1 Introduction Enhanced DOS for Windows(EDOS) is a unique command line processor for DOS sessions, running in Windows 386 Enhanced Mode. Command line enhancers have been around for several years. Some of them completely replace command.com, such as 4DOS. EDOS is built using completely new technology. It is similar to 4DOS in that it catches commands typed at the keyboard and converts the command into a set of functions that provide some custom feature, like a dir command that sorts entries by alpha or maybe date. What really sets EDOS apart is that it is a VxD. VxD's are what 386 enhanced mode windows is built from. This implies that EDOS is in fact a part of the Windows operating system. A VxD has access to the entire base of Windows code, as well as the hardware machine itself. There is almost nothing that a VxD can not do. By building EDOS as a VxD instead of a real mode TSR, EDOS can have commands that in effect can manipulate any aspect of Windows that can be dreamed of. EDOS has access to any location in memory, to any data structure, to the Windows scheduler, task manager, display control, initialization system, and the list goes on and on. This is not inherently dangerous, but it is powerful. Users can be provided features that allow precise control of the environment. This power is provided by way of a set of commands, the enhanced commands of EDOS, in such a way that the operating system is protected. A brief list of features: 1. EDOS commands will execute in batch files. 2. Change/display pif settings. 3. Display extensive status information about current and other DOS sessions. 4. DOS commands that corrupt disks are disabled. 5. View the clipboard. (4DOS is a shareware product made by another company). 1.1 NEW DOS Commands AltF4 [ON | OFF] STATUS [/? | /v | /l] EDOS [/? | /v | /l] PIF [/?] EMS [/?] XMS [/?] MEM [/?] PRIB [/? | milliseconds] PRIF [/? | milliseconds] SLICE [/? | milliseconds] DOSMEM [/? | k bytes] ALARM [/? | seconds] BOXSWITCH [/? | ON | OFF] BACKGROUND [/? | ON | OFF] EXCLUSIVE [/? | ON | OFF] CLIPBOARD [/? | /VIEW] SYSTIME [/?] BOXTIME [/?] ISWIN [/?] The new DOS commands accept a "/?" option which provides the usual help information. 1.2 Installation Instructions Copy EDOS.386 from the distribution to the Windows Directory. For example: copy a:edos.386 c:\win\*.* This is a special WINDOWS Virtual Device Driver. Not a DOS device driver that would go in the CONFIG.SYS file. To install "EDOS.386", a line must be added to the SYSTEM.INI file located in the Windows directory. This line must be placed in the "[386Enh]" section. The line should look like this: [386Enh] device=edos.386 THEN: Copy ISWIN.COM & CLIPBOAR.COM to the Windows subdirectory. Start Windows, click on the DOS Prompt Icon. When the DOS session prompt displays, EDOS displays it's version number to prove that it's there. - 2 - EDOS loads along with all the other VxD device drivers that make up Windows enhanced mode. When Windows finishes loading EDOS is running(like a TSR), and when you start a DOS session, it is there waiting for you to give it one of it's special commands. NOTE: System.ini contains a reference to EBIOS. This is not EDOS. It is not necessary to make any changes to the EBIOS entry. 1.3 Tested With DOS 3.30, 4.01, 5.00. Windows 3.0a, 3.1-3. 1.4 Requires MS-Windows 3.0+, 386 Enhanced Mode and DOS 3.30+. 1.5 Getting started There is a batch file called "TESTEDOS", suggest that you run it first thing. It demonstrates some of the more interesting features of EDOS. The feature I like the most is the Alt-F4 hot key that causes an exit from a DOS session, just like typing exit plus enter. I don't know about you, but I hate the extra typing and the fact that it takes two hands. With Alt-F4 you can exit from the DOS session with one hand, and the same hot key exits from Windows itself. OPTIONAL INFORMATION It is not necessary to read the following information. EDOS is intended to be usable without resorting to the document file. This information is supplied mearly in case you want to know more. 2 Features included in this registered version SPECIAL DOS prompt that visibly indicates DOS session is running in Windows. See below. - 3 - User definable DOS commands that are disabled. Ability to block switching away from a DOS session. Alt-F4 exits from a DOS session. EDOS thru version 1.30 is a shareware product. This is version 2.00 and is the version provided with registration. (Note: the same documentation file is being used for both shareware and registration versions). 