- SysInfo:
-
- Memory Map: ( see release.not )
-
- 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: ( Manual Page 30 )
-
- 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: ( Manual Page 32 )
-
- 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 Driver: ( Manual Page 38 )
-
- 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: ( Manual Page 40 )
-
- 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: ( Manual Page 41 )
-
- 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: ( Manual Page 44 )
-
- System Performance, through 11 different tests measures the
- performance of the CPU (Dhrystones), Video and Math processing
- (Whetstones). The CPU type (8088, 80286 or 80386) 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.
