Shown here are standard  features most often used to describe a particular  system: processor (CPU), manufacturer, video  adapter type, number and type of I/O ports and  memory capacity.  This screen tells you if you  have a numeric coprocessor.  It tells you the  developer and date of the BIOS firmware.      This information is basic to any discussion of a  computer system.  It's what you would tell a  friend if you were describing your system.   Technical support personnel often need this  information to resolve a problem.    ÿÿThe ÿ úSystem CONFIGÿ ø screen shows the contents of  your CONFIG.SYS file.  Statements in this file  extend your operating system in several ways.   This file may load device drivers to support  additional hardware.  It is also used to increase  the memory DOS uses to support disk and file  access.      A look at this file tells you how your system may  differ from another system.  It serves to remind  you of the your system's special needs and  capabilities.  Many commands in CONFIG.SYS affect  memory usage.  A periodic review of this file  gives you an opportunity to understand or fine  tune your memory requirements. ÿÿThe ÿ úSystem AUTOEXEC ÿ øscreen shows the contents of  your AUTOEXEC.BAT file.  DOS executes statements  in this file every time you start up your  computer.  These statements customize a PC in  several ways. You can specify search paths,  set up a helpful prompt and load useful  Terminate and Stay Resident (TSR) programs.  A periodic review of this screen serves to remind  you how you have customized your system in the  past.  You may find obsolete utilities.  Also, the TSR's you find here may be the source of problems with newly installed programs. ÿÿThe ÿ úSystem Video Display Adapterÿ ø screen shows  details about the display adapter(s) you have  installed.  The type of adapter is given in  industry standard terms (i.e. CGA, VGA).  The  area(s) of adapter memory used are shown, both  ROM firmware and display memory.  If the ROM  contains a manufacturer's signature, it is  displayed.  If you have two display adapters,  both are shown.  With this information you know the capabilities  of your display adapter(s).  Check this screen  to confirm graphics capability, or to  verify  that the system sees two adapters if two are  installed or to determine resolution or color  features based on the video type. ÿÿThe ÿ úSystem Disk Adaptersÿ ø screen identifies the  disk drives installed in your system.  It shows  the number of floppy and hard disk units.  For  each of these it gives the drive characteristics,  type and formatted capacity in tabular form.  This display is useful to confirm a successful  installation of new equipment, to easily and  quickly determine the presence of a high density  floppy, or multiple hard drives installed within  the case. ÿÿThe ÿ úSystem Serial / Parallel Adaptersÿ ø screen  shows the industry standard Port I/O adapters  present in your system.  The display shows the  number and Port Address of each serial adapter  and the number and Port Address of each parallel  adapter detected.  Standard signals and their  current state are shown beside each device in  tabular form.  This information may be used to confirm the  presence of such devices and to avoid clashes if  you add devices using industry standard ports.   Experienced users may find the state of the  signals informative.  Less involved users can  relay this information to others. ÿÿThis ÿ úSystem Adapterÿ ø screen shows you the  adapters installed on your microchannel machine  according to information found in the Adapter  Description Library (ADL) file.  The information  is presented in tabular form, showing: slot  number, device type number in hexadecimal,   identifying name, and the area of memory used by  the adapter.   This screen presents a convenient display of the  your installed adapter equipment for problem  solving, equipment inventory purposes and memory  usage determination.   ÿÿThe ÿ úSystem CMOSÿ ø screen shows the information  in the CMOS memory of AT class and later PCs.   The display is like your system's Setup program.   CMOS memory is preserved by battery power when  your machine is turned off.  When you have to  change your batteries, information here is lost.   You can use this screen to capture CMOS settings  before you change the battery.  You can compare  information on this screen with other screens  reporting the same type of information.  Other  methods of equipment determination may show   anomalies which show up in the way your programs  behave.  You should try to resolve such  differences.   ÿÿThis ÿ úSystem CMOSÿ ø screen shows the information  in the CMOS memory of AT class and later PCs.   The display shows each byte of the CMOS memory, gives a brief description of its meaning and  shows the current value of the byte.  Locations and values are shown in hexadecimal, except for the date and time bytes; these are in decimal.  