- >>> AT&T MS-DOS 3.2 Release 1.0 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
-
-
- AT&T's MS-DOS*, the operating system for Intel-based Personal Computers,
- provides all of the capabilities of the Disk Operating System from
- Microsoft, plus much more. By managing devices, controlling programs,
- and processing commands, DOS coordinates the operation of the PC. In
- addition to maintaining compatibility with version 2.11 and 3.11 of
- MS-DOS, AT&T's MS-DOS 3.2 provides the PC user with new capabilities such
- as enhanced peripheral support, an automatic installation procedure, an
- on-line help utility, improved documentation, and several new and
- enhanced utilities. AT&T MS-DOS 3.2 R1.0 is shipped with the MS-DOS 3.2
- E1.0 User's Guide and contains 3 floppy disks.
-
- The PC 6310 with MS-DOS 3.2 comes with a unique version of on-line help
- which makes it easier to get the most from your personal computer. The
- on-line help facility provides explanations and instructions for all
- MS-DOS and batch processor commands and specific related DOS topics. It
- enables the user to quickly find the right command to correctly execute
- the required process. The on-line help feature was developed in response
- More: (Y), (N), (NS)? ns(Ctrl-K) or (Ctrl-X) Aborts, (Ctrl-S) Suspends.
- to requests from users, MIS departments and PC resellers.
-
- MIS departments may be interested in taking advantage of the customizing
- capabilities of on-line help to create instantly accessible help screens
- for specific MS-DOS applications.
-
-
- PRODUCT SUPPORT
-
- Technical Assistance
-
- A toll-free Hotline service is available during normal business hours for
- a period of 90 days after the date of purchase, delivery, or AT&T's
- provided installation, whichever is latest. A completed Software
- Registration Card must be returned to AT&T within 5 days of this date in
- order to take advantage of the Hotline service. The Hotline assists in
- usage and problem diagnosis and handles requests for media replacement
- under the limited warranty. For assistance, call: 1-800-922-0354.
-
- Product Updates: The established policy is that AT&T does not provide
- upgrades for MS-DOS.
-
- Product Availability: MS-DOS 3.2 R1.0 is currently under Controlled
- Introduction status and is available only for the PC 6310.
-
-
-
- ENHANCED PERIPHERAL SUPPORT
-
- o 3.5 Inch, 720KB diskettes and diskette drives, both internal and
- external. An installable device driver, DRIVER.SYS, accommodates
- these and any other external drives.
-
- o Large hard disks, from 32MB to 128MB inclusive. This support is
- achieved by using the FDISK utility to create up to four partitions
- of a maximum 32MB each on a hard disk, one of which is a bootable
- MS-DOS partition and the remaining three being non-bootable DOS Data
- partitions.
-
- o RAMdisks, that is, portions of Random Access Memory used as disk
- drives, providing faster access to data stored there over data stored
- on hard disks or diskettes. An installable device driver,
- RAMDRIVE.SYS, when installed with the proper options, configures
- portions of one or more of the following types of memory as RAMdisks:
-
- - conventional 640KB memory,
-
- - expanded memory, from 256KB to 2MB, on the AT&T Enhanced Memory
- Expansion Board, or other boards which conform to the
- Lotus-Intel-Microsoft (Above Board) Expanded Memory
- Specification. (The AT&T Enhanced Memory Expansion Board does
- NOT work with the PC 6310.)
-
- - extended memory, a continuation of conventional memory from 1MB
