UPCT (Ultra precision command timer) - Benchmarks duration of processes.

unrated

[added 1998-03-26, updated 2005-12-09]

A small utility for benchmarking duration of processes.

Usage: UPCT [COMMAND_SEQUENCE]
Meaning: Any command plus parameters you would normally
enter at the DOS command prompt, including redirection.

To get UPCT to time duration of a batch file run from the command line, try this syntax:

UPCT CALL MY.BAT

Here's the output after running a batch file that turns this web site into a text file:

Command executed: C:\COMMAND.COM /C call HTSTR.BAT
Parameters: HTSTR.BAT
Raw total count: 128403478 cycles on the 8253/4 programmable interval timer.
Elapsed time: 107614357.1 microseconds = 1 minute and 47.6144 seconds.

PC Diagnostics - Hardware diagnostics tool.

unrated

[added 1999-09-25, updated 2004-06-30]

PC Diagnostics '95 (for DOS including, but not limited to, MS-DOS 7/Win95) performs hardware testing – this distinguishes it from traditional system information utils like Microsoft's MSD or Qualitas' ASQ. PC Diagnostics "can check out most aspects of any PC, including modern features such as the PCI, AGP & MCA busses, and handles all types of systems, from an XT all the way to Pentium II. Performs system burn-ins and can even detect intermittent problems." Development of this program has ceased, but it should remain useful for legacy PCs.

While not difficult to use, it is intended for computer technicians / experienced users who are best able to interpret the information generated. Limitations and cautions are fully discussed in the documentation. This tool needs to be run after a clean boot.

PCI and PCI32 - PCI system information tools.

unrated

[added 2000-08-28, updated 2006-03-14]

PCI "...features classic PCI Specification Version 3.0 support, including all 140 device class/subclass/programming interface codes" and "produces a report of the PCI, AGP & CardBus devices fitted to a PC, including the system chipset," as well as "system resource usage (IRQs, Memory ranges, etc), capabilities (busmastering, caching), setup data (device latencies, general capabilities, features, subsystem info), and much, much more." PCI's database (included in every package) currently identifies over 20,000 devices from over 2100 hardware vendors. Note that the database is updated regularly, so check for a new one often.

Major development work on PCI for DOS, Win3.x and Win9x has ended, but updates and bug fixes will continue if necessary. PCI32 for WinNT+ is still in development, and PCI64 is coming. PCI32vk is a package of ports for DOS16, DOS32, OS/2 Warp 3+, WinNT+ and Linux. All versions use the same database file.

All versions use the same data files. All versions are released as freeware, freely modifiable, with PAS source code, but the principal author accepts donations from grateful users.

Usage: PCI [-H] [-D] [-S] [-T] [-B] [-P] [-?]   [] indicates optional parameter

Jemm - Efficient Expanded Memory Manager compatible with FreeDOS, MS-DOS.

unrated

[added  2012-02-01]

Jemm is an Expanded Memory Manager (EMM) for DOS, requiring fewer resources than other EMM managers. Derived from the FreeDOS Emm386 (which is derived from a project published by "c't magazin fuer computer technik" (a German computer periodical) circa 1990.

It is compatible with FreeDOS, MS-DOS,  and other similar DOS's.

Jemm provides the following services to DOS applications:
There exist 2 versions of Jemm:
  1. Jemm386: standard version which needs an external XMM to be loaded.
  2. JemmEx:  extended version which has an XMM already included.
JemmEx most likely is the better choice because it will need less DOS memory than an external XMM + Jemm386.

TSR Utilities (TSRCOM) - Remove memory resident programs that can't remove themselves.

* * * * *

[updated 2005-03-11]

Several TSR programs are listed on these pages – many of which have no option to uninstall themselves from memory. It's often wise to uninstall DOS TSRs [e.g., to free memory when a TSR is needed only temporarily, or when running programs with which a TSR may conflict (e.g., Windows)]. The TSR Utilities are compatible with a wide range of memory managers and can remove TSRs loaded to upper memory. Thorough documentation.

