you want to specify a resolution of 800x600, start
PartitionMagic by typing A:\PQMAGICD /800

Note: If you only run OS/2 and do not have access to DOS, you can use Disk 2
of 2 and run PartitionMagic after booting OS/2 from floppy.  See "Starting
PartitionMagic from OS/2 Maintenance Mode" on pages 33-34 of the *User Guide*.
In limited circumstances, you can use the native OS/2 Graphical User Interface
(GUI).  To access the native OS/2 GUI:

   -From Presentation Manager, open an OS/2 prompt.  
   -Insert PartitionMagic disk 2 of 2, type A:\PQMAGIC and then press Enter. 

(If you receive an error message about open files then see pages 33-34 of the
*User Guide*.)


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.

- CD-ROM USERS: When you create a new partition, it will be assigned a drive
letter in sequential order. The CD-ROM drive letter will default to the last
available letter. This will require you to reinstall the programs that run
from CD-ROM so that they will recognize the new drive letter. To prevent the
drive letter from changing in the future, you may want to assign a higher
drive letter such as M: or N: to the CD-ROM for DOS or Windows 95.  For more
information on how CD-ROM drives or any form of removable media is affected
when using PartitionMagic, see the Technical Support area on our home page at
http://www.powerquest.com.

- 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.

- Avoid creating Multiple Visible Primaries (MVPs) if you are using OS/2 or
Windows 95. Because OS/2 and Windows 95 do not support MVPs, creating them can
cause data loss.

- After using PartitionMagic, it is normal to get an error message when
starting Windows 3.1 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 changes made by PartitionMagic confuse Windows NT, which then
assigns drive letters incorrectly.  Use Disk Administrator to assign the drive
letters to the values you prefer.  Windows NT may also fail to boot if the
boot partition's arc name changes.  See Microsoft Knowledge Base articles
Q102873, Q103673 and Q102877 for more information.

- This release of PartitionMagic handles ASCII filenames.  PartitionMagic does
not yet handle double byte character sets such as Japanese.  Converting a
partition can produce incorrectly translated filenames.


5. Changing Your Boot Partition
-------------------------------

If you want to modify your OS/2 boot partition, you must boot OS/2 from an
alternate source, or boot DOS.  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).



6. Ignore OS/2 EA Errors on FAT
-------------------------------

The Preferences menu in Release 2.03 contains a new menu item: "Ignore OS/2 EA
Errors on FAT."  When on, a check mark next to the menu item indicates that
OS/2 EA errors on FAT partitions will be ignored.  This preference should be
turned off when modifying a computer upon which OS/2 is currently loaded. It
may be turned on if EA errors prevent modifications on a computer on which
OS/2 is no longer loaded.


7. 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
resolved APAR PJ19300.  The fix is available in FixPak 11 or later and can be
downloaded at http://www.ibm.com.

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.


8. Drives >1024 Cylinders
-------------------------

Under DOS, PartitionMagic cannot read cylinders that DOS cannot see.  If you
have cylinders beyond 1023 that the DOS version of FDISK cannot 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.


9. 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, Other Vendors section). 
Check regularly to assure you have the latest bug fixes and minor
improvements.