This screen offers convenient access to the  contents of your CMOS memory.  Viewing this  information on different machines may reveal how different manufacturers use CMOS. ÿÿThe ÿ úFirst Meg Overviewÿ ø screen(s) show memory  areas in the first megabyte of address space.  The summary view is partitioned at the  conventional memory boundary.  Memory above that  is usually devoted for hardware adapter use and  BIOS ROM but may also have room for programs.    The information is presented in tabular form,  giving: the area used in hexadecimal, its size in  K (K=1024 bytes), and how or by what it is being  used.     The information on these screens enable you to  analyze your memory usage, to identify areas used  but no longer needed, and to target opportunities  for making better use of memory. ÿÿThe ÿ úFirst Meg Programs ÿ øscreen(s) show a  breakdown of the memory areas used in the first  megabyte of address space on your system.  Con-   ventional memory is always shown.  If you have a  memory manager, the area between conventional  memory and the first megabyte boundary, which is  nominally devoted for hardware adapter use and  BIOS ROM, is also shown.  The information is  presented in tabular form, giving: the area used  in hexadecimal, its size in K (K=1024 bytes), and  the program owning the memory (or how it is used).     The information on these screens enable you to  analyze your memory usage further, focusing on  programs and their memory usage.  Opportunities  for fine-tuning memory use may show up here.   ÿÿThe ÿ úFirst Meg Interrupts ÿ øscreens present two   detailed views of your PC's interrupt vectors.  The first set of screens lists the programs  providing interrupt services followed by the  interrupt vector number(s) they service.  The  second set of screens list the interrupts by  their number, giving also the name or purpose of  the interrupt and the address and name of the  program providing the service.   Experienced users may find these screens helpful  in determining conflicts among programs trying to  provide interrupt services, during debug sessions  for locating the routines, for finding a 'safe'  interrupt to use or simply as a quick reference  to the interrupt services defined. ÿÿThe ÿ úFirst Meg BIOS Dataÿ ø screens show the data  area in RAM devoted for use by the ROM BIOS.   Many application programs reference, and some  change, the information contained in this  memory area.  The display consists of several  screens showing the offset within the BIOS data  area, the name or purpose of the data, followed  by the current contents of the memory involved.  Experienced users may find these screens  helpful in a number of ways: as a database  reference of the BIOS data structure, for quick  access to port address values or the equipment  and memory size bytes.  Experimenters and  students may find these screens helpful in  confirming the effect of DOS and BIOS calls.  ÿÿThe ÿ úFirst Meg Timingsÿ ø screen provide memory  access times for various segments of memory in  your system.  The timings are presented in  tabular form showing: the area of memory tested,  the access time in K (K=1024 bytes) per second  and a comparative index value relative to a  PC/XT timing standard.  In many systems, adapter  memory and ROM memory may be significantly  slower than either standard RAM or add-on  memory.  A system whose present memory capacity  has been acquired over time may also show  significant variations.  A careful use of this screen may help you  determine the benefit, if any, of shadow RAM, or  of memory upgrades you may be considering. ÿÿThe ÿ úExpanded Overviewÿ ø screen shows information  on any expanded memory installed in your system.   If expanded memory is present, basic information  is given, such as the driver name and version  number supporting the memory, the location of the  page frame and the amount and availability of the  memory installed.     Also important is the EMS level of support  provided by the hardware and software as this  determines the EMS capabilities you have.  The  version number gives you this information.   ÿÿThe ÿ úExpanded Pagesÿ ø screen details the first  megabyte of memory as it pertains to expanded  memory.  The vertical table lists sixteen 64K  areas each of which has four 16K segments which  are marked to indicate expanded memory usage.   A legend describing the codes appears at the  bottom of the screen next to this table.  The horizontal table at the top of the screen  lists Logical Page usage, showing the area of  memory used, its size and the number of pages  allocated to the area.  Experienced users may use this display to  confirm installation of memory boards and  expanded memory drivers. ÿÿThe ÿ úExpanded Handlesÿ ø screen lists the handles  allocated to requesting programs by the EMS  driver installed in your system.  The table  lists the handle number, the amount of memory  allocated in K (K = 1024 bytes) and, where  possible, the name or identification of the  program.  