[Freedos-user] Conventional Memory
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! -Jesse FreeDOS first time user
Re: [Freedos-user] UPX compression, was FreeDOS Post-1.0 todo list
Hi, Michael Devore escribió: After three days of on-and-off hacking on it, I built a mutant UPX 1.25 to compress EMM386.EXE and HIMEM.EXE to work both as a device driver and as a stand-alone EXE file. As almost always is the case, the actual changes were small, figuring them out was the hard part. Very interesting and nice job, Michael! I hope to see a place where to get such a beast in the remaining 20 messages I have to read :) Using the custom mutated UPX will eliminate SY3PACK closed-source issues, including the 80186-level requirements for the [de]compressor (I think that's the SY3PACK minimum CPU opcode req). What will make you sad is that SY3PACK compression actually beats UPX by a few hundred bytes on each of HIMEM and EMM386 files, but file growth is what you'll have to live with to keep the masses happy. SY3PACK winning may be due to the UPX rebuildable open source using the less efficient UCL compression library than the optimal UPX build which uses the closed-source NRV big-brother version. I can't do anything about that, either. So did you manage to build UPX with the UCL library? I tried some time ago, failed and forgot about it. I am not saying that I did a big research, but the simple/plain first try didn't work. So could you make that mutatn UPX/UCL file downloadable somewhere? I am hightly interested on that (provided that it can still compress the regular COM/EXE/SYS files), and furthermore, I think it'd be quite interesting to be used in the whole FreeDOS for all the programs and drivers.

Re: [Freedos-user] re: FreeDOS Post-1.0 todo list
Hi, Eric Auer escribió: So my suggestion is: Review the needs, and think about a new DEVICE variant CPUDEVICE[HIGH]=[minlevel],[maxlevel],[driver and args] or similar, where you could do for example CPUDEVICE=1,2,FDXMS286 ... CPUDEVICE=3,,HIMEM ... CPUDEVICE=3,,EMM386 ... (the CPUDEVICE command would be combineable with n?command=... style FreeDOS menu system, e.g. to select whether to try to load EMM386) Well, for the sake of useability, I'd prefer something like Michael's idea. Something like: IF condition LINE condition can be expanded in the future, but there could be something basic like IF CPU386 ... IF EXITCODE ... (from last line) (this one is tricky) It should also be processed in the same stage as LINE. Anyway, just a suggestion. We just miss someone to put his hands on it (I wish I could).

Huh, I just amused myself by shrinking USBASPI.SYS from 39K to 21K by renaming it to an EXE and poking it with the mutant UPX. The compressed USBASP appears to work fine.

Perhaps it could be in the UPX package as a seperate binary exclusively for packing things like HIMEM/EMM386 and TDSK. I could have sworn I answered a post from you on this topic previously. Hmm, yup, I did. Since you are eager for the mutation, I have uploaded a file called mods-upx125-dos.zip in directory ftp.devoresoftware.com/downloads/emm386 which contains the two modified files, p_exe.cpp and l_exe.asm. These changes were used to compress HIMEM and EMM386 with revised UPX 1.25. They have been working properly so far under the new compression scheme. p_exe.cpp was slightly cleaned up and restored original EXE stack settings so as not to upset more delicate constitutions. Only other change was to the UPX makefiles for my own directory setup and tool versions, which obviously would be of no use to anyone else. Naturally, users are solely responsible for the rest of build, including the UCL library. If for some bizarre reason someone wants the UPX mutated binary build I used under Cygwin, I can put that up, but it seems superfluous. --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
