H Introduction » - T z I à8 á. à: Ë à9 á+ á, á- ÿ Introduction SAB Diskette Utility is a Windows 3 application that provides the user with a set of services that makes the copying, comparing, and formatting of diskette s a pleasure instead of a pain. It makes use of the Input/Output ( IOCTL ) interface to read/format/write a track at a time.. It will copy, in a single pass, the entire contents of a diskette, at the sector level, into an image either in memory or in a temporary hard disk file. The image can then be used to produce multiple copies of the original diskette. The system makes use of Windows 3 Messages and Timers to work cooperatively with other Windows 3 applications. It can be run entirely in Iconic mode . ( ( ! § License È ( 8 B I á$ ÿ License THIS PRODUCT IS NOT FREE. IT IS OFFERED ON A "SHAREWARE" BASIS.

It will also enable the menu items that require a completed diskette image to work ( Compare and Write ). * ü * ! 4 Comparingò ¡ * ò Q t I àC àD à8 á3 à9 à: à< ÿ Compare The Compare command compares the contents of an image in memory or an image on hard disk with the contents of a diskette . It uses the Input/Output Control read ( IOCTL READ ) subfunction to read all of the sector s on a track at a time into memory. It then compares the contents of the track with the stored image. If there are no differences it will proceed to the next track. If there are any differences it will ask the users whether to stop the compare function or to continue anyway with the next track. It compares all of the tracks on a cylinder before using Windows 3 messages and Timers to give up control to other Windows applications. d # ò p A T I à@ à< à< ÿ To invoke the compare command "click" on the Diskette menu item and then "click" on the Compare submenu item or press the Ctrl key and the C key toget5, '/ , her.

The write command uses Windows 3 messaging and Timers to work cooperatively with other WIndows 3 applications in sharing the systems resources. To invoke the write command "click" on the Diskette menu item and then "click" on the Write submenu item or press the Ctrl and the W key together. A window will open with instructions to insert the diskette into the appropriate diskette drive and press the button corresponding to the drive. Ï õ E \ I à< à< ÿ A truncate option is available that will limit the data written to cylinder s containing allocated clusters. Unallocated cylinder s will be ignored. The verify option defines whether the system will verify data written to a diskette. The write process with the verify option on consists of writing a track's worth of data, reading it back into memory and comparing it with the original information in memory. The format option defines whether the system will always format the output diskette when writing ¼: ±= : to it, never format the output diskette, or format the output diskette only when it cannot read it. The fast start format option indicates that the diskette is not to be check before formatting. á ¨ á 9 D I à: à< ÿ A cancel button is also available to terminate the write command at this point.

! $ Setting Up" ç + . ; H I á, à@ ÿ Setup The Setup command provides the user with the ability to select the appropriate settings for the maximum and minimum Timers , the desired image spooling option, the desired format while writing option, the desired sound setting, and to change diskette drive definitions. The maximum timer kF F kF defines the maximum number of milliseconds (.001 seconds) that the system will allow other applications to run before resuming the current operation. The default setting of 9999 disables the use of this timer. The way the system is designed it should not be necessary to use this timer unless there are a number of not well behaved Windows applications running and Windows is not providing enough time for the system to complete its operations in a reasonable time. It can also be used to convert the system into a not well behaved Windows application by setting it to zero. Please note that setting the maximum timer to zero will also disable the ability to cancel an operation in process. Z . ) $ I ÿ The minimum timer defines the minimum number of milliseconds that the system will wait before even attempting to get scheduled. The default setting of one is necessary to allow DOS applications with PIFs that prompt the user for input to start properly. The way the system is designed it should not be necessary to increase this timer unless the interruption caused by repeated diskette operations is disruptive to time critical applications running at the same time. The use of this timer will increase the time between diskette accesses. Unfortunately Windows 3 does not provide the ability to have other tasks use the CPU while one task is waiting for a diskette operation to complete. Since diskette operations take a relatively long time a series of closely executed ones might prove disruptive to other applications running at the same time. - 9 ) $ I ÿ The drive types define the way the system thinks the drives can be used. It should not be necessary to change this unless a drive is replaced, added, or removed. However, it is possible that the actions of other applications may have changed the drive definitions just before the first use of the system and it therefore failed to define them properly. Select the diskette drive you wish to chÄJ GN kF ange by "clicking" on the drives button. If it is necessary to change a definition simply "click" on the new one. " é 9 " 9 D I ÿ The hard disk spooling option defines whether the system will always use the hard drive for the diskette image, never use the hard drive for the diskette image, or only use the hard drive for the diskette image if insufficient memory is available. The sound option defines whether the system will beep at the end of a diskette operation (compare, format, read, write). The exit option defines whether the system will prompt for confirmation when the user exits the application. © " © ( " ÿ The flash option defines whether the system will flash its window or Icon when a function completes. If flash is not selected the system will pop-up a dialog box immediately after a function completes and make it the active window. If