- *** Accessing TransDisk with a DOS Drive Letter
-
- Accessing TransDisk requires loading the TransDisk device driver (TRANSD.SYS)
- which assigns a DOS drive letter. To do this, you need to perform one of the
- following:
-
- 1. Permanent Installation --
- TD utility allows normal installation of the TransDisk software onto the
- internal hard drive. It makes changes to the CONFIG.SYS file. A reboot
- is required to load the device driver.
-
- Syntax: TD
-
- 2. Dynamic Loading --
- TDGO command allows loading the device driver dynamically without first
- installing the software via TD. It does NOT change any of the host system
- setup. No reboot is required.
-
- Syntax: TDGO [timing]
-
- timing timing adjustment for device driver to match parallel port
- characteristics. Range: 0 - 99; Default = auto-detect.
-
- See following sections for detail on timing adjustment.
-
- --------------------------------------------------------------------
-
- *** TRANSD.SYS Options
-
- Usage:
-
- In config.sys
-
- DEVICE=C:\TRANSDSK\TRANSD.SYS [/T:<t>] [/S:<s>]
-
- Description:
-
- /T option allows manual setting of the timing between the device
- driver and the printer port. When /T option is not specified (default),
- the device driver will AUTOMATICALLY adjust its timing to accomodate
- the hardware at hand while maintaining the optimal performance.
- When /T option is specified, AUTO-TIMING mode is disabled, and
- <t> indicates the MANUAL-TIMING parameter. The larger the value of <t> is,
- the slower the system becomes. In particular, when <t> is set to 0, the
- system will run at full speed.
-
- /S option allows you to change the timeout value associated with
- the STANDBY mode operation of the TransDisk 2000 series. When /S option
- is not specified (default), a TransDisk 2000 unit will enter STANDBY mode
- (Hard drive motor not spinning, to save battery power) when it is not
- accessed in 5 min. Once it receives a command, it will spin up again
- and execute the command.
- When /S option is specified, <s> indicates a timeout value in
- seconds. If the unit is not accessed in <s> seconds, it will enter the
- STANDBY mode. If <s> is not a multiple of 5, it will be rounded up to
- the next multiple of 5. The minimum value of <s> is 60 (1 min.). The
- maximum is about 1200 (20 min.). If <s> is set to 0, the STANDBY mode
- is disabled.
- TransDisk 3000 series ignore /S option, and disable STANDBY
- mode operation.
-
- Example:
-
- DEVICE=C:\TRANSDSK\TRANSD.SYS
- Set AUTO-TIMING mode and STANDBY-TIMEOUT to 5 min., this is default setting.
-
- DEVICE=C:\TRANSDSK\TRANSD.SYS /T:1 /S:180
- Set MANUAL-TIMING mode to 1 and STANDBY-TIMEOUT to 3 min.
-
- DEVICE=C:\TRANSDSK\TRANSD.SYS /T:0 /S:0
- Set MANUAL-TIMING mode to 0 and disable STANDBY-TIMEOUT.

- *** Note on Printer Port Compatibility (1)
-
- If you cannot access TransDisk and you have already followed the
- troubleshooting instruction in the User's Guide, it is most likely
- that your printer port may not be fully IBM compatible. In this case,
- Adjust the timing by using /T option mentioned above and reboot the system.
- Also see the note below.
-
- ____________________________________________________________________
-
- *** Note on Printer Port Compatibility (2)
-
- If you are using IBM PS/2 (or similar) machines which has DMA capability
- on the printer port, e.g., PS/2 models 56, 57, 76, 77 and 90XP, you MUST
- disable the "DMA Arbitration Level" of the printer port to use TransCD.
-
- In order to do so, you can enter configuration (CMOS) setup mode at
- the system boot time. On PS/2 model 56, enter Ctl+Alt+Ins when cursor
- moves from upper left corner to right upper corner at system boot.
- Please refer to PS/2 User's Handbook for additional information.
-

