- Overview
- --------
-
- This program isn't just another program to read OS/2 HPFS drives
- under plain DOS. HPFSDOS integrates your HPFS partitions into your DOS
- file system!
-
- When invoked, HPFSDOS scans all hard disks for HPFS partitions, assigns
- each partition to a new drive letter and stays resident.
-
- Then you can forget you ever loaded HPFSDOS (but please don't forget to
- register ;-).
- Your programs will work just as if HPFS partitions were DOS drives -
- you can list files, copy them and even run them from your HPFS drive
- using your favorite DOS tools.
-
- For example, you can use
-
- * A command interpreter, even 4DOS
- * DOS programs - Word, Turbo Pascal, Borland C++, dBase, etc.
- * Windows programs - Ami Pro, Maple V, Win32s programs, etc.
- * Utilities - List, FProt, AMIsetup, Scan, PC Tools, etc.
- * Data - ATM fonts, Source code, etc.
-
- Of course, there are some limitations (you knew it, didn't you!)
-
- * Only files with FAT compatible file names (i.e. 8.3) will be listed
- [might be improved].
- * The HPFS drives are read-only (to protect your valuable data, you
- should never use any other program than OS/2 for writing to HPFS
- drives) [I don't think this will be changed].
- * No support for Extended Attributes.
-
- HPFSDOS is still beta software. However, it has been tested using a
- wide variety of software and DOS operating systems. For example,
- HPFSDOS will work under MSDOS 3.1, 3.2, 3.3, 5.0, 6.x and Novell DOS 7.
- For design reasons, it will not run under DOS 4.x, OS/2 MDOS and
- DR DOS 3.41.
-
-
- Things to watch out for
- -----------------------
-
- * HPFSDOS drives claim to be network drives. This is an elegant way to
- disable sector editors, DOS checkdisk and other programs that
- could crash.
-
- * HPFSDOS drives tell DOS their cluster size was 32 KB. Of course, the
- real HPFS cluster size is only 512 Bytes. This lie will allow DOS to
- recognize your large 2 GB partitions properly.
-
- * The maximum number of HPFS partitions supported is 20.
-
- * HPFSDOS does not sort directory listings. Try "SET DIRCMD=/OGNE"
- instead.
-
- * There is no cache - due to the superior structure of HPFS, access
- is still amazingly fast. Any cache program that caches at the
- Int 13h level OR at Int 21h level can tremendously improve HPFSDOS
- speed (SmartDrive doesn't). HPFSDOS has been optimized to work with
- the HyperDisk cache (Shareware by Roger Cross).
-
- * You should set your TEMP and TMP environment variables to point
- to a FAT directory, e.g.
- SET TEMP=C:\TEMP
- SET TMP=C:\TEMP
- This will allow many programs to run from a read-only drive.
-
- * Ensure "PagingFile" in Windows SYSTEM.INI points to a FAT drive.
-
- * Some programs (like dBase IV) require the current directory to
- be on a FAT drive or else won't run from HPFSDOS drives.
-
- * Free space displayed is always a little higher than under OS/2.
-
- * HPFSDOS eats some of your DOS memory. LoadHigh is recommended.
- [Future versions should require less memory.]
-
- * HPFSDOS can read disk cylinders > 1024 if your BIOS supports this.
- [Please contact the author if you have problems with this
- feature.]
-
- * Drive letters might differ from OS/2.
- Use SWAPDRV X Y to swap drive letters (see enclosed
- documentation SWAPDRV.DOC)!
-
-
-
- Error messages
- --------------
-
- * Loading HPFSDOS:
-
- "DOS 3.10 or higher required."
- "DOS 4.x not supported."
- - Get a new DOS, preferably DOS 5.0 or better
-
- "Your operating system has no CDS support (this program won't run
- under OS/2)!"
- - HPFSDOS will not run under OS/2 MDOS. You can use the "DOS from
- drive A:" feature, however.
-
- "There is no partition table at disk .., sector ..."
- "The partition signature might be damaged."
- - Please check your hard drive (using NDD or FDISK).
-
- "HPFSDOS supports only 20 HPFS partitions."
- "You don't really have that many partitions?"
- - Contact the author for a new HPFSDOS version.
-
- "Cannot mount all partitions - please increase LASTDRIVE!"
- - To get rid of this problem, add "LASTDRIVE=Z" (or any lower
- value which works) to your CONFIG.SYS.
-
- "Drive was improperly stopped. Please run OS/2 CHKDSK!"
- - You didn't shutdown OS/2 properly. There might be some
- inconsistencies in the file system.
-
- "Detected a (possible) HPFS error. Please run OS/2 CHKDSK!"
- - Run OS/2 checkdisk.
-
-
- * During operation:
-
- "Access denied."
- - This is no HPFSDOS error, but a DOS or application error. HPFSDOS
- doesn't allow you to create, change or delete files and returns
- an "access denied" error code to the application.
-
- "HPFSDOS: Disk read error!"
- - Please check your disk (using NDD or a similar tool).
-
- "HPFSDOS: Bad/No ... node!"
- "HPFSDOS: ... sector not found!"
- - Run OS/2 checkdisk.

- Registering
- -----------
-
- Developing HPFSDOS has taken much time. I am sure you will recognize
- my work, so there are no limitations in the shareware version.
-
- You may try this program for 30 days. If you want to continue using
- it, you are expected to register. If you don't like HPFSDOS, simply
- DEL it.
-
- >> If you register this version, you'll get:
- * Free upgrade to version 1.0 & tools as soon as available
- (currently scheduled for July 94).
- Version 1.0 will contain:
- - performance improvements
- - bug fixes?
- - new features
- The HPFSDOS tools, HCOPY and HDIR, will allow you to display all
- files and copy them from your HPFS partitions, with or without
- loading HPFSDOS.
- HCOPY "E:\AmiPro\Docs\What a long file name.SAM" C:\WALFN.SAM
- HDIR E:\AmiPro\Docs
- * ... and prices tend to go up rather than down ;-)

- your order.
