 Conventional memory is a contiguous memory block _inside first
megabyte_, starting from zero address. If you map memory over graphics
memory area at segment A000 and mono video text at segment B000 (of course,
in this case you may use only color text modes), you may increase
conventional memory from 640k to 640k+64k+32k=736k. To use all other memory,
your application should use XMS/EMS, or should be compiled with/for DOS
extenders (like DOS4GW or DOS32a).

[Freedos-user] conventional memory

[Richard]

Hi

 

I have a custom program that loads into conventional memory.

But in need more than the standard 640kb.
I have 128Mb extended memory.

 

How can I increase the conventional memory as much as possible?

 

Thanks

No, no 1.0 yet (http://wiki.fdos.org/Main/Todo_1_0).

Hello all,
 
Bernd:
I do not have a modem or network card, just a floppy drive in it.  It's just an old thinkpad I play around with. 
Diego & Arkady:
I'm not even really sure what the settings in config.sys do, I was just searching on google for ways to gain more conventional memory, and copied some config.sys examples.  i.e., I have no idea what umb or fcbs is.

You don't need to load high CTMOUSE it'll load high if possible.

You must have DOS=UMB (you have DOS=NOUMB) to enable UMBs, also Do you
really need FILES=100 and LASTDRIVE=Z ?? You can save some memory using
FILES=50 and LASTDRIVE=G. If you use a cache program (recommended) you
can have BUFFERS=10 (no less than 3).

Hope this helps.

I wasn't aware the old FreeCOM didn't use XMS by default. Glad we fixed 
your case.
Just to be curious: do you have a network connection or modem connection 
on your laptop? I'm working on a bootdisk that enables the user to 
download an ISO image to their local machine, and then pretend if it was 
a cdrom. Floppy installation is something I've never tested that well, 
as I usually work in VMware.

Emulators dislike changing removable media.

If you want recent binaries on a floppy disk, see 
http://odin.fdos.org/odin2005/ for disk images.

His current setting is DOS=HIGH,NOUMBEquivalent to MEM /C is MEM /C. Depends on how your FreeDOS is though.Strange that Jesse's FreeCOM uses 75KB of memory while XMS is available.Normal optimized FreeCOM uses 3KB of low (conventional) memory, and

I don't know if that works without DOS=UMB (or in Jesse's case: 
DOS=HIGH,UMB).

Try using "dosdata=umb".  This will load the above values into UMBs, I
think... or something like that.  In any case, it does something to
free up memory, and is different than dos=high/umb

[Freedos-user] Conventional Memory

[Jesse Petre]

Hey guys,
I was just wondering how I could increase my conventional memory?  I'm trying to get Red Baron to run.  I'm new to freeDOS, and I'm not sure what the equivalent to mem /c is, but here are some outputs that hopefully will help.: 

 
mem /u from the command line:
 
Segment   Size    Name  Type
-
0699 96  free
06A0 72176  COMMAND  program
1851  208 free
185F 3328 CTMOUSE  program
1930    547744  free
 
Memory Type  Total   Used  Free
-    -    -  ---
Conventional 639K  104K   535K
Extended (XMS)  80,896K    15,425K 65,471K
 
Largest executable program size  535K (  547,744 bytes )
FreeDOS is resident in the high memory area.
 
 
 
 
 
Here's my autoexec.bat:
@ECHO OFFPROMPT $p$gPATH=C:\FDOS\BIN;C:\FDOS\BIN\KEY;SET NLSPATH=C:\FDOS\NLS;SET LANG=ENSET BLASTER=A220 I5 D1 T3 H6LOADHIGH C:\FDOS\BIN\CTMOUSE.EXECLS
 
Here's my config.sys:
 
dos=high,noumb
device=C:\FDOS\BIN\HIMEM.EXEDEVICE=C:\DOS\EMM386.EXE NOEMS I=B000-B7FF  

FILES =100BUFFERS=20FCBS=4,4BREAK=ON
lastdrive=zshellhigh=C:\COMMAND.COM /E:256 /P
 
I would appreciate any help on this, and thanks!