flash is selected the system will flash its window or Icon and wait for the user to make it the active window before displaying the dialog box. , © , ! Ì # " RegisteringÀ , À 1 4 I ÿ Register The Register command may be invoked by holding down the Alt key and press the R key even if the command is not visible on the menu The Register command is used to enter the user's name, company name (if not a personal use license), address, phone number, and the registration key and to print a registration form. The first time the system is used the user's name and address should be entered and saved. The user key is generated by the system at the time the registration information is saved or printed. It will be used as a check that the user information has been correctly processed during the generation of the registration key. x 3 À E \ I ÿ The registration key will be sent to the user after the registration agreement and fee have been received by the author. Once awT 7W KT valid registration key has been entered the Register command will be removed from the menu. The registration type should be selected by "clicking" on the option desired. Please note that the choice of a home use registration will force the company name to "Personal Copy". After all of the information, except the registration key, has been entered a registration form can be printed by pressing the Print button . That will print a registration form and save the user's information. Pressing the Save button will save the information without printing a registration form. Pressing the Cancel button will terminate the registration command without saving the information. \ 3 \ ) $ I á6 ÿ The information is saved in the SAB.INI file. * \ * ! á ÿÿ & First Use· v * · A T I àB àA ÿ First Use The first time SAB Diskette Utility is used it will display a screen that describes the evaluation terms and one that explains the disclaimer. The user has the option to stop the installation process at that time if they do not want to abide by the terms shown by pressing the Cancel button . Pressing the OK button accepts the terms and continues the installation. The menu bar will have all of the menu items disabled except the Exit and Registration commands. The Registration command should be used to enter and save the user's name and address. Once that is done the other commands will be enabled . / · / ! Y % ÿÿ Initialization é / * 5 < I àF á6 ÿ Standard Initialization The SAB Diskette Utility uses a private INI file to store parameters in. The name of the file is SAB.INI . It will be created in the Windows directory the first time the system is used. During initialization the system will obtained the size and position of the main application window the last time the system was used. It will also obtain information stored during the use of some of ø] '^ ø] the commands. This information will be used to initialize options. 4 * 4 ! ÿÿ ÿÿ Special Usage Hints¡ F 4 ¡ [ I á# á* á á á ÿ Special Usage Hints Formatting Multiple Diskettes: Use the SETUP function to change the definition of the diskette drive to a single density. This will eliminate the pop-up menu for density selection. Use the Fast Start option to turn off initial checking of target diskettes. This will significantly speed up the formatting of new (unformatted) diskettes. Using Unformatted Diskettes for Output : Use the DUPLICATE command. Set the truncate option on in the READ screen. Put the diskette to be copied in the diskette drive and select the drive by "clicking" on it. When the WRITE screen comes up turn on the fast start format option. Put the first output diskette in the diskette drive and select the drive by "clicking" on it. When the write finishes put the next output diskette in the drive and press the space bar. Please note that only the allocated cylinders of the input diskette are copied when you use the truncate option and only the allocated cylinders will be formatted on the output diskettes during the write operation. This is the fastest method of duplicating diskettes using unformatted output diskettes All of the files on the output diskettes well be readable but the output diskettes will not be able to be copied using diskcopy because cylinders beyond the allocated ones will not be formatted. ! ë ¡ - 6 > I ÿ The write format option should be set back to automatic when you are finished generating output diskettes. Hardware Problems: If the floppy diskette drive is having hardware problems use the WRITE function verify option to turn on verify when writing diskettes. This will cause a read of data after writing and a compare to the original data. This should only be used if there are hardware problems as it slows ` &f Q` the write operation down significantly. Converting Diskette Media: ` * - ` 6 > I á á ÿ A DOS floppy diskette image-- one with a standard Diskette Parameter Table (DPT) -- can be converted from one media (i.e. 5 1/4) to another (i.e. 3 1/2). For example to copy a 1200KB floppy diskette image to a 3 1/2 floppy diskette: 1. Use the READ function to read the original floppy diskette (i.e. a 1200KB 5 1/4 floppy diskette). 2. Use the SETUP function to change the definition of the target 3 1/2 floppy diskette drive to 1200KB. 3. Use the WRITE function to write the floppy diskette image to the target 3 1/2 floppy diskette drive. © ` © ( " ÿ 4. Use the SETUP function to change the definition of the target 3 1/2 floppy diskette drive back to 720/1440KB. A floppy diskette image can only be written to a higher capacity floppy diskette: 360KB ==> 720KB ==> 1200KB ==> 1440KB. The target floppy diskette must be formatted before using the WRITE function when doing media conversion. The target floppy diskette will have the same usable layout as the original floppy diskette. For example a 1200KB floppy diskette image converted to a 1440KB floppy diskette will still have only 15 sectors per track accessible. The additional three sectors per track will still be physically on the floppy diskette but DOS will not be able to access them. To DOS the 1440KB floppy diskette will look like a 1200KB 5 1/4. However, it will be usable in a 3 1/2 floppy diskette drive. In fact a bootable floppy diskette image will still be bootable. .