- to 16MB, on the AT&T PC 6300 PLUS Only
-
- - upper extended memory, the top 384KB of memory on an AT&T PC 6300
- PLUS that is configured with 1MB or more of memory
-
- o AT&T 477 Color Graphics Printer. The GRAPHICS utility, when loaded
- into memory, enables a graphics display to be printed on this printer
- by pressing the SHIFT-PRT SC keys.
-
-
- NEW AUTOMATIC INSTALLATION PROCEDURE
-
- INSTLDOS.EXE is a prompt-driven utility that automatically
- partitions, formats, and installs MS-DOS 3.2 on previously unused
- hard disk systems, or upgrades an earlier version of MS-DOS already
- on hard disk systems to Version 3.2.
-
-
- NEW ON-LINE HELP FACILITY
-
- The HELP.EXE utility, in combination with about 100 Help text files,
- provides information on MS-DOS and Batch Processing commands and
- related MS-DOS topics, all at the MS-DOS prompt. Help Topic indices
- and informative text are displayed in color (on a color monitor) on
- attractive screens complete with prompts, status and error messages,
- and paging capabilities. Information on commands includes their
- purpose, syntax, options definitions, and sample usage. In addition,
- the Help Facility can be customized in terms of changing the names
- and contents of existing Help text files and adding new categories of
- Help Topics.
-
-
- ENHANCED MEDIA FLEXIBILITY
-
- AT&T's MS-DOS 3.2 includes major additions to the IOCTL system
- interface. The changes to the interface include these three new
- functions: Get/Set Device Parameters, Format Track on Logical
- Device, and Read/Write Track on Logical Drive. The introduction of
- these new IOCTL functions:
-
- o Provides a high degree of device independence
-
- o Decreases the amount of time needed by OEMs to write their
- machine dependent portions of MS-DOS
-
- o Allows OEMs to introduce new drivers without having to write
- a new device driver
-
-
- OTHER NEW UTILITIES
-
- APPEND - Sets a search path for data files.
- REPLACE - Updates previous versions of files in, or adds new files to a
- specified directory.
- TAG/EXEC/UNTAG - TAG specifies a set of files for subsequent use with
- EXEC, which performs a specified MS-DOS command on the tagged files.
- These files need not be related in terms of their filenames or the
- directories that contain them; thus, TAG is a more powerful tool than
- wildcard characters.
- UNTAG reverses the effect of TAG.
- XCOPY - Copies files, directories, and subdirectories, between unlike
- disk types if desired.
-
-
- OTHER ENHANCED UTILITIES
-
- FORMAT - Creates tracks and sectors, checks for bad sectors, and creates
- a directory on hard disk partitions and diskettes.
-
-
- OTHER UTILITIES MODIFIED TO IMPROVE IBM COMPATIBILITY
-
- COMMAND - Starts a new command processor.
- DISKCOMP - Compares the contents of two diskettes.
- DISKCOPY - Copies the contents of one diskette to another.
- LABEL - Creates, changes, or deletes the volume identification label on a
- disk.
- MODE - Sets the operating characteristics of the monitor, printer, and
- communications port.
-
-
- OTHER ENHANCEMENTS
-
- DRIVPARM - A new CONFIG.SYS command that allows overriding of parameters
- that MS-DOS assigns to a specified logical drive at boot time.
-
-
- IMPROVED DOCUMENTATION
-
- o New documentation to cover all new features and enhancements in
- MS-DOS 3.2
-
- o More complete, better organized, and more clearly written
- documentation in areas including: CONFIG.SYS, AUTOEXEC.BAT, hard
- disk organization, MS-DOS command reference, and batch processing.