2.1 Alt-F4 ALTF4 [ON | OFF] The hot key combination Alt-F4 will cause a DOS session to exit just as if "EXIT" + enter had been typed at the keyboard. This feature can be disabled in this version. See system.ini switches. Can also be enabled/disabled using the optional parameter ON or OFF. Not included in shareware version. 2.2 STATUS & EDOS STATUS(EDOS) [/? | /v | /l] The /v option displays all (verbose) information. The /l option lists all the sessions: current, other, Windows (system). These two commands display a screen similar to the following: Enhanced DOS for Windows Version 2.00a Free Memory: No Lock or Fix= 516K,Lockable= 516K Swap File Size= K, Type= None Total Paging Mem= 0K, Free = 0K In Use Total= 0 Kc, Contig=? Windows Physical Memory Total= 2200K, Free= 544K Physical UnLocked(in use)= 0Kc, Unlocked= 544K Real Physical Memory Base= 640K, Extended= 3456K, Total = 4096K EMS Free= 0K, EMS Total= 0K, Page Frame Address= E000 hex PageOutCount= 1 Xlate Buffer Segment= 2800hex, Size 8192 bytes Global Min. Time Slice= 21 ms. Current DOS Session Background=N, Exclusive=N Foreground Priority= 100, Background Priority= 50, CPU Time= 66% Memory Used= 164K, Not Mapped= 0K (1K=1024 Bytes) Windows Session(System) - 4 - Background=Y, Exclusive=Y Foreground Priority= 101, Background Priority= 51, CPU Time= 33% Memory Used= 960K, Not Mapped= 0K (1K=1024 Bytes) Explanation of status report: Free Memory: No Lock.. Memory (free) not lockable or fixable Lockable Free memory (lockable) Swap File Size Size of Swap file in K bytes Type None, DOS/BIOS, Direct to hard disk. Total Paging Memory Memory available to the demand pager In use total A calculation of Total-Free = in use. Contig Y=Yes, N=No. Windows Physical Mem Total real memory available to Windows EMS Free,Total EMS memory, free and total available PageOutCount Number of pages on page out list Xlate Buffer Segment Segment & size of translation buffer Global Min. Time Slice Minimum time slice in milliseconds Background Y=Background enabled. N=disabled Exclusive Y=Exclusive enabled. N=disabled Memory Used Memory dedicated to this session. Not Mapped Memory dedicated to session but not mapped in. For/Back Priority From PIF file, priority when in fore/background CPU Time Percent of CPU time assigned to this DOS session 2.3 ALARM ALARM [/? | seconds] The alarm command allows you to set an alarm that will "ring" at the time indicated by the (delay in seconds) parameter. ALARM 5 Will cause an alarm message to be displayed in 5 seconds. You will be returned to the DOS session where the alarm was set. NOTE: only one alarm is allowed in present version. 2.4 BACKGROUND BACKGROUND [/? | ON | OFF] The background command causes the DOS session to have the background mode changed. The background mode status is printed whenever the mode is changed or the command is typed. - 5 - The one allowed parameter turns the setting ON or OFF. 2.5 BOXSWITCH BOXSWITCH [/? | ON | OFF] The boxswitch command enables/disables switching away from the DOS session. The boxswitch mode status is printed whenever the mode is changed or the command is typed. The one allowed parameter turns the setting ON or OFF. (Note: not in shareware version). 2.6 BOXTIME BOXTIME [/?] First invocation starts a DOS Box-time timer. Second invocation prints the elapsed DOS session cpu time. Time is measure in milliseconds. 