© . ! Ì ÿÿÿÿÿÿÿÿSystem Option a . 3 8 I à= á/ ÿ System Option Selecting the System Option indicates that the target diskette is to be made "bootable". This entails copying the DOS boot sector from the C: drive, changing the parameter table to the appropriate values for a Diskette Parameter Table ( DPT ), and installing it as the first sector on the target diskett\n n \n e. The two hidden system files are then copied from the C:\ (root) directory to the target diskette. Finally, the file pointed to by the COMSPEC= environment variable (usually COMMAND.COM) is copied to the target diskette. The diskette can then be used to "boot" from to start DOS. þ Ü þ " ÿ It should be noted that since different vendors sometimes use different names for the system files there isn't any validation check on the names -- the first two files in the root directory of the C: drive are copied. - þ - ! G ÿÿÿÿÿÿÿÿQuick Option à - : F I à= à> à? ÿ Quick Option Selecting the Quick Option indicates that the system is to re-write the DOS boot sector , the FAT s, and the root directory . This should only be used if the target diskette has already been formatted. 2 2 ! Ö ÿÿÿÿÿÿÿÿFast Start Option¤ ~ 2 ¤ & ÿ Fast Start Option Selecting the Fast Start Option indicates that the system is not to check the target diskette to see if it is already formatted at the same density. This option should be used for formatting diskettes that have never been formatted before as it will speed up the process because the system won't try to read the boot sector and then go through error recovery. ) ¤ ) ! ñ ÿÿ , Messages â ) ) $ I ÿ Windows Messages Windows' applications process and send "messages". A "message" contains information about an event that has occurred. For example, "clicking" on a menu item generates a "message". An application can also generate and process user defined "messages". Each portion of the application can be viewed as a closed subsystem that receives a "message", performs a task, and returns control. Part of the task performed might be the generation of another "message". I A T I á/ à< à; à9 à: ÿ SAB Diskette Utility makes use of the Windows messaging system to conu yw Eu ntrol the flow of control through the application. Consider the read command -- it is made up of three sections. The initialization section receives the "message" generated when the read menu item is "clicked". It prompts for the diskette and invokes a service routine to analyze the Diskette Parameter Table ( DPT ) and determine the number of cylinder s, head s, and sector s/ track . It then sets the current cylinder, head, and track variables to zero and sends a "message" to the read cylinder section. ' ' % I ÿ The read cylinder section reads all of the sectors on a cylinder and stores them. It then increments the cylinder variable and checks to see if there are more cylinders to read. If there are more cylinders to read it sends a "message" to itself to schedule the next cylinder read. If there aren't any more cylinders to read it sends a "message" to the read termination routine which displays the read completed message and then ends without sending any "messages". The "messages" aren't sent immediately. They are placed into a holding variable and only sent if Windows indicates that there isn't any other work available for it to schedule. At that point the system places the message into the applications queue and it is processed and the function scheduled. ' ' ' ! Þ + - Timers« x ' · 3 8 I á+ á# ÿ Timers SAB Diskette Utility can use Windows' timers to control the scheduling of its internal operations. The way the system uses the timers is to start a timer and request that Windows send a special " message " when the time interval ends. That "message" causes a function to execute. Consider the maximum timer available through the setup . Let us assume that a read cylinder operation has just completed and that there are more cylinders to read. The system puts a read cylinder "message" into a holding variable. The "message" will normally be sent the next time Windows has nothing to do. However, if the ma6} ]} 6} ximum timer value has be set the system will also start a timer. If Windows has nothing to do before the timer expires the "message" will be sent and, as part of the application code that does that, the timer will be stopped. If Windows does not run out of other things to do before the timer expires a timer "message" will be sent to the application. When the application receives the "message" it will check and see that it has a "message" to send and send it at that time scheduling the next read cylinder cycle. 1 · 1 ! @ , / Iconic Operation/ 1 / ) $ I ÿ Iconic Operation SAB Diskette Utility can operate completely in the Iconic mode. The Iconic mode is when an application's window has been minimized. It then normally displays an Icon in the lower portion of the display. The system monitors changes to and from the Iconic mode. When the user puts the system into the Iconic mode it modifies the system menu by adding all of the menu items that would normally appear on the menu bar. It removes the menu items when the user takes the system out of Iconic mode. à ½ / à # I ÿ The system will also use the space normally occupied by an Icon to display the current cylinder for read, compare, format, and write operations. Otherwise it will display its own Icon. & à & ! L / 0 IOCTL Ó & - , I á0 ÿ IOCTL Input/Output Control (IOCTL) is a method of communicating directly with a device driver. SAB Diskette Utility uses the set of subfunctions associated with generic I/O control for block devices. The IOCTL interface is accessed through an interrupt call (INT 21H -- the general DOS interrupt -- with AH(function) = 44H, AL(subfunction) = 0DH, BL = drive number, and CH = 08H) using a Parameter Block pointed to by DS:DX.

