Hello: I am running Windows on a 386sx with 4 megs of (extended) RAM. I find that I can run Windows just fine in 386 Enhanced mode, but that it doesn't run in standard mode or real mode. I have reproduced the contents of my autoexec.bat and config.sys files below. Any comments on them would be welcome. I am using DOS 5.0. After loading DOS, I get about 615K of conventional memory free, and about 57K of upper memory free. CONFIG.SYS BREAK=ON BUFFERS=10 FILES=30 LASTDRIVE=E SHELL=C:\DOS\COMMAND.COM C:\DOS\ /E:256 /p STACKS=0,0 DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.exe noems DEVICEHIGH=C:\DOS\ansi.sys DEVICEHIGH=C:\DOS\smartdrv.sys 2048 512 DEVICEHIGH=C:\DOS\MOUSE.SYS DEVICEHIGH=C:\DOS\SETVER.EXE DOS=HIGH,UMB and AUTOEXEC.BAT @ECHO OFF VERIFY OFF PATH C:\EXCEL;C:\DOS;C:\WINDOWS;C:\;C:\MOUSE;C:\WORD5;C:\DNASIS;C:\OLIGO;C:\BATCH;C:\EDITOR;C:\VIRUS;C:\WINWORD prompt $e[32m$p$e[31m$g$e[36m loadhigh c:\dos\fastopen.exe c:=50 VER set TEMP=C:\WINDOWS\TEMP del c:\windows\temp\*.tmp win The following programs and drivers are loaded in conventional memory:- msdos.sys himem.sys emm386.exe command.com and the following are in upper memory:- System Ansi.sys Smartdrv.sys Mouse.sys Fastopen.exe Setver.exe As I mentioned earlier, I have about 615 kb of conventional memory free, and about 57.5 kb of upper memory free. I have no problems when I run windows in 386 enhanced mode, and I don't really need to run in Real or Standard mode. However I would still be interested in knowing why I cannot run windows in either of those modes. Thank you, Ashok -- Ashok Aiyar axa12@po.cwru.edu aiyar@cwbio.bioc.cwru.edu

I don't know why you can't run in standard mode; what are the symptoms? Joe Morris