-
- *** Dynamic Driver Loader (enhanced in ver. 2.20)
-
- Instead of using DEVICE entry to load the TransDisk driver in CONFIG.SYS,
- DLD.COM allows a user to load TransDisk driver at DOS prompt.
- DLD.COM works on MS DOS 3.x, 4.x, 5.x, and 6.x. It may or may not work on
- other DOS operating systems.
-
- Syntax:
- DLD [-drive_letter] driver_file [driver_options]
-
- Example:
- DLD C:\TRANSDSK\TRANSD.SYS
- TransDisk will be assigned the NEXT available drive letter on the system.
-
- Example:
- DLD -P C:\TRANSDSK\TRANSD.SYS
- TransDisk will come up as P: drive. Make sure LASTDRIVE in CONFIG.SYS
- is greater than the drive letter specified.
-
- ____________________________________________________________________
-
- *** Additional Utility, TDPATH.EXE
-
- Included on this package diskette is the utility TDPATH.EXE.
- TDPATH.EXE allows you to customize your PATH with directories
- available on your TransDisk. To invoke TDPATH.EXE, type
- tdpath (if tdpath.exe is not in your execution PATH, use
- full path) at the command prompt or include it in your AUTOEXEC.BAT.
-
- When invoked, TDPATH.EXE searches TDPATH.ADD the root directory on
- all partitions including TransDisk and non-TrnasDisk partitions for
- the file TDPATH.ADD. If a TDPATH.ADD is found, TDPATH.EXE will
- extend your PATH based on the contents of TDPATH.ADD. TDPATH.EXE
- exits with error if there is no TransDisk attached to your system.
-
- The format of TDPATH.ADD is as follows:
-
- 1:\lbin;2:\uti;1:\net10
-
- Leading # and rem are considered remark lines and ignored.
-
- Using above example and if current TransDisk starts as F:,
- after TDPATH excuted, your PATH becomes
-
- PATH=your_old_path;F:\lbin;G:\uti;F:\net10
-
- --------------------------------------------------------------------
-
- *** MANUAL INSTALLATION AND UN-INSTALLATION
-
- To install TransDisk software manually follows below.
-
- 1. copy TransDisk software into your boot drive,
- 2. in config.sys, add driver statement as
- DEVICE=your_drive:\your_dir\TRANSD.SYS
-
- To un-install, remove the driver statement from config.sys and/or
- remove TransDisk software from boot drive.

- *** How to use TransDisk on a OS/2 system
-
- Before an OS/2 native driver is available for TransDisk, the following
- procedure can be used to access TransDIsk on a DOS session under OS/2.
- Thanks to Mr. Doug Azzarito of IBM, an excellent technical support,
- accessing TransDisk under OS/2 is now possible.
-
- The following procedure describes how to access the TransDisk from OS/2
- by using a "specific DOS session." This is a feature in OS/2 that allows
- you to boot a session of "real" DOS mode while running OS/2. To set this
- up, do the following:
-
- * Hardware:
- If you are using non-PS/2 machine, no hardware setup is necessary.
- If you are using PS/2 (or similar) machines which has DMA capability
- on the printer port, e.g., PS/2 model 56, you MUST disable the DMA
- of the printer port to use TransDisk.
-
- In order to do so, you can enter configuration (CMOS) setup mode at
- the system boot time. On PS/2 model 56, enter Ctl+Alt+Ins when cursor
- moves from upper left corner to right upper corner at system boot.
- Please refer to PS/2 User's Handbook for additional information.
-
- * Software:
- (1) Create a bootable DOS diskette that will load the TransDisk driver.
- Boot from this diskette to make sure everything works properly.
- (2) Boot OS/2, and insert the bootable DOS disk in drive A:
- (3) Copy the file \OS2\MDOS\FSFILTER.SYS to A:
- (4) Add the line: DEVICE=FSFILTER.SYS as the first line in the CONFIG.SYS
- on the bootable DOS diskette.
- (5) Open the COMMAND PROMPTS folder (inside the OS/2 SYSTEM folder).
- you will see a "DOS FROM DRIVER A:" object. Start that object, which
- will boot the DOS disk in drive A:.
-
- From this DOS session, you will have access to the TransDisk. No other
- session will see the TransDisk, and all printing from other sessions will
- be held in the spooler until the DOS session is closed.
-
- The VMDISK command can make an "image" of this boot floppy, so you can start
- a TransDisk session without inserting the floppy. Type HELP VMDISK from
- an OS/2 command prompt for details.
-
- * Caveat:
-
- Due to multitasking environment of OS/2, TransDisk performance on this
- DOS session is far below that in actual DOS environment.

- *** Password Protection (new in ver. 2.20)
-
- Password protection is a security feature that prevents an unauthorized access
- to the TransDisk. Normally the TransDisk is shipped without the password. In
- order to use the password feature, the user needs to run TD.EXE version 2.20
- or higher and use the option 14. The password can be up to 8 characters of
- any combination. Once the password is set and the system rebooted, subsequent
- usage of that TransDisk requires password to gain access. This feature
- requires a matching version of the driver (TRANSD.SYS) to work as specified.
-
- ____________________________________________________________________________
-
- *** Read-Only Protection (new in ver. 2.20)
-
- Read-only protection is a safety feature that prevents writing to the
- TransDisk while still allowing read access to it. TransDisk acts just like
- a read-only device much the same way as the write-protected floppy diskette.
- The transDisk in read-only mode can be used as a distribution medium
- especially in an environment where virus infection is a problem. In order
- to use the read-only feature, the user needs to run TD.EXE version 2.20 or
- higher and use option 7. The read-only mode can be turned on or off and
- takes effect the next time the system is rebooted. This feature requires
- a matching version of the driver (TRANSD.SYS) to work as specified.