These would normally include the device type, number of sectors per track, and total number of sectors. Also set the number of sectors in track in the word at offset 26H and follow it with a pair of words for each sector. The first word is the sector number starting with one and the second word of the pair is the number of bytes in the sector. It should always be 512 (200H). Set the special function field -- offset 00H -- to 05H (it seems to work). Point DS:DX to the parameter block. Set CL to 40H.

Ó ! ! ¾ : E r ! + ( ° ÿ Diskette A form of removable storage media -- sometimes also called a floppy disk. It consists of an outer protective envelop around a thin circular piece of magnetic media. It is inserted into a diskette drive that contains two sets of read/write heads -- one for the top layer of the magnetic media and one for the bottom layer. The read/write heads can only move along a single line from the outer edge of the diskette toward the center and back. The heads move in fixed increments. The diskette rotates in the drive and this allows the heads to access a circular section of the magnetic media for each position. ! ! ! È = : t ! § ' ° ÿ Sector A sector is the basic unit of storage on diskettes. It consisp· · p· ts of a single block of data -- usually 512 characters -- written or read as a group. The normal format of a diskette has the same number of 512 character sectors on each track. Sectors are first created on a diskette by formatting it. This must be done before data can be stored on the diskette. ! § ! ! Ù 9 8 ¸ ! ¸ ' ° ÿ Track A track consists of the circular area that a single read/write head can access from one position as the diskette revolves in the drive. ! ¸ ! ! ú < ÿÿ Ù ² ! Ù ' ° ÿ Head A head is the electromagnetic device that reads/writes the magnetic patterns on the diskette. A diskette drive has two heads -- one for each side of the magnetic media. ! Ù ! ! 5 F ; í ! ' ° ÿ Cylinder A cylinder consists of the circular area that the read/write heads can access from one position as the diskette revolves in the drive. On a diskette a cylinder would contain two tracks -- on for each of the read/write heads. ! ! ! ] 7 9 < ! < ' ° ÿ Boot Sector The boot sector is the first physical sector on the diskette. It is on the first cylinder on the side of the diskette accessed by the first head. It contains a parameter table that describes the physical structure of the diskette (number of sectors per track and number of cylinders) and its logical layout (reserved sectors, File Allocation Table (FAT) size, number of directory entries in the root directory, etc.). It also contains the "boot program". When an IBM compatible microcomputer starts it checks the A: drive for a diskette. If there is one the systems reads the boot sector into memory and begins executing the code in it. If the diskette has an operating system on it the boot sector will contain a program that will begin loading the operation system. ! < ! ! ¤ B ? w O ! ( " I ° ÿ File Allocation Table (FA¿ ¾¿ ¿ T) The File Allocation Table (FAT) contains one entry for each logical cluster on a diskette. (A logical cluster on a diskette contains either one or two sectors depending on the diskette type.) A file's entry in the directory will contain a pointer to the first cluster of the file. The corresponding entry in the FAT will contain a pointer to the next cluster of the file. The FAT entry for the last cluster of the file will contain hex FFs to indicate that there aren't any more. An entry in the FAT for an unallocated cluster will contain binary zeros. ! ! ! : > G õ ! $ ° ÿ Directory A Directory contains the names of files, their attributes, and their starting locations. The root directory immediately follows the last copy of the File Allocation Table (FAT). Subdirectories are actual files in directory format. ! ! ! ³ E A l ! & I ° ÿ Diskette Drive A diskette drive is the device that the floppy diskette is placed into to read or write. It can be internal to the computer case or in a standalone case. The normal sizes for IBM compatible drives are 3 1/2 inches wide and 5 1/4 inches wide. Each drive has two read/write heads one of which is positioned on each side of the floppy diskette. ! ! ! í @ B Ì § !
