Command: tdsk

  TDSK creates a RAM disk. Part of memory is set aside to act like a
  disk drive. Because memory is much faster than a real disk drive,
  RAM disks are very fast, but anything stored on them will be lost when
  the machine is restarted or switched off. TDSK supports XMS, EMS and
  conventional memory.

Syntax:

  device=tdsk.exe size [[s_sector [files [s_cluster]]]] [/E] [/A|X] [/C]
                       [/M]

Options:

  size    the size of the RAM disk, from 8 to 65534 (in Kilobytes).
  [[s_sector [files [s_cluster]]]]
          Advanced. The size of the sectors, root and clusters
          on the disk.
          Valid values for sector are 32,64,128,256,512,1024,2048.
          Files (in the root direcotry) can be from 1 to 65534.
          Clusters can vary from 1 to 255 (some systems are restricted
          to 1,2,4,8,16,32,64,128)
  /E      Forces the use of XMS memory.
  /A      Specifies the use of EMS memory.
  /X      Specifies the use of EMS memory.
  /C      Forces use of conventional memory (not ideal, so it is
          generally only recommended for systems without XMS/EMS or if
          you are having problems with XMS/EMS memory.)
  /I:nnn  nnn=country code. This will show the help in another language.
  /M      Switches the screen output from color to monochrome(redirect-
          able) while in CONFIG.SYS monochrome will be used by default.
  /B      avoids to load TURBODSK if there is at least one hard disk
          available on the system.
  /F      selects the number of FAT copies (1 by default) up to a maxi-
          mum of 2.
  /H      Shows the help.
  /?      Shows the help.

Comments:

  Size must be in the range 8 - 65534 KB; valid sectors are from 32 to
  2048 Bytes (in powers f 2), though some DOS versions support 128, 256
  and 512 Bytes only. Files of root may be 1 to 65534 and sectors by
  cluster can vary from 1 to 255 (some systems need a power of 2). Only
  the size is necessary.
  Turbodsk defaults to XMS or EMS. 
  After installing TURBODSK in CONFIG.SYS it can be run from AUTOEXEC.BAT
  or the prompt in order to vary the drive size (amount of memory used); 
  this also erases the drive's contents. A size 0 can be used to
  completely free the memory occupied by the drive: When using
  conventional memory it is useful to cancel a drive BEFORE resizing.
  When more than one TURBODSK is installed, they can be identified by
  additionally giving the drive letter.
  By default, tdsk tries to use XMS or EMS, before trying to use 
  conventional memory. Most modern computers have XMS.
  Why use a RAM disk?
  Many programs create temporary files, which will be stored in a
  temporary directory specified by an environment variable:
   set temp=c:\temp
  Temporary files are deleted when a program exits anyway. So one of the 
  main uses of RAM disks is to hold this temporary directory. This 
  increases such programs' performance.
  TDSK has the following EXITCODES (ERRORLEVEL):
      0: Disk not defined
    255: Driver not installed from CONFIG.SYS
    254: Incorrect drive letter specified
    253: Attempt to define a drive from within a multitasking
         environment such Windows, DOSSHELL, TASKMAX/TASKMGR, etc.
    252: Syntax error
  Other values below  128 are related to  the  handle  used  in  both
  the Extended or the Expanded memory.

Examples:

  IN CONFIG.SYS/FDCONFIG.SYS:
    device(high)=c:\fdos\bin\tdsk.exe 8096 
                   (creates 8096 KB RAM disk)
    tdsk.exe 0     resizes the ramdisk to 0 Byte size
                   (deletes all files)
    tdsk.exe 2048  resizes the ramdisk to 2048 KB size
                   (deletes all files)