You may use this list to determine which of your  application programs make use of expanded memory  and the amounts of memory they are using.  In  some cases (i.e. in DESQview, or by commands to  the application itself), you may be able to  limit the amount of memory the application is  able to acquire if its expanded memory use is  excessive for your purposes ÿÿThe ÿ úExpanded Timingsÿ ø screen shows memory access  times for your system's expanded memory.  The  timings are in tabular form showing: the area of  memory tested, the access time in K (1024 bytes)  per second and a comparative index value relative  to a PC/XT timing standard.    When no application program is using expanded  memory, the display shows only the timing for   available memory.  If expanded memory is being used, you will also see timings for each memory  area. This list is sorted by handle number.    Together with the other timing screens, this  screen may pinpoint ways to improve your system  performance.       ÿÿThe ÿ úExpanded Benchmarkÿ ø screen provides a  benchmark of the EMS manager in your system.   Five sets of tests are performed, giving minimum,  maximum and average timings in microseconds.   These tests are repeated throughout the time  this screen is selected.  The tests show performance values for typical and  heavily used memory management services. The  time spent in an interrupt handler is also a  critical factor.  This figure is reported.  Comparative results of this benchmark on the  same or similar equipment using different memory  managers can show the relative merits of the  products under consideration. ÿÿThe ÿ úExtended Overviewÿ ø screen shows you a map  of the extended memory in your system.  You will  see the range of memory addresses used, their  size and whether that memory is in use or free.   For areas in use, you will also see if the  memory has been taken from the top or your  extended memory or from the bottom.    This screen can tell you if you have extended  memory that is not being used.  It can remind  you of the presence of programs that use  extended memory.  It will often lead you to  other screens to explore an opportunity or  resolve a question. ÿÿ The ÿ úExtended XMSÿ ø screen shows you the XMS  support available in your system.  The level of  support is indicated by the version and driver  revision information.    If you have applications which use XMS, this  screen will help you determine if your XMS capability is sufficient for your needs. ÿÿThe ÿ úDOS Overviewÿ ø screen shows two views of your  DOS Kernel.  The view on the left gives general  information about DOS code and resource usage,  the view on the right breaks this information  down to show the location in memory of these  areas.  The DOS version and the presence of an  expanded memory manager will affect some of the  details of this screen.    A review of this screen is useful in checking or  confirming the presence of required resources for  your system, to pinpoint excessive allocation or  to verify the effect of installing device drivers  or buffers in high memory.  ÿÿThe ÿ úDOS Driversÿ ø screen shows a list of the  drivers installed in your system including the  standard devices present in all DOS systems.  For  all devices listed, the name is given along with  the device characteristics map.  Standard devices  are identified as belonging to DOS in the name  column.  Devices loaded from statements in the CONFIG.SYS file show the memory area they use and  their size.  Although this screen contains highly technical  information, less experienced users may find it  useful to determine which of several installed  devices are contributing to a high device total  memory use.   ÿÿThe ÿ úDOS Filesÿ ø screen shows you information about  your file usage.  The box at the top shows you  the number of file handles and FCBs currently  open and the total number available for your use.   The lower box lists all the files currently open.  Three files are always open: AUX, CON and PRN.   Other open files will be listed by name following  the standard handles.  Only files opened and left  open for a considerable period of time will  appear here.  Experienced users may use this screen to help  track down problems with lost handles or to  determine the correct number of handles needed.   ÿÿThe ÿ úDOS Environmentÿ ø screen shows the variable  names and values for items in your Environment.   Every program, while it's in memory has an  environment.  Some programs use environment  variables to set configuration parameters.    Probably more familiar to you are the PATH and  PROMPT variables which COMMAND.COM uses.   You can use this screen to see what variables   are being set.  If you want to see how your DOS  prompt is formatted, look at this screen.  If DOS can't find a program you want, check your  PATH statement in your AUTOEXEC.BAT file. ÿÿThe ÿ úQEMM Overviewÿ ø screen shows you basic  information about QEMM-386.  A quick look at this  screen will give you the version number for QEMM.  