- New Features of v1.54
- =====================
-
- MAXI Form v1.54 has the following new features and improvements over v1.52:
-
- - Supports formatting 420k disks in 1.2 meg drives.
-
- - Improved error detection and handling routines.
-
- - On screen display of type of disk being formatted. (This lets you
- know how MAXI interpreted your command line switches).
-
- - Automatically re-tries formatting a track up to 3 times before
- reporting an error (with verify option on).
-
- - Improved version of SMAX compatible with more hardware BIOS's.
-
- - Automatically determines if you have correct DOS version (3.20 or
- later).
-
-
-
- The Fine Print:
-
- This summary documentation package is provided solely for the benefit
- of getting new users familiarized with the features of the MAXI Form
- program. Complete printed documentation is provided to all registered
- users along with notification of and discounts towards future updates.
-
- MAXI Form is intended to format blank disks only. Because it will
- destroy all existing data on a floppy disk, Herne Data Systems assumes
- no liability for losses caused by misuse or abuse of this product.
- This responsibility rests solely with the end user.
-
- Please note that MAXI Form relies on quirks in the MS-DOS/PC-DOS
- operating system and BIOS ROM's. Although it has been tested on a wide
- variety of systems with DOS versions 3.2x and later, it cannot be
- guaranteed to work with all systems, especially ones which have been
- heavily customized and modified (including the installation of non-
- standard disk drives and controller cards) by the user; nor can it be
- guaranteed to work with future releases of MS/PC-DOS. (Some DOS
- releases may require the use of the special device driver program
- SMAX.COM (outlined later in the documentation) for reliable performance
- with some hardware systems.)
-
- This documentation assumes that the reader is reasonably familiar with
- MS-DOS concepts and terminology and has a basic understanding of how to
- use his/her computer.
-
- MAXI Form is a copyrighted program produced by Herne Data Systems Ltd.. It is
- distributed through user groups and bulletin board systems on the basis of
- 'user supported software' or shareware. While the program and this summary
- documentaion may be freely copied and distributed (provided that the copyright
- notices are NOT REMOVED), each end user is requested to register his or her
- copy with Herne Data Systems Ltd. along with a one time fee of $10.00 (in
- either US or CDN funds). Payment of the registration fee entitles the user to
- a copy of the printed documentation package as well as technical support.

- Introduction:
- ------------
-
- Are you tired of running out of space on your floppy disks? How would you like
- to fit 420k on a 360k disk, 800k on a 720k disk, 1.4 meg on a 1.2 meg disk, or
- an incredible 1.6 meg on a 1.44 meg disk?
-
- Sound impossible? Well not any more!! If you are using DOS version 3.2x or
- later, then the innovative new shareware program from Herne Data Systems called
- MAXI Form is just the thing for you. Using MAXI Form for all your floppy disk
- data storage needs is like getting an extra one and a half disks FREE with
- every box of floppies that you buy!!
-
-
-
- NOTE: In most cases, NO SPECIAL SOFTWARE DRIVER PROGRAMS ARE REQUIRED TO
- ACCESS THESE DISKS FROM DOS. However, in cases where reliable
- standalone operation cannot be achieved (it is a complex function of
- ROM BIOS details, DOS version and disk controller characteristics),
- the simple device driver SMAX.COM can be used to patch the BIOS code
- and provide resident support.
-
- MAXI Form is self documenting to the extent that it can be used by experienced
- MS-DOS users and a suggested registration fee of $10.00 provides you with full
- printed documentation.
-
- In order to use MAXI Form you will need a 100% IBM compatible computer (PC, XT,
- AT, PS/2, Convertible, etc) with at least one 360k 5.25 inch, 1.2 meg 5.25
- inch, 720k 3.5 inch or 1.44 meg 3.5 inch floppy drive. The 1.44 meg drive
- can be used to format 800k 3.5 inch disks; and the 1.2 meg drive can also be
- used to format 420k disks. (Please note that 420k disks formatted in 1.2meg
- drives may not work on all 360k drives. This is due to a physical limitation
- of the 1.2 meg drives, i.e. the read/write head is only half the size as that
- on a standard 360k drive.) External 5.25 inch drives for the PS/2 and most
- laptops are also supported under the given versions of DOS.
