   MEMORY MAP
   This report lists all DOS Memory Control Blocks along with their
   address, type (data, program, environment etc.) & owner. Use this to
   determine what TSRs have been loaded before QAPlus.

   INTERRUPT
   Use this report to properly configure any boards you are adding and
   avoid any IRQ conflicts without having to check each installed board
   to figure out how it is configured.  The Interrupt Screen shows
   three areas of information:

   SYSTEM SOFTWARE shows the ROM BIOS vendor and DOS Version you are
   using.

   DMA CHANNEL usage shows how the Direct Memory Access channels are
   configured.

   INTERRUPT ASSIGNMENTS indicate how the Interrupt Requests (IRQs) are
   configured.  QAPlus may be unable to identify interrupts used on
   certain non-standard expansion boards.

   At the end of this report, QAPlus will loop for approximately two
   seconds, looking for any interrupts which occur without apparent
   reason.  Interrupts of this nature are called stray or spurious 
   interrupts.  If any stray interrupt activity is detected, 'STRAY' 
   will be listed as using a particular IRQ line.  Any other devices 
   listed along with 'STRAY' MAY be incorrectly identified.  This is due 
   to the fact that a 'STRAY' interrupt may have occurred when QAPlus 
   was testing a particular device, causing that device to be 
   incorrectly identified.
   
   HARDWARE
   The Hardware screen shows the configuration of standard hardware
   that is in use by your computer including the type of CPU and
   numeric co-processor (if any), the amount and type of memory, the
   video configuration, hard drives (note: If you have a large hard
   drive that has been partioned into several logical drives, this
   partitioning will not show.  Only separate physical hard disk drives
   will be shown), floppy disk drives, a clock / calendar, parallel
   (LPT) and serial (COM) ports and a game port (Joystick) and/or mouse
   will be displayed.

   DEVICE DRIVERS
   Device drivers are software that permits DOS to communicate with
   different types of hardware such as disk drives.  The information
   presented is helpful to a hardware technician in diagnosing possible
   conflicts between devices.

   ENVIRONMENT
   The environment displays information used by DOS and other programs
   to define the environment they use.  Some of the more obvious
   environment information items are COMSPEC which tells DOS where to
   find COMMAND.COM and PATH, which tells DOS where to search for
   programs.

   DISK PERFORMANCE
   Three aspects of disk performance are shown. Track-to-track and
   average seek times are determined through low level calls to the
   BIOS.  Lower numbers represent higher performance.  DOS File
   Transfer measures the time to write a file using DOS.  The file size
   as well as the record size used are shown below the transfer window.
   Higher numbers represent higher performance.  A disk cache program
   will substantially increase the DOS File Transfer performance.  Note
   that this does not measure the raw tranfer speed of the disk
   subsystem.  Rather, it is an indication of overall DOS file
   throughput.
   
   SYSTEM PERFORMANCE
   System Performance, through 11 different tests measures the
   performance of the CPU (Dhrystones), Video and Math processing
   (Whetstones).  The CPU type (8088, 80286, 80386 or 80486) 
   is shown along with its clock speed in MHz. 
   
   If a Numeric co-processor is present, it is identified (8087, 80287, 
   or 80387).  A bargraph comparing the speed of the CPU with other 
   popular computers is displayed.
