                       SYSINFO 


1ST MB MEMORY MAP 
   
   This screen provides information specifically on the 
   first megabyte of memory addresses in your computer 
   system.  It provides information showing DOS (640K) 
   and Upper Memory blocks (640-1024K), including the 
   addresses for Video RAM, System ROM, EMS page frames, 
   Expansion ROM, and Used/Unused high memory.  QEMM386 
   High RAM is now identified. 
   
   
DOS MEMORY MAP 
   
   This report lists all DOS Memory Control Blocks along 
   with their address, type (data, program, environment 
   etc.) & owner.  It shows which DOS programs are 
   loaded in the lower 640K or memory as well as the 
   upper memory blocks.  Use this to determine which 
   TSRs have been loaded before QAPlus.     


INTERRUPT INFORMATION 
   
   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 INFORMATION 
   
   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 drive(s) (note: only physical 
   drives and their sizes are shown, not partitions.  
   Drives compressed with MS-DOS 6.0 Double Space are 
   shown with a "DBL" indication), Drive(s) local (NET) 
   (note: logical drive partitions are shown), floppy 
   disk drives, a clock / calendar, parallel (LPT) and 
   serial (COM) ports, a game port (Joystick), mouse, 
   sound card and scanner will be displayed. 


DEVICE DRIVER INFORMATION 
   
   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 INFORMATION 
   
   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 hardware.  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 
   transfer 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 bar graph 
   comparing the speed of the CPU with other popular 
   computers is displayed.