-
- Unfortunately, MAXI Formatted disks sometimes do not work reliably with some
- customized OEM versions of MS-DOS. In these cases you will need to use SMAX.COM
- outlined later.
-
- MAXI Form works with all standard display adaptors and monitors
-
-
-
- Starting Up MAXI Form
- ---------------------
-
- MAXI Form relies on command line switches to specify its input parameters. If
- you simply type in:
-
- MAXI <-- (note: in this documentation the symbol <-- is used to
- denote the "return" or "enter" key.)
-
- you will be greeted by an extended sign on message which gives the shareware
- details and a summary of the command line options. The general syntax for the
- command line options is:
-
- MAXI {drive:} [/3] [/H] [/L] [/V] <--
-
- Where {drive:} is either A: or B: corresponding to the physical disk drive
- on which you wish to perform the formatting operation. Use
- of other drive letters will result in an error message.
- This parameter must be explicitly included. MAXI will not
- assume a default value for the drive.
-
- /3 is used to denote a 3.5 inch (720 k or 1.44 meg) disk drive.
- This will give an 800k disk or a 1.6 meg disk. An 800k disk
- can also be formatted on a 1.44 meg 3.5 inch drive.
-
- /H is used to denote a high density (1.2 meg) AT type 5.25 inch
- or 1.44 meg PS/2 type disk drive. This will give a 1.4 meg
- disk or 1.6 meg, respectively.
-
- /L is used to denote a 420k disk in a 1.2 meg drive. This
- should not be used in combination with the /3 or /H.
-
- /V is used to denote a "format with verify". With this option,
- the sectors on each track are read back in just after the
- formatting to make sure that they are OK. A message will be
- displayed during the formatting cycle indicating if any
- tracks had detectable errors. Note that cylinder 0 is
- always tested for errors regardless of the setting of this
- switch. If errors are found on track 0, the formatting
- operation is aborted. /V will automatically re-try a format
- on a track up to 3 times before reporting an error. A
- format operation done without the verify option is
- considerably faster than one done with the verify option.
-
- The /3, /H /L and /V switches are optional. Spaces are not required between
- multiple switches. If only the drive letter is specified, then MAXI Form will
- default to a 420k disk with no verify.
-
- Note: MAXI Form does not check to see what kind of drive is connected as the
- specified device. This allows you the flexibility of, for example,
- creating an 800k 5.25 inch disk in a 1.2 meg drive or an 800k disk in
- a 1.44 meg drive. DO NOT SPECIFY AN 80 TRACK DISK TYPE FOR A 40 TRACK
- (360K 5.25 INCH) DRIVE. THIS MAY CAUSE THE DRIVE TO PHYSICALLY JAM
- UP.
-
-
- When it is ready to go, MAXI Form will prompt you to insert a disk into the
- specified drive. At this point, you can either insert the disk and press <--
- to procede, or press the <escape> key to abort and return to the DOS prompt.
-
- When the formatting is complete, you will be asked to enter a volume label of 1
- to 11 characters. (This is similar to the DOS FORMAT program with the /V option
- specified.)
-
-
-
- Using SMAX.COM
- --------------
-
- SMAX.COM is a memory resident device driver which can be used to improve disk
- reliability with some combinations of hardware and DOS. It is a simple TSR
- (terminate but stay resident) program which patches into the BIOS disk
- interrupt vector (interrupt hex 13) and changes the EOT (end of track, or last
- sector in a track) parameter when it detects a disk read or write operation.
-
- To determine whether or not you need to use SMAX, perform the following simple
- test. Format a disk with MAXI then try to copy a number of relatively long
- files (eg over 16k bytes long) to the new disk using the DOS COPY or XCOPY
- command or equivalent. If you get an error message (such as 'general failure
- reading drive ...' or 'sector not found') then you need to install SMAX to use
- the MAXI formatted disks.
-
- To install SMAX automatically on a cold boot, just insert the following line in
- your AUTOEXEC.BAT file:
-
- SMAX <--
-
- SMAX should only be used with MAXI version 1.5 and later. Earlier versions of
- MAXI Form itself will not run properly with SMAX resident in memory. However,
- the disks produced by earlier versions of MAXI will work fine when accessed
- under SMAX. In addition, SMAX will not interfere with the operation of normal
- DOS disks or hard disks.
