Errors when running under NT
Most common error is DOS Error 4 - running out of file handles...
Action |
The following info may be helpful in getting your CMS application to run under NT...
The most important point to remember when configuring NT is: NT DOES NOT READ CONFIG.SYS AND/OR AUTOEXEC.BAT !!! NT looks for, and reads AUTOEXEC.NT and CONFIG.NT (by default - or whatever files it is told to read...)
The following are heavily commented AUTOEXEC.NT and CONFIG.NT files.
AUTOEXEC.NT
@echo off
REM AUTOEXEC.BAT is not used to initialize the MS-DOS environment.
REM AUTOEXEC.NT is used to initialize the MS-DOS environment unless a
REM different startup file is specified in an application's PIF.
REM Install CD ROM extensions
lh %SystemRoot%\system32\mscdexnt.exe
REM Install network redirector (load before dosx.exe)
lh %SystemRoot%\system32\redir
REM Install DPMI support
lh %SystemRoot%\system32\dosx
SET CLIPPER=F71
REM End-of-file
CONFIG.NT
REM Windows NT MS-DOS Startup File
REM
REM CONFIG.SYS vs CONFIG.NT
REM CONFIG.SYS is not used to initialize the MS-DOS environment.
REM CONFIG.NT is used to initialize the MS-DOS environment unless a
REM different startup file is specified in an application's PIF.
REM
REM ECHOCONFIG
REM By default, no information is displayed when the MS-DOS environment
REM is initialized. To display CONFIG.NT/AUTOEXEC.NT information, add
REM the command echoconfig to CONFIG.NT or other startup file.
REM
REM NTCMDPROMPT
REM When you return to the command prompt from a TSR or while running an
REM MS-DOS-based application, Windows NT runs COMMAND.COM. This allows the
REM TSR to remain active. To run CMD.EXE, the Windows NT command prompt,
REM rather than COMMAND.COM, add the command ntcmdprompt to CONFIG.NT or
REM other startup file.
REM
REM DOSONLY
REM By default, you can start any type of application when running
REM COMMAND.COM. If you start an application other than an MS-DOS-based
REM application, any running TSR may be disrupted. To ensure that only
REM MS-DOS-based applications can be started, add the command dosonly to
REM CONFIG.NT or other startup file.
REM
REM EMM
REM You can use EMM command line to configure EMM(Expanded Memory Manager).
REM The syntax is:
REM
REM EMM = [A=AltRegSets] [B=BaseSegment] [RAM]
REM
REM AltRegSets
REM specifies the total Alternative Mapping Register Sets you
REM want the system to support. 1 <= AltRegSets <= 255. The
REM default value is 8.
REM BaseSegment
REM specifies the starting segment address in the Dos conventional
REM memory you want the system to allocate for EMM page frames.
REM The value must be given in Hexdecimal.
REM 0x1000 <= BaseSegment <= 0x4000. The value is rounded down to
REM 16KB boundary. The default value is 0x4000
REM RAM
REM specifies that the system should only allocate 64Kb address
REM space from the Upper Memory Block(UMB) area for EMM page frames
REM and leave the rests(if available) to be used by DOS to support
REM loadhigh and devicehigh commands. The system, by default, would
REM allocate all possible and available UMB for page frames.
REM
REM The EMM size is determined by pif file(either the one associated
REM with your application or _default.pif). If the size from PIF file
REM is zero, EMM will be disabled and the EMM line will be ignored.
REM
dos=high, umb
device=%SystemRoot%\system32\himem.sys
FILES=150
You may also create the following files: These files are the AUTOEXEC.NT and CONFIG.NT files with most of the comments removed...
AUTOEXEC.ST (for Stockroom...)
REM Install network redirector (load before dosx.exe)
lh %SystemRoot%\system32\redir
REM Install DPMI support
lh %SystemRoot%\system32\dosx
SET CLIPPER=F71
CONFIG.ST
dos=high, umb
device=%SystemRoot%\system32\himem.sys
FILES=150
Screen shot of Shortcut below....
This is a shot of the shortcut for a CMS Application. Click on the Windows NT button...
Create these files (CONFIG.NT and AUTOEXEC.NT) in the SYSTEM32 directory. Then in the shortcut properties, select the Program tab, the click on the Windows NT button. The "Custom MS-DOS Initialization Files" dialog appears. Change the names of these files from AUTOEXEC.NT and CONFIG.ST to AUTOEXEC.ST AND CONFIG.ST
Rebooting is not necessary after making these changes. If you continue to get DOS ERROR 4 errors, change the FILES statement to FILES=255. The software typically works with FILES=100. It may be possible that there are too many open applications on the system. Close all applications and then run Stockroom Inventory Manager. No errors now? Errors are due to running out of system resources with the existing configuration/open applications.