-
- DOS 2.11 REL. 1.1
-
- There were several bugs in the original release of DOS
- 2.11R1.0 that were corrected in release 1.1........
-
- DOS is now capable of handling 2 hard disks of varying size.
- FORMAT can now format a disk larger than 10mb.
- FORMAT can now handle a hard disk with 2mb of bad sectors.
- GRAPHICS will now handle 640x400 resolution.
- FDISK is capable of recognizing 2 hard disks.
-
- COMP now executes when applications are resident in memory.
- PRINT now does background printing when applications begin.
- BIOS Clock Driver doesn't hang the system with IBM hardware.
-
-
-
- DOS 2.11 REL. 2.0
-
- The newest release of 2.11 includes all the fixes in REL.1.1
- plus some useful new commands......
-
- RAMDISK.DEV is a ramdisk utility to greatly increase speed
- of access.
- CHMOD is a UNIX like command for changing file attributes.
- SIZE not only shows file size, but totals size for all
- files.
- TREE has been modified for a much easier screen format.
- SHIP now provides for an easy hard disk park routine.
- BACKUP and RESTORE have been improved greatly.
-
- (Further documentation of these is in the DOS 3.1 manual)
-
-
-
-
- BACKUP
- The backup command will not work properly if programs are
- loaded in memory such as context switch and em4410.
-
- When indicating a / option using backup, you must leave a
- space between the drive indication and the / option. An
- example of the syntax is "backup C:*.* A: /s", if you don't
- put the space in, only the root directory will be backed up.
-
- The backup command will usually backup even copy-protected
- software (i.e. WORD), but not always, OVERHEAD EXPRESS
- can't be backed up successfully.
-
- You can use this chart and the CHKDSK command to determine
- approximately how many floppy disks you need to backup a
- hard disk. For a 20mb disk, just double the figures.
-
- Hardisk memory used Floppies needed
- 10mb...............................30
- 8.3mb..............................25
- 6.6mb..............................20
- 5mb................................15
- 3.3mb..............................10
- 1.6mb...............................5
-
-
-
- FORMAT
- Format /1 will format a disk to be single sided, but only
- 160k (DOS 2.11 REL. 1.1) losing 20k. The old DOS doesn't
- have this problem.
-
- In the DOS manual it states that /s has to be the last
- entry on the line when using format, this isn't true. The
- manual also says the /s copies two hidden sys files, this
- isn't true either, it copies IBMBIO.COM and IBMDOS.COM.
-
- FORMAT in DOS has a limit of 30 meg. To excede this
- requires a separate formatting utility and device
- driver software.
-
-
-
- MODE
- Undocumented in the manual is the /o option with mode.
- This will return the current status of all COM and LPT
- ports as well as the mode of the monitor.
-
- The instructions on page 5-59 of the DOS manual are
- wrong. When using MODE LPT1: x,y the only acceptable
- options are 80 and 132 for x, and 6 or 8 for y.
-
- When redirecting using the MODE command you must use
- a colon after LPT1. An example would be "mode lpt1:=com1".
-
- The 't' option with mode only works in conjunction
- with the 'r' and the 'l'. For example "mode,r,t".
-
-
-
- RECOVER
- When you use the RECOVER command, any file recovered
- is renamed FILExxxx (starting at FILE0001). If you did
- this without naming a particular file (i.e. RECOVER D:)
- all files will be renamed, if you didn't backup or copy
- the files previously, you will have a near impossible
- task of renaming (using) the files, as only ascii
- files will be readable.
-
-
-
- RESTORE
- Subdirectories previously backed up (within the
- subdirectory) must first be created before using RESTORE
- (RESTORE will not create the subdirectory). Otherwise,
- RESTORE will prompt for all of the disks, but no files
- will be restored. Note, however, that RESTORE will
- create subdirectories and restore files to a virgin
- (nothing on it) hard disk.
-
-
-
- SORT
- The maximum file size that can be sorted is 63k.
- The proper syntax for the SORT command is ............
- "SORT[/R][+n] <file >file1", the default for column no.
- is 1. There are only 2 spaces in the command line,
- before <file, and after <file.
-
-
-
- TREE
- If you use the /F option with a printer toggled on,
- the individual file names will not print out on the
- printer. You would have to redirect the output to a
- file, and then print the file out. However, when doing
- this, all file names are concatenated together,
- removing tabs, carriage returns, and line feeds.
-
-
-
- FORMAT.COM
- The following modification will cause the FORMAT
- command to assume the A: drive should you forget and
- leave the drive specification off. It allows use of
- /o /v /s options.
- C>debug format.com
- -E174 B4 09 B0 00
- -w
- Writing 19EC bytes
- -q
- C>
-
-
-
- DIRECTORIES
- When formatting in DOS, the device driver used sets a
- maximum number of directory entries (root only)
- as follows......
-
- FLOPPY ss............64 ds...........112
- HARD 10 meg.......512 20 meg......1024
-
-
-
-
- ANSI.SYS
- To make full use of the PROMPT command, you must have
- ansi.sys in your config.sys file (device=ansi.sys) and
- both must be in the root (boot) directory (or specify
- full path name).
-
-
-
- PROMPT
- The example of the PROMPT command on page 5-69 is
- incorrect. Both brackets should be right facing ([).
- Also, this command will not give the required results,
- after one full screen, the entire display will be
- inverse video, not just the cursor.
-
-
-
- KEY PROGRAMMING
- An example of programming keys with the PROMPT command
- is... "PROMPT $E[0;59;"dir";13p". The "$E" defines
- that what is to follow is to be accepted literally, the
- "[" starts the beginning of the code, the "0" is a
- necessary null variable (this position is usually
- defined for cursor positioning in other operations),
- the "59" is the keyboard scan code for the F1 key
- (59-68=F1-F10), "dir" in quotes is the string that you
- insert for execution, and "13p" is the decimal value
- for a carriage return to execute the string. Note that
- this example will erase any prompt that you are
- currently using. If keys are reprogrammed using PROMPT,
- the reprogrammed values may be passed on to programs,
- instead of the default keyboard scan codes.
-
-
-
- USE OF $p IN PROMPT
- Used to display pathname of current directory as part
- of your prompt. If the A drive is selected as your
- default drive and the diskette is removed, any attempt
- to execute DOS commands (resident or otherwise)
- results in an "abort, retry, ignore" error message. The
- system then requires a disk in the A drive to continue.
- The reason is the $p causes a search for the default
- drive pathname each time it writes information to the
- prompt. Omitting the$$p from the prompt eliminates this
- problem.

