I don't understand what you are talking about. There was a bug in your program
which remained undetected because it ran by chance in CWSDPMI/DosEmu. That
doesn't mean at all that programs NEED to have this bug "implemented" to make
them run in CWSDPMI/DosEmu.
Now, after the PCXTEST thing has turned out to be a non-issue (as fas as
Jemm/hdpmi are concerned), let's return to the original problem: your
mysterious program which runs with Himem, but refuses to run in Jemm/FD
Emm386. You told us a very vague result ("things work better with DR EMM386")
and then swept this thing under the carpet. So, after my experience with
PCXTEST, I may ask: why don't you provide a download link for THIS unknown
program, so that I can run it under MS Emm386 and/or check otherwise what the
problem is.

Otherwise, what I do is to configure the BIOS for boot from CD first and then HD. So the whenever I insert a bootable CD it just ... boots! I know of another solution the I never tested: you can have a boot floppy that starts the boot from the CD. It was used a lot on old machines that did not have BIOS option to boot from CD. That floppy could be selected from Grub. There must be a way to use something equivalent to the second option but using a program somewhere...

Re: [Freedos-user] JEMM troubles - with VESA LFB
Hi Japheth, > in vesainit.c, search for "/* update */" You told me off-list that I changed a physical address in a mapping and then assumed that the linear address to reach that area would be the same. In other words, I forgot to call __dpmi_physical_address_mapping again after the change.

I think CWSDPMI does 1:1 mappings (physical = linear) when asked to map an area, while other DPMIs tend to allocate arbitrary linear address regions from a heap to keep page tables small or something like that...

Actually the fact that both CWSDPMI (default DJGPP extender) and DOSEMU have no problem with the bug in PCXTEST was the reason why I did not notice the problem in 2004/2005 in the first place...

[Freedos-user] emm386 expanded memory
Hi, I have set up a freedos partition on my laptop, and I am having a problem with expanded memory. Mi.com says "some programs might not recognize expanded memory without a page frame" and indeed I cannot load Master of Magic because it says I need at least 2,700k of expanded memory. I have tried the emm=4096 switch but I can't get it to work. The configuration I started with (emm386 with no switches) worked fine on another machine, so I don't understand what is going on. Can anyone suggest how I might tweak emm386 to solve this problem? Thanks. Charlie Never miss a thing.

There is very little chances that the bug comes from FDUPDATE, as there is no "potentially dangerous" code in it. I cannot really help there, as I'm not an expert on such "low level" stuff. Maybe Eric or Japheth would know what those hex numbers are about... (?) FDUPDATE 0.51 is using WGET to download data from internet, and I think that the bug is sourcing from WGET or your DPMI environement. Do WGET as a stand-alone application works for you? Are you using the latest EMM / JEMM driver? Optionally, you should install CURL and try the FDUPDATE v0.52 (you can configure it to use CURL instead of WGET).

Re: [Freedos-user] JEMM troubles - with VESA LFB
Hi Japheth, strange that PCXTEST crashes for you if only HIMEM is loaded. I did not test it with DPMIONE, but I developed it in DOSEMU and used it with CWSDPMI because the latter is the "official" DJGPP DOS extender. I did not test without HIMEM today, but I guess I did test when I developed it years ago.

This is not a negligible detail, because the original issue is exactly this: why did "something" work with Himem alone but doesn't with Jemm/FD Emm386. I did this for you and can tell: your PCXTEST also crashes without Jemm under simple Himem, it also crashes in a Win9x DOS-Box and it also crashes when DPMIONE is used as DPMI host. The reason is simple: PCXTEST is buggy (yes, I know the bug, but I'm a nice guy and don't want to spoil you the pleasure to find the reason yourself). It happens to run with CWSDPMI, but I'm almost sure this is the only host it really runs with. Didn't you test with your favorite host, DosEmu? It also has LFB support in console mode, AFAIR.