2.7 CLIPBOARD CLIPBOARD [/? | /VIEW] The clipboard command displays the clipboard status or the contents of the clipboard. Redirection allows the clipboard to be printed. Ex: clipboard /view > prn: (Note: not included in shareware version). 2.8 DOSMEM DOSMEM [/? | K bytes] The DOSMEM allows you to add memory to the current DOS session. Ex: DOSMEM 200 Adds 200K bytes of memory to the DOS session. DOSMEM, with no parameter, displays the DOS session size, the space not occuppied by memory and the amount of memory left in the memory pool. Example: DOSMEM<enter> - 6 - Present DOS memory size= 362 K bytes, 100 K bytes can be added, From= 172K This means that the DOS session is presently 362k, that 100k can be added and that there is 172k from which to get the memory. NOTE: it is not advisable to use all the remaining memory. If 172K is left, don't use more than 100-120k. Leave at least 50k. Presently only works one time in each DOS session. 2.9 EMS EMS [/?] Displays the Expanded Memory minimum and maximum settings for the DOS session. EMS Required= 0K EMS Limit=1024K EMS Free= 0K, Total= 0K 2.10 EXCLUSIVE EXCLUSIVE [/? | ON | OFF] The exclusive command causes the DOS session to have the exclusive mode changed. The exclusive mode status is printed whenever the mode is changed or the command is typed. The one allowed parameter turns the setting ON or OFF. 2.11 ISWIN ISWIN returns an exit code of 3 to indicate that windows 3.xx is running. This exit code may be tested in a batch file, like this: IF ERRORLEVEL 3 goto Windows3 2.12 MEM MEM [/?] Displays the Windows low level memory information. Example: Total Mem= 7804K, Free Mem=5896K (unlocked), Unlocked Mem=1252K Physical Mem=2052K, Free Phys Mem=144K - 7 - NOTE: the most interesting number here is the Free Physical Mem. Which in the example was only 144K. When free physical reaches zero, all new memory is coming from the disk swap file. This has a significant impact on system performance. 2.13 PRIB PRIB [/? | milliseconds] The background priority command(PRIB) allows you to change or display the BACKGROUND Execution Priority of the DOS session. 2.14 PRIF PRIF [/? | milliseconds] The foreground priority command(PRIF) allows you to change or display the FOREGROUND Execution Priority of the DOS session. 2.15 PIF PIF [/?] Displays the pif settings for the DOS Box. (not complete) Sample: Text Emulate No Trap Text No Trap Low Res Graphics Trap High Res Graphics Video Text Mode EMS Required= 0K, Limit=1024K XMS Required= 0K, Limit=1024K VDD Bits = 0017 , VM Status 00004000 COMMAND.COM /E:2000 /C any.bat C:\WIN\_DEFAULT.PIF 2.16 SLICE SLICE [/? | milliseconds] The slice command allows you to change or display the Minimum Time Slice allocated to the DOS session. 2.17 SYSTIME SYSTIME [/?] - 8 - First invocation starts a system-time timer. Second invocation prints the elapsed system time. Time is measure in milliseconds. 2.18 XMS XMS [/?] Displays the Extended Memory required & limit settings for the DOS session. XMS Required= 0K XMS Limit=1024K 2.19 DOS Commands Disabled APPEND SELECT CHKDSK /F JOIN SUBST FDISK ASSIGN FORMAT (use File Manager) FASTOPEN RECOVER WIN Note: This list of DOS commands disabled, contains external commands only. You should be aware that it is still possible to execute these external programs using syntax similar to: C:\chkdsk /f If you are concerned about this possibility, then you should obtain our shareware program system named WINSAFE. 2.20 DOS Commands Modified VER (puts Windows Version + DOS Version). VER /w puts up EDOS version number. TIME (displays time, no altering. Use Control Panel). DATE (same as time). CHKDSK ( /F not allowed, all other options ok). MEM puts up Window related memory information. 2.21 DOS Commands User Disabled To disable a DOS command (or program) from running, insert the following line in SYSTEM.INI, in the [386enh] section. EDOSCommand=xxxxxxxx - 9 - for example: [386enh] EDOSCommand=FORMAT EDOSCommand=COMPRESS EDOSCommand=COPY These 3 commands would disable FORMAT, COMPRESS and COPY. Each line will disable one DOS program or command. Up to 20 such EDOSCommand(s) may be used. (Not included in shareware version) 2.22 Batch Files These new DOS commands will execute in a batch file just like any ordinary command. Extensive use of this feature will allow you to eliminate many pif files. 