    What is HPFS-Access?



    HPFS-Access is a driver for DOS, which makes possible it you, to grab at your HPFS-Partitionen.  After you have installed HPFS-Access, can grab under 
DOS at HPFS-Partitionen so like you it at FAT-Partitionen are used.

    The features of HPFS-Access in the overview

      - Read and writings (!  !!)
      - Covers only about 8   KB DOS - storage.  If   UMBs are available, are used these in the DOS - version automatically (  autohighload) - Very 
quickly.  In many cases more quickly than the   OS / 2 -   Hpfs - driver - installed   Cache.  Alternatively write-through or write-back



    Shareware version and registration



    This program is expelled after the shareware - principle.  That means, that you may test the program 30 days long.  If you want to use it over this 
time frame out further, so must leave you registered themselves as users.  The use of the program at the end of the 30 days is not allowed.

    If you could not work alone with HPFS-Access, must buy you   soviele licenses, as persons work simultaneously with HPFS-Access.  If you can ensure 
e.g., that in a network with 10 computers, only respectively 2 persons work with HPFS-Access, to buy so need you also only 2 licenses.

    Information for the registration find you in the file "  BESTELL.TXT".  Restraints in the shareware - version



    The   Schreibfa"higkeit becomes after some time of   deaktiviert.
    The restraints look in the current version so:

            During:  20 minutes
      Data quantity:  16 megabytes

    Please you do not take advantage of this limit up to the last second, since you could lose otherwise data.  Are e.g. in a   Editor, can store you at 
the end of the time no more.
    Similar counts for the limit of the data quantity.

    This limit does not contain the registered   Vollversion.  Guarantee - and exclusion from liability

    The entrance - key sounds:  "  I   AGREE" (without quotation marks)



      Hardwarevoraussetz



    Required becomes a PC with 386+ (32 - bit - CPU) and at least 2   MB   RAM.    Softwarevoraussetz



    HPFS-Access can become with following DOS - versions   benuzt.  Other DOS - versions are NOT supported.

      MING - DOS 5
      MING - DOS 6.0, 6.2x
        Dr - DOS 6
      PC - DOS 6
        Novell DOS 7

    It is supported in addition Windows 3.1.  A   Xms - driver must be installed.



    Use



    There are 4 versions of the driver.

      DOS_GER.EXE (DOS - version with German texts) WIN_GER.EXE (  Win - version with German texts) DOS_ENG.EXE (DOS - version with English texts) WIN_ENG.EXE 
(  Win - version with English texts) The DOS - version of the driver can be used exclusively under DOS.  The   Win - version can be used under DOS and 
Windows 3.1.


    Preparations for Windows 3.1:

      If you would like to use the   Win - version and want to start also Windows, then must be entered previously the driver'VHPFSD.386'in 
the'system.ini'.

      That can look for example so:

        [386Enh]
        ...
        ...
        device=vhpfsd.386
        ...
        ...

      Please you do not forget the file'VHPFSD.386'in the Windows - system - list to copy.


    Install the driver:

      There are 2 possibilities.

          a) Appeal the EXE-Files without parameters

           In this case HPFS-Access looks for for HPFS-Partitionen and attributes these free DOS -   Laufwerksbuchsta.
           Maximum 4   Partitionen are bound.   b) appeal with parameters


          

The syntax of the parameters is:

               EXEFILE   buchstabe =   partitionsnummer [  cachegro"sse [  T /   B]] [,.  ..]

           A couple of examples for the clarification:

               EXEFILE x=2, y=1

Them 2.  HPFS-Partition becomes the drive letter X:
if the 1. HPFS-Partition associated (if this is free) and becomes   Y:  associated


               EXEFILE l=3 1024

  L becomes the 3. HPFS-Partition:  associated.  For these   Partition 1024   KB are used   Cache


               EXEFILE z=1 512t, m=3 256w

  Z becomes the 1. HPFS-Partition:  associated.  These   Partition uses 512   KB   Cache - storage.  There is used write-through.

M becomes the 3. HPFS-Partition:  associated.  There is used   write -   back.  The   Cachegro"sse is 256   KB


           If you wish optimal performance, then must be the   Cachegro"sse a   Partition in Kbytes larger, than which   Partitions divided - large in 
megabytes   duch 4.

           Have e.g. a 800 megabyte large   Partition and want you optimal performance for these   Partition, then must be the   Cache for these   
Partition at least 200   KB large.


