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.

Andreas Kinzler wants not be liable for any special, incidental, consequential, indirect or similar damages due to loose of data or any other reason, even if Andreas Kinzler has been advised of the possibility of such damages. The person using the software bears all risk as to the quality and performance of the software. THROUGH THE USE OF THE EXISTING SOFTWARE AND / OR ENTRY OF THE ENTRANCE - KEY AT THE INSTALLATION EXPLAINS THE USER BEING AGREEMENT WITH O. G. GUARANTEE - AND ++HAFTUNGSAUSSCHLUSS. FURTHERMORE HE/IT AGREES WITH (THE USER), ANDREAS KINZLER FOR NOTHING RESPONSIBLY TO WINDOW-DRESSINGS, EXCEPT THAT THIS SOFTWARE COVERS PLACE ON THE DISKETTE / HARD DISK. 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. 4 appendix Contact to the author FIDO: 2:2455 / 112.58 Internet: akinzler rbg.informa address: Andreas Kinzler Albert-Schweitzer-St 8 55283 Nierstein Tel.: 06133 / 58206 (only in completely important cases) Danksagungen Hauke Hagenhoff. .................