-
- Understanding the Enhanced Memory Card
- ======================================
-
- Definitions: Non-paged Memory = Extended Memory
- Paged Memory = Expanded Memory
-
- Note: Expanded Memory (Paged) may be converted to Extended Memory by
- using the AEX utility but Extended Memory can not be converted to
- Expanded Memory.
-
- Setting Switches on Extended Memory Card:
-
- Start by setting SW2 positions 1-4. Each Extended memory card must
- have a unique base address. (Unique meaning different from any other
- Extended Memory Card or any other peripheral in the system.)
-
-
- BASE I/O ADDRESS SW2-1 SW2-2 SW2-3 SW2-4
- ====================================================

- 02B8 OFF ON OFF OFF
- 02C8 OFF OFF ON ON
- 02D8 OFF OFF ON OFF
- 02E8 OFF OFF OFF ON
- 02F8 OFF OFF OFF OFF
-
- Setting SW2:
-
- SW2 positions 5-8 are for specifying the amount of non-paged memory
- on the Extended Memory Card that you are installing. These switch
- settings are board independant and only affect the RAM on that board. If
- all of the RAM on the Extended Memory card is to be set up as paged,
- these four switch positions will be ignored. The amount of paged memory
- on the Extended Memory Card equals the total amount of memory on card
- minus the amount of non-paged memory.
-
- Amount of Non-Paged
- Memory on board SW2-5 SW2-6 SW2-7 SW2-8

- 2048K OFF OFF OFF OFF 2.0 MG
-
- Setting SW1:
-
- If none of the memory on a given Enhanced Memory Board is to be
- set up as non-paged set all switches on SW1 OFF. Switch position SW1
- must be set to show the amount of non-paged memory below the board
- being installed. Note: If 1 Mb of ram reside on the motherboard of a
- PC6300+, only 640K of this ram is considered non-paged. The remaining
- 384K is addressed at the very top of memory and therefore is not below
- the board that is being installed. SW1-8 is the parity enable switch.
- This should always be on unless none of the ram on board will be non-
- paged.

-
- Using Enhanced Memory Card in 6300:
- The Enhanced Memory Card comes set up for use with the 6300+. If
- if is to be used with the 6300 you must rotate the jumper block
- located next to the mounting bracket 180 degrees. The jumper block has
- a dot on it in location of pin 1. This dot should be down (at pin 9)
- for the 6300 and up (at pin 1) for the 6300+.
-
- Using Enhanced Memory Card Ram as conventional memory.
- To us the RAM on the Enhanced Memory Card as conventional memory
- you need to set up the Enhanced Memory Card to have non-paged memory of
- at least the amount of conventional memory to be added. Change the
- switch settings on the motherboard to reflect the added memory.
- Remember, all switches on the Extended Memory Card are relative to
- that card so if you have 256K on the motherboard and are using 384K on
- the Enhanced Memory Card to expand conventional memory, you would set
- SW1 to show 256K ram below the Extended Memory Card.
-
- Examples: 256K Motherboard. 1MB on Enhanced Memory Card. All non-paged.
- 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8
- SW1- ON ON ON ON ON OFF ON ON SW2-ON ON ON OFF ON OFF OFF OFF
-
- 256K Motherboard. 384K Non-paged, 640K paged.
- 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8
- SW1- ON ON ON ON ON OFF ON ON SW2-ON ON ON OFF ON ON OFF ON
-
- Using the SuperPak software:
- You must enter in your config.sys DEVICE = AEMM.SYS in order for
- the PC to address the paged memory. This makes the paged memory
- available for LOTUS or SYMPHONY types of programs that can use above
- memory. The Superpak utilities can use either conventional memory or
- Extended Memory. You can not use memory set up as non-paged memory (by
- the switch settings) for these utilities. You must use the DEVICE = AEX
- (nnn) command where (nnn) is at least the sum of the memory used by the
- Superpak programs.
-
- Examples:
- SUPERSPL LPT1:/EXTM Will use the remainder of extended memory
- for a print spooler for LPT1.
-
- SUPERSPL LPT1:/M=24 Will assign 24K of extended memory
- for a print spooler for LPT1.
-
- SUPERDRV C:/EXTM Will assign a 360K Ram Drive in
- extended
- memory assigned to logical drive C:.
-
- SUPERDRV D: Will assign a 360K Ram Drive of
- conventional memory assigned to
- logical drive D:.
-
- DEVICE = RAMDISK.DEV 512 512 64 /E
- (In config.sys after DEVICE = AEX nnn command.)
-
- Will assign a 512K ramdisk with 512
- byte sector size and 64 Directory
- entries. All of these parameters
- must be in multiples of 16 or they
- will round to the next multiple of
- 16 value. The /E option puts the
- ramdisk in extended memory. To
- create multiple ramdisks, you would
- use multiple DEVICE=RAMDISK state-
- ments in your config.sys.
-
- For further examples, see the READ.ME file on the SUPERPAK
- utilities diskette or the SUPERPAK manual that comes with the Enhanced
- Memory Board.
- Note: The /E option in the examples is the same as the /EXTM
- switch. Once the /E option is enabled, it will be assumed for all
- following commands unless the /DEXTM switch is used.