2.23 Ingenious ways to use the new commands Since DOS sessiones have never had these new commands and since I have not had time to figure out all the clever ways to use them, you will have to figure the clever uses yourself. Or, wait until the next release, when I may have documented this for you. In the meantime, I would deeply appreciate any suggestions you may have. Use my CIS account number, send E-Mail. Thanks. 3 Custom DOS Prompt If the PROMPT that you ordinarily use ends in "$g" or "$l", then whenever Windows is running the "g" will be changed to a "l" or the "l" will be changed to a "g".(g & l are used as special command markers. The g= ">" and the l= "<". The practical effect of this is that your Windows DOS session prompt will be toggled from: C:> to C:< or C:< to C:> To disable this feature place the following line in SYSTEM.INI next to the line you inserted "device=edos.386". "EDOSPrompt=0", like this: - 10 - [386Enh] EDOSPrompt=0 device=edos.386 Once the EDOSPrompt line is placed you may turn the feature back on, by changing the "=0" to "=1". Like this: EDOSPrompt=1 Note: this is NOT the most elegant way to fix this very annoying problem. It will not work for everyone, however, it is the simplest fix and it WORKS! NOTE: This feature is only included in the registered version. 4 Suggestions 4.1 Getting the most out of EDOS If you want to gain the most advantage from EDOS, you should change your strategy for creating PIFs. The single biggest change is to specify: Memory requirements: Required = 64k, limit = 128k Specify a batch file to run. Program filename: comnd.bat (or whatever). In comnd.bat: %COMSEPC% The end result of all this will be a DOS session that starts up with 124k. The top line of the screen will give the EDOS sign-on message. And, command.com will be run from the the default COMSPEC location. - 11 - By running a batch file from the PIF you gain great flexibility and any EDOS commands can be executed when the DOS session starts. 4.2 Edos message at DOS session startup If you run a batch file instead of command.com, then add a "@ver /w" command to the batch file.(This is no longer necessary as of EDOS v2.00). This will give you a screen that looks like this, when you first start up a DOS session. Enhanced DOS for Windows(EDOS) Ver. 1.xx Microsoft DOS 5.00 C:\< 5 Known Bugs Amount of free system memory has a bug in Windows?. Error messages that DOS is less than version 3.30 or ASSIGN, APPEND is loaded, do not display.(works ok in Windows 3.1) Redirection does not work right for MEM & HELP commands. Alarm sometimes will cause a memory corruption, IF a hot key sequence is executed at the same time the alarm message would be coming up. XT class machines with Intel Inboards or similar accelerator cards will not have the correct counts for extended physical memory. 6 Updates Today is 2-12-92. EDOS is essentially complete. Do not expect any major changes for a couple of months. 7 Advanced Information 7.1 DOSMEM This command is the most technically sophisticated, and potentially environment sensitive of all EDOS commands. It has been tested with DOS 3.3, 4.01, 5.0., also Windows 3.0a and - 12 - 3.1-2,3. The method by which memory is added to a DOS session is tricky. Until I have received more reports from the field, it is safe to say that any exotic memory environment or other version(s) of DOS may not work correctly. If you experience crashes associated with adding memory and the DOS session going berserk, please let me know, provide details as to your Windows & DOS versions, and config.sys settings. As soon as I am sure that the code for this command is stable, I will add features to add memory repeatedly(now disabled), and to subtract memory, among others. 