Re: [Freedos-user] JEMM troubles - with VESA LFB
Hi Japheth, > > - the program uses dos4gw but using dos32a instead does not help > > - the program crashes with fd emm386 and with jemm386... > > - the program works okay if only himem but no emm is loaded :-) Well I did more testing... You recommended to use MS EMM386 4.49 or 4.95 of DOS 6 or Win9x, but I only had 4.44 of Win3.1, and it did turn out to be FD HIMEM incompatible? At least it crashed after displaying the startup message and before the next config sys line would be processed, and I could not come up with MS EMM386 options which would fix that...? Or maybe MS EMM386 trashes FS or GS or so? Then it would work with 8086 but not with 386 FreeDOS kernels. So my next test was with DR DOS EMM386. For reference, options are: Jemm386: noems X=TEST VERBOSE ALTBOOT I=e600-ebff (I have also tried max=32m and emx, but did not help) FD emm386: EMS X=TEST ALTBOOT memcheck /VERBOSE (I had added memcheck today, but it did not make a difference) DR emm386: XBDA DPMI=OFF VERBOSE ON EXCLUDE=a000- FRAME=NONE MULTITASKING=OFF The result: Things work better with DR EMM386, but I got more interesting results with PCXTEST, a DJGPP app by myself which shows PCX images using VESA LFB framebuffers in protected mode. You can download it as part of my NEWTRACK eye-tracking DOS software, and of course you need no dual VGA for PCXTEST ;-). The download is at www.coli.uni-saarland.de/~eric/newtrack/ I found out that: - pcxtest always works with dr emm386 - pcxtest fails (while some selector points to c0008000:x...) with fd emm386 and jemm386 in a DEFAULT freedos 1.0 install - but after I found out that some "smart" person had copied the HDMI32 exe file to CWSDPMI exe and put a REAL CWSDPMI in the same place, pcxtest also started to work with fd emm386 and with jemm386... - the funny thing here is that hdpmi32 is supposed to be very compatible with jemm386, same author ;-) - the original cts toasted 96 demo (ctstoast) worked once with dos4gw but not with dos32a if I loaded "cwsdpmi -p" first to keep cwsdpmi as TSR for a moment I believe the latter happens for both Jemm386 and FDemm386, and I believe that ctstoast works with DRemm386 anyway, but I am not sure about those two points. Did not write down all results of my experiments, only a few interesting ones :-). All tests done with FD himem, 1 GB RAM, PCIe GeForce7600/512.

Re: [Freedos-user] wireless internet
Hi Chris, >>> Can Freedos run ndiswrapper? No. Ndiswrapper is a linux program that enables the Linux kernel to use NDIS drivers (drivers written for Microsoft Windows). In contrary to Linux, DOS itself doesn't provide networking. Networking is built either right into the applications or into an external TCP/IP kernel. Most of these applications use "packet drivers", a driver specification developed in the early eighties. Other sorts of drivers are ODI (Novell) or NDIS (Microsoft). As Eric wrote, there is a wrapper called DIS_PKT9 that allows to use NDIS version 2 drivers (extension: ".DOS") as packet drivers. Other wrappers are available for ODI drivers, if you have one of these. Look at lazybrowndog.net/freedos for more info. I can't help with USB, sorry. But for wireless PCMCIA cards check Orinoco 802.11b cards with the wlan42.com ODI driver, they seem to work in DOS. (see: ) Uli - This SF.net email is sponsored by: Microsoft Defy all challenges.

It requires the package WGETX (http://mateusz.viste.free.fr/fdupdate/wgetx.zip) and an active internet connexion to work. *** What's new in v0.52: - Fixed a minor bug in package's description displaying (when used "/new"), - Fixed a bug which caused bad page switching in the "new software" list, - Added support for LSM files with TAB characters instead of spaces, - Added keyboard's buffer flushing after any keypress, - Added internationalisation (NLS) support, - Added Polish translations, - Added French translations. As usual, any comments/suggestions/requests are welcome ;-) If you would like to have a FDUPDATE's localisation in your language, please translate the FDUPDATE.EN file and send it to me, that way I will be able to include it in the next release.