      Deinstallieren of the driver:

      If the driver is installed, then becomes at the appeal the EXE-Files of the drivers   deinstalliert.
      Please   deinstallieren you the driver only with the version, which is installed just (DOS /   WIN and/or   GER / NARROWLY)




    What do at questions and problems?



    If you do not come further, to find then try you please first the answer on your questions and problems in this small   FAQ.  If you should not yet 
come always further or have still questions, then turn you please to one of my network addresses.

    I am pleased over inspirations and (constructive) criticism;  -)))   Q:  My Windows starts no more.  Has shut that which with the Vhpfsd.386 - driver?

      A:  Very incredibly.    Rebooten you and start you Windows newly.  If it not yet go then always, then remove you the   Vhpfsd - driver and to start 
try you Windows again (after a   Reboot).  If it not yet go then always, does not lie the error in   VHPFSD.  If it goes now, then note you please the 
error message and send you me a   Mail.



    2 problems and safety references



    - Backups

      Please you prepare before the first use of HPFS-Access and then at stated intervals backups of your data.  Secure please also   Fat - drives or other   
Partitionen.

    - Storage managers

      I recommend you, to use no other storage managers, as them, which were at your DOS - version thereby.
        QEMM should function now.

    - Installed   Cache

      Please you keep at the current safety precaution if you use the Write-back-Cache.

    - Other   Cache - programs

      Use no other   Cache - programs with write-back.

    - (  E) IDE-Kontroller

      HPFS-Access supports hard disks with more than 1024 cylinders.  Indeed the process is not standardized to this and can lead thus to problems.  OATHS 
-   Kontroller must be pursued in the mode NORMALLY.  The versions known me of'Ontrack'support not more than 1024 cylinders.

    -   SCSI

      With   Scsi - hard disks there should be no problems.  I use personally my driver on a 1.2G-SCSI-HPFS-Parti.  Up until now there was still never a 
problem.

    - DOS   Taskswitcher /   Multitasker

      Please you do not use these programs.  That counts completely especially for   Novell DOS 7.

    - Windows

      Do not copy Windows itself on HPFS-Partitionen.

    -   CHKDSK

      If you leave run at stated intervals   CHKDSK of   OS / 2.  It has occurred already, that the   Hpfs - driver of   OS has not left behind / 2 one 
flawless structure.  HPFS-Access reacts very sensitively to structure errors.



    3 How functions HPFS-Access



    For DOS are HPFS-Partitionen network drives.  That protects from it, that programs grab like   Defragmenter or   Diskeditoren at it.  With DOS the most 
sure way is that besides, to bind a   Filesystem - driver.

    Fundamentally counts, that DOS was prepared for networks or   installierbare   Filesysteme never.  That it is altogether possible today, to bind 
networks in DOS, lies in it, that one of late interfaces has invented.  To this point in time was a clean solution naturally no more possible.  Completely 
differently at   OS / 2.  Here the possibility was anticipated from the beginning, to bind   Filesysteme.

    Under   OS / 2 a   Hpfs - driver has been able to imagine everything which one.  A good concept and much storage.  Under DOS everything looks that 
completely differently.  Here storage stands hardly at the disposal.  The HPFS-Filesystem needs however several hundred Kbytes around altogether write to 
be able to do.  If one would take for it the conventional storage of DOS, would run almost no program more (because of storage defect).  The problem is, 
that the storage is needed however, to make possible the   Schreibfa"higkeite.  One could get along of course with less, which however very at the expense 
of the safety would go.  Thus HPFS-Access has an installed 32 - bit -   Tsr -   dos / WIN-Extender.  The real driver exists to 100% of 32 - bit -   
Protected -   Mod.

    With it the storage problem is solved.  Indeed problems with   inkompatiblen catch now storage managers at (see above).  Programs, which a DOS -   
Extender use (  Borland   Pascal,   Borland C++,   WATCOM   C / C++), put indeed no problem there and functio

ns flawlessly.

    The linking a   Caches (counts also for   SMARTDRIVE,.  ..)  IF DOS is very difficult under DOS, since also here does not make available the sure 
environment for such programs.  Thus you should use no other   Cache - programs besides HPFS-Access, since these otherwise   ungewu"nschte could call forth 
side-effects.  For it HPFS-Access can however neither nor the other   Cache - program something.