MARK
Marks a position in memory above which TSRs can be released
RELEASE
Removes TSRs from memory
FMARK
Performs the same function as MARK but uses less memory
MARKNET
Like MARK, but saves a more complete picture of system status
RELNET
Removes TSRs marked with MARKNET
WATCH
A TSR that keeps records of other TSRs
DISABLE
Disables or reactivates TSRs, leaving them in memory
RAMFREE
Shows how much RAM is available
MAPMEM

A slick and friendly full screen interface for the SmartDrive cache program: "...allows cache settings to be changed by intuitive point-and-clicking rather than using the less friendly command line options." Change settings for individual drives by clicking on drive buttons and selecting read/write caching options. Current settings are displayed under drive buttons. Good built-in help. EXE size: 14.4K.

F1
Displays brief descriptions of the function keys.
F2
Flushes the disk cache and makes sure that any write-behind (or write-cached) data is written to the disk.
F3
Resets the disk cache – any write-behind data is flushed, and the disk cache buffers are cleared.
F4
Use this to change whether the cache is flushed when the command prompt appears.
F5

OLD PROGRAMS ON NEWER MACHINES

 BORLAND PASCAL 7 CRT BUG 

These programs are intended for users of "fast" PCs (e.g., Pentiums >~200 mhz). They can breathe life back into countless older Borland Pascal compiled DOS programs which may generate an error message on execution ("Runtime error 200 at xxxx:xxxx.") and abort. Several programs listed on this site generate that error. For the end-user, three types of remedies to the TP/BP CRT problem exist: (1) EXE patchers, which modify the original executable (CRTFIX and BP7PAT, or numerous others); (2) TSR runtime fixes (e.g., PROT200TP7P5FIXR200FIX), which don't modify the original exe, but instead detect and prevent the error at execution; and (3) CPU slowers (e.g., SLOWDOWN).

(1) Attempts at exe patching are not always successful because some compressed exes won't be easily uncompressed (required for patching) or may contain anti-hacking code which defeats a successful patch. In addition, patching may infringe upon a program's copyright. Importantly, there is now discussion indicating that some patchers may not be effective for high MHz CPUs (e.g., Pentium II/III >400MHz); you may have to experiment with several patchers to find one that works. CRTFIX is designed to generate a fix appropriate to a PC's CPU frequency. It has the added advantage of offering several options (create backup of original, search for buggy files on disk and log list to file, etc).

(2) The TSR fix can be more desirable if you use a large number of programs with the error. They intercept a BP EXE's divide-by-zero operation, and change the quotient and remainder to real values. Limitations of the TSR fixes include less than 100% effectiveness, and the additional (if small - 1K) memory cost of running the TSR.

Also see J. R. Stockton's pages for more information on the BP CRT issue.

 CPU SPEED 

SLOWDOWN - Slows down PC to allow running of older programs.

unrated

[added 1998-07-15, updated 2003-05-23]

One of the more flexible "slowdown" TSR programs available – freeware or shareware.

From the docs:
SLOWDOWN is a program that temporarily "slows down" your computer so that you can run programs that require a slower computer (usually, a 4.77 MHz PC/XT or an 8 MHz PC/AT)...There are other "slowdown" programs out there that have already been designed and marketed, so what makes SLOWDOWN different enough from the others that I even bothered to write it? The main thing is flexibility... SLOWDOWN can be used to either "permanently" slow down your computer (letting you run several programs in a row, slowly), or to just slow down one particular program (and when that program is done, your computer automatically returns back to its normal, faster speed). Secondly, SLOWDOWN will let you run any type of program – either executable files (.COM or .EXE) or Batch files. Some other "slowdown" programs will only work with COM or EXE files. Thirdly, SLOWDOWN can either simulate a PC/XT, a PC/AT, or can be "fine- tuned" to simulate almost any speed you want it to.

Notes: While progs like SLOWDOWN are usually used to run old games on a fast PC, they can also be used to circumvent the notorious Borland Pascal "Runtime 200" error generated by some old BP compiled programs on faster PCs.

