ReactOS 0.3.4 Hardware Support
by Cam 20 Oct '07

20 Oct '07

Hello, I think that 0.3.4 should have most hardware regressions (floppy and vga) fixed. I know I'm not the one to say this but, we are already closer to this goal than we were with 0.3.3. Fixing the floppy regression should only involve finding the spot in which floppy is not reporting correctly to ntoskrnl. I did some tests on this issue and it fails on line 596-598 of ntoskrnl\io\iomgr\volume.c and floppy was never mounted as the status reported was STATUS_IO_DEVICE_ERROR from line 1017-1021 in drivers\storage\floppy\floppy.c. I don't know much about the vga regression but I'd think that it may only require a few days work to find and fix the issue. We already have SATA support included with trunk (uniata.sys) and SCSI is also working now. -aicommander

Porting ReactOS to the L4 micro-kernel
by Henning Schild 20 Oct '07

20 Oct '07

Hi there, i am thinking of porting ros to the L4 micro-kernel as topic for my diploma thesis. The operating systems group in Dresden already ported Linux to L4 (http://os.inf.tu-dresden.de/L4/LinuxOnL4/) and proofed that L4 offers all that is needed to run an operating system in userspace on top of it. The goal of the work would be to be able to run windows applications next to miro-kernel applications. And to compare the performance with that of pure ros, L4Linux/wine and windows. A comparison between the port and L4Linux could also be part of the work. (mapping processes to L4 tasks, memory management, interrupt-handling and so on) I am not very experienced in C or assembler programming but am motivated to learn. But before i start working on that topic i have some questions on the portability of ros. In svn and on the ros website i found that there is a ppc port of ros. And on irc someone told me that there is ongoing work on a ros usermode port. I also read about a xen port. But i did not yet find working copies of the any of that ports. I built ros for i386 on my machine and was able to boot it in vmware. I also tried building the latest svn version with ROS_ARCH=powerpc but that did not succeed. 1. Did anyone ever finish a port to another arch? 2. How portable is ros in general? Meaning how much code would have to be changed. I hope there are abstractions and only 10-15% of the kernel would have to be changed. 3. Do you believe that one person new to ros can finish that kind of work in 6 months? I know that might be hard to answer but how long did any of you need to learn ros in detail? 4. If there are working ports, how long did it take to implement them? If there are not, what are the reasons they where never finished? I am thinking of lots of assembler and i386 hacks. 5. Finally, what do think of the idea itself? I hope you take the time to answer my questions. I am still on the way to determine whether i really want to do that and whether i can do this in 6 months. regards, Henning Schild

Re: [ros-dev] Targeting multiple Windows versions
by Aleksey Bragin 19 Oct '07

19 Oct '07

Hi Marc, the patch / bug IS valