  SHOW.EXE is a program that shows just about all about the running DOS and
  hardware. It is just like peeking around in your PC using a small
  multi-point small flashlight...

  Features include :
      - HELP for all available flashlights
      - Hardware check
          - CPU range 8086, 8088, NEC V[23]0, 80186, 80188, 80286, 80386.
          - NDP range 8087, 80287, 80387
          - Speed calculation (CPU/NDP)
          - Hardware (disks/IO-ports) recognized by standard BIOS
          - Videocard range CGA, Hercules, EGA, (VGA)
          - Extended Memory sizes (AT and up only)
          - Expanded Memory (LIM) sizes

      - DOS internals
          - System information
            device chain information, last logical drive, DOS buffers etc.
          - Current directory paths including some obscure drive status and ID
          - Drive parameter blocks
          - Memory control blocks and their usage by all TSR programs and
            their environment(s)
          - Memory usage (memory map) (TSR/DOS) (extended with PSP-info)
            and their interrupt usage
          - BUFFERS usage (CONFIG.SYS BUFFERS=), buffer status (i.e. not flushed)
            and to which drive/sector combination it is set
          - FILE usage (CONFIG.SYS FILES=) and their access rights. The handle
            part in this case is something hidden to me...
          - Device chain list including attribute bits
          - Detailed disk information (FAT-Space etc).
      - BIOS
          - Interrupt vector contents (text info about interrupt usage)