SYNTAX: SLOWDOWN [SLOWDOWN Options] [executable filename w/ options]
/?,/H - Show this HELP screen
/U - UNINSTALL from memory
/Q /V - Be QUIET or VERBOSE about the details (default = VERBOSE)
/E /D - ENABLE or DISABLE the Hot-Keys (default = ENABLE)
/K:ShiftMask - Hot-KEY Shift Mask (default = Ctrl-Alt)
/KeyTable - Show the Table of valid Hot-Keys

/[W]Int8 /[W]Int70 - [Windows] Interrupt to use for timing (default = Int8)
/X[:nn] - Run at the same speed as an XT (4.77-MHz 8088)
/A[:nn] - Run at the same speed as an AT (8-MHz 80286)
/R[:nn] - Run at the REMEMBERED Speed (default = 65535)
/[W]MHz486:nn - Run [Windows] at the same speed as a nn-MHz 80486 (0-5000)
/[W]MHz286:nn - Run [Windows] at the same speed as a nn-MHz 80286 (0-100)
/[W]MHz8088:nn - Run [Windows] at the same speed as a nn-MHz 8088 (0-100)
/[W]P:nn.nn - Run [Windows] at nn.nn% of normal speed (0.00-100.00)
/[W]S:nn - Run [Windows] at a SPEED of nn SU's (0-65535)
/[W:]nn - Slow Down [Windows] by nn SU's (0-65535) (default = 0)
/T - Show TABLE of various computer Speeds in SU's

/C:Yes /C:No - Automatic control of CPU Cache (default = YES)
/Trace:Yes /Trace:No - Automatic Trace Mode (default = NO)
/Beep:Yes /Beep:No - Beep when changing Speed w/ Hot-Key (default = YES)

HBREAK - TSR aids in escaping DOS programs, avoiding system crashes.

unrated

[added 2000-01-08, updated 2005-03-11]

Hbreak is a TSR which allows the user to interrupt programs and prevent some potential system crashes – it's more broadly effective than Ctrl-Break. HBREAK can interrupt a variety of programs (e.g., try it with EDIT). Warnings: Don't load TSRs after HBREAK. The default hotkey is CTRL-ALT-C (modifiable). HBREAK requires around 3.2K of memory, and self-installs into high memory by default. HBREAK /? or HBREAK /H will get the full help text onscreen (easily piped or redirected).

From the help:
  HBREAK 5.5 - System crash recovery utility

HBREAK [/R=0|1] [/T=scan code] [/S=«shifts»] [/ML] [/U] [/?|H]

This edition of HBREAK relocates the first 8 hardware INTs from habitual
zone of 8-0Fh to new zone 50-57h: this is the only alternative location that
MS-DOS 5.0 EMM386 support. This is not conflictive with Windows 3, but /R=0
switch avoid this action...

Activation keys may be selected with /T and /S (to obtain «shifts» value
you must add: 1-Right Shift, 2-Left Shift, 4-Ctrl and 8-Alt)...

/ML switch forces installation in conventional memory (HBREAK is a upper
memory self-installable utility, with or without DOS=UMB statement in the
CONFIG.SYS). /U tells HBREAK to uninstall (if possible). HBREAK takes from
3232 to 3328 bytes of memory in most systems.

Argus

* * * *

[updated 2005-12-09]

Argus packs a big punch for its small (8K) size. It can log access to drives, directories, files and transferred bytes, EMS use, modifications of the INT table, and memory management. I use it primarily to troubleshoot and to discover what file actions some apps perform (e.g., what files are required by a program, log creation of temp files, etc.). Requires about 5K RAM and can be uninstalled from memory. One warning: The log files created by Argus can grow very large very quickly.

[updated 2005-03-31]

KGB is small (2K) and logs only file activity. Unlike Argus, KGB doesn't stamp the log entries with times. The log file is smaller and easier to read compared with Argus's because KGB doesn't record common error messages. Permanent saving of log file. Requires 1K RAM and can be disabled or uninstalled from memory.