7.2 System.ini switches With default condition EDOSALTF4=<True> EDOSPrompt=<True> EDOSCommand=<blank> EDOSPrtScr=<True> 7.3 EDOSPrtScr EDOSPrtScr defaults to true. Which means that The hot key prtscr is reserved to your DOS application; and that print screen will work as normal in that DOS, output will go to the printer, not the clipboard. You may set this to false in system.ini. In which case prtscr will send screen output to the clipboard. This is the Windows default. 7.4 Status When getting a status, some of the memory values will seem strange. For instance, the size of the DOS mem is larger than the amount of memory that DOS 5.0's mem command reports. The reason for this is that EDOS is reporting the amount of memory in PAGES (4k) that Windows is using. Status converts the page count into a byte count by multiplication. Example: Status reports DOS mem=684k DOS 5.0 mem reports conventional memory as - 512k The difference is the wrapper that Windows provides, and includes the display memory buffer and other data areas that are "instanced". "Instance" means that Windows makes a local copy in - 13 - each DOS session of that data. Data which gets instanced includes: the low vector table, the display buffer, etc. The XLATE buffer segment address is the location that DOS uses to store read/write buffers until Windows can copy them into extended memory. 7.5 Making sense of conflicting numbers You may assume that the numbers shown by EDOS are in fact accurate. They have been checked for bugs(in EDOS). However there are bugs in Windows and I have no control over those. Any bugs reported will be dealt with, where possible. 7.6 VDD Pif Bits The VDD pif bits will receive a better report in a later release. 8 Acknowledgments To the authors of "Windows 3 Secrets", Brian Livingston and Undocumented DOS, Andrew Shulman, et all: EDOS might never have been, were it not for the inspiration I received from these two books. Brian's book has been combed from cover to cover, for months. It is the book I fall asleep reading. There may not be any end to the goldmine that lies within it. Every day I wonder how I can find any more insights; and then I find another. The list of EDOS features is rich, due in no small part to Windows 3 Secrets. Undocumented DOS is almost as bad. Andrew's book may be nearly deaf and blind about Windows, but a flash of insight while reading the chapter on memory management led to the feature that allows EDOS to change the amount of DOS session memory, on the fly. 9 Viruses EDOS is written in assembly language, in 386 protected mode and runs at ring 0. There are no known viruses which can infect a file of this type. That does not mean that one will not arise. However, EDOS is much harder to infect than an ordinary, COM or EXE file. - 14 - 10 Optional Files 10.1 Extra PIFs Included is a PIF file, that will make setting up EDOS easier. 0-64.pif a default pif with DOS memory settings of 0k, 64k. Also included is COMND.bat: a batch file that 0-64.pif runs. 10.2 GRP file (empty) 10.3 Creating a DOSBOX group file (empty) 11 Features Implemented Detect duplicate install of EDOS. Detect VWPD installed, disable install of EDOS. Detect permanent swap file, provide state of it in status. Detects SHARE not installed. Version 1.01 Detect DOS is 3.30 or greater. Detect ASSIGN or APPEND is loaded. PRI(B,F), SLEEP, ALARM, SLICE, EMS & XMS commands added. PRI(B,F), SLEEP, SLICE, ALARM accept a parameter. APPEND and ASSIGN, if loaded, will cause a warning message. BACKON, BACKOFF, EXCLON, EXCLOFF commands added. Version 1.10b Fix for DOS 3.30 not loading EDOS. Version 1.10c Fix for Chkdsk begin run /F. (chkdsk /V/F). Version 1.10d Fix for Swapfile type, and MEM command installed. Version 1.5c PIF command, similar to status, displays pif settings. EMS & XMS commands display free and total available. Swapfile now displays the type. BACK(ON,OFF) changed to BACKGROUND. EXCL(ON,OFF) changed to EXCLUSIVE.
