To: opendos AT delorie DOT com Reply-to: Matthias DOT Paul AT post DOT rwth-aachen DOT de Message-id: Organization: Rechenzentrum RWTH Aachen Precedence: bulk On Thu, 14 May 1998 Jonathan Roberts posted his configuration files. Here are a few suggestions to improve performance, and get a better memory footprint: AUTOEXEC.BAT: > C:\MSCMOUSE\gmouse.com LH C:\mscmouse\gmouse.com > SET TEMP=C:\DRDOS Tz, please avoid using such directories as trash/junk directory... ;-) MD C:\TMP SET TEMP=C:\TMP SET TMP=%TEMP% > NWCACHE 7670 1024 /LEND=ON /DELAY=OFF VERIFY OFF LH NWCACHE 7670 1024 /LEND=ON /DELAY=5000 > LH /L:2,55168 COMMAND /E:1024 /CC:\utils\fos.bat ??? > ****** CONFIG.SYS * As already said in the replies, please try to defragment your UMB area to get a single continous chunk. This will reduce left-over unused areas, and also will allow to loadhigh much larger drivers. > DEVICE=C:\DRDOS\EMM386.EXE DPMI=OFF FRAME=AUTO I would also suggest /VIDEO=ON and /XMSUMB. For advanced purposes, I would also use /USE and /RAM options. Since you're using NWCACHE, you should load DEVICE=c:\drdos\dmps.exe here, too. > BUFFERS=15 If you were not using a cache, I would increase this to 30-40, using HIBUFFERS=35. However, I would prefer reducing this to 3-10 and loading NWCACHE instead. This will give you much better performance. HIBUFFERS=5 > FILES=30 FILESHIGH=30 > FCBS=16,16 Usually not necessary any more. Try FCBSHIGH=4,0 > STACKS=9,256 Usually not necessary on compatible machines. Try STACKS=0,0 > SHELL=C:\COMMAND.COM C:\ /E:1024 /P SHELLHIGH= SIZE=1B00 c:\drdos\command.com c:\drdos\ /E:1024 /MH /P I always forget the optimal value for SIZE. Please use the smallest value, which still allows to load COMMAND.COM into the HMA.