You can tell if high RAM is in use and whether  you have set your ROM to be mapped.  The current  mode and the location of the Page Frame is shown.  Information on this screen is useful when you  need help.  It can guide technical support to  other screens that might help to resolve any  problems using expanded memory.  ÿÿThe ÿ úQEMM Typeÿ ø screens show you a map and a list  of your expanded memory usage.  The map shows you  how each 4K block of memory in your system is  being used.  The list shows multiple blocks of  contiguous memory by type.    You can use this screen to see how you or QEMM  has organized your memory.  You can check to see  if there is high RAM and the size of each region. Information here, along with other screens can  help you make better use of your memory. ÿÿThe ÿ úQEMM Accessedÿ ø screens show you a map and a  list of your expanded memory patterns of access.   The map shows you if any 4K block of memory in  your system has been accessed since the memory  was mapped.  The list shows multiple blocks of  contiguous memory that have been accessed or that  have not been touched.    Areas of memory that have not been accessed might  be available for other uses.  Areas in high  memory could be mapped, perhaps.  These screens  alone will not tell you this definitely, but can  point out possibilities for investigation. ÿÿThe ÿ úQEMM Analysisÿ ø screens show you a map and a  list of an analysis of your expanded memory.  The  map analyzes each 4K block of memory.  The list  shows multiple blocks of contiguous memory by  type.    This information can help you to Include or  Exclude memory, but only if you have carefully   followed the guidelines specified in the QEMM-386  manual.   ÿÿThe ÿ úQEMM Memoryÿ ø gives you an accounting of the  expanded memory in your system that QEMM has  converted from your extended memory.  The screen  shows what, if any, changes have been made to  conventional and extended memory.  It shows  whether high RAM has been made available and the  amount of expanded memory your system now has.   The memory used by QEMM is detailed also.    This information can tell you not only how memory  is being used, but may point out opportunities  for a better use of the memory you have.   ÿÿThe ÿ úDESQview Overviewÿ ø screen shows you selected  information about the window in which Manifest is  now running.  It tells you DESQview's version  number, which is important when you contact  Technical Support.  You can experiment with Move and Resize using  this screen.  When you see a window position you  like, you can use the information from this  screen to start up an application by using Change  a Program and copying the values you see here. ÿÿThe ÿ úDESQview Memory Statusÿ ø screen gives you  convenient access to the infomation reported by  DESQview's Memory Status program.    Common memory shows how DESQview and DESQview  programs are now using the memory set aside for  internal use and program communicication.    Conventional memory shows you how that memory is  now being used.  Expanded memory shows how much memory DESQview is managing and how it is being use now ÿÿThe ÿ úHints Overviewÿ ø screen shows how you might  make better use of your system.  This screen  consists of short suggestions that Manifest has  compiled as a result of gathering all the  information about your PC for its reports.    You should look at the detail screen if you find a suggestion that looks promising.    If Manifest has not found any conditions to  report, the Overview screen will tell you this. ÿÿThe ÿ úHints Detailÿ ø screens give you more  information about the recommendations you saw in  the Overview screen.  The detail screen tells you  why the recommendation is being made.  It also  attempts to point out circumstances where the  suggested action should not be taken.  If you decide to follow the suggestion, you are  instructed about the changes necessary. ÿÿThe ÿ úExitÿ ø screen tells you how to quit Manifest:  by entering ESC (the Escape key).  Actually, you  can quit Manifest from any screen by entering ESC  twice (three times from a Help screen other than  this one).    Thank you for using Manifest.  We hope it helps  when you have a problem.  Better still, we hope  it helps avoid problems that keep you from your   more productive tasks.   ÿÿThe ÿ úExit Stay Residentÿ ø screen tells you how to  quit Manifest, but keep it in memory so it can  be "popped" back up later.  You do this by  entering one of the three key combinations  listed.  Then at the DOS prompt, run the program  whose behavior you want to monitor.  While this  program is running, use the same key-stroke  combination to bring the Manifest screens back.  With this feature, you can see if a program  provides interrupt services (First Meg  Interrupts).  Does the program use expanded  memory (Expanded Handles)?  Can I tell how much  memory the program really uses (First Meg  Programs - if it has an [Available] entry)? ÿÿ