-
- Adding a 3.5" MFDU to a PC6300:
-
- The support for the 3.5" MFDU is built into AT&T MS-DOS 3.2. The driver
- DRIVPARM must be installed into the CONFIG.SYS file of the drive used to
- boot the computer. The command line is:
- DRIVPARM=/d:02 /C
- This will set the B drive to 720K format. No jumpers have to be set on the
- motherboard. See Appendix E of the AT&T MS-DOS Users Guide.
-
- PC6300+:
-
- This is the same as for the PC6300, but will only work if the PC6300+ is
- running PURE MS-DOS. UNIX does not recognize 3.5" drives, nor does
- Simul-Task DOS.
-
- PC6310/PC6312:
-
- With these PC's, simply run SETUP to configure CMOS setting the B drive to
- 720K. There is no need to install the driver in CONFIG.SYS.

-
- There seems to be a number of people calling in to
- report slow clocks. There is a jumper plug
- located at C-9 on the motherboard. Make sure this
- is in place. If it is not there, charging the
- battery won't help. Provided it is there, the
- clock battery requires a charge of approximately
- 72 hours before it will hold time. We usually
- suggest turning the intensity down during this
- time period, if the machine is not being used.

-
- USING TWO FLOPPIES OF DIFFERENT MAKES
- We currently have three different types of disk drives
-
- Toshiba - door that flips down and can be ordered,
-
- Toshiba - latch that turns clockwise (centered) (is a
- production model) and can't be ordered. If
- found defective replace with an Olivetti
- drive for cosmetic reasons.
-
- Olivetti - latch that turns clockwise (offset to left).
-
- These drives have their data connector in different
- places making it impossible to use the one MFD cable to
- connect them unless the machine is equipped with the
- 100mm (new) cable as opposed to the standard 50mm (old)
- cable. This change was in affect approximately 1/1/85.
- You should determine which cable you have before
- ordering a different drive replacement. Of course a
- like replacement won't matter.
-
-
-
- MAX NUMBER OF DRIVES
- Our machine can support a maximum of TWO MFDUs. Dip
- Switches for three and four drives are only useful for
- Ram Disks.
-
-
-
- DIP SWITCHES - DPSW-1 Location 7W on motherboard
-
- # of drives | SW-7 | SW-8
- ------------------------------
- 1 | 1 | 1
- 2 | 0 | 1
- 3 | 1 | 0
- 4 | 0 | 0
-
- NOTE 3 AND 4 ARE ONLY FOR RAM DISKS
-
-
-
- 96-TPI FLOPPY DRIVES
-
- MS-DOS does not have the power to use this feature even
- though there is a dip switch for it. That switch is
- meant for future use and we do not support the 96-tpi
- feature.

- KEYBOARD CONTAMINATION
- Many calls are received regarding a keyboard key or keys
- not working properly. This is usually due to some foreign
- material lodged between the contact on the circuit card
- and the carbon contact on the bottom of the key plunger.
- Generally, these problems can be resolved by the customer.
-
- 1. Remove the key cap by gently prying under the
- edge of it.
- 2. Release the two catches that hold the key in place.
- 3. At this point the key mechanism will come out in
- one piece.
- 4. Clean both the bottom contact of the key and the
- contact on the circuit card. Use some type of swab
- and a cleaner if possible. Be careful not to
- introduce new contamination.
- 5. Reinsert the key and replace the keycap.
- 6. If not successful, replace the keyboard.
-
-
-
- LOOSE SCREWS
- There are approximately a dozen screws that hold the bottom
- plate of the keyboard on (metal plate). If one or more come
- loose it will cause keys to not make proper contact with the
- circuit card, getting no response. This is usually indicated
- when several keys in the same area don't work. Open the
- keyboard and tighten all of the screws.

- Parallel Loopback Plug Pin-out
-
- In the PC6300 Service Manual, it lists the pin-outs for the parallel
- loopback plug. Using the pin-outs provided, the plug will not yield
- positive results, even if the parallel port works with any printer
- imaginable. The following pin-outs will work correctly:
-
- 1 <========> 13
- 2 <========> 15
- 10 <========> 16
- 11 <========> 17
- 12 <========> 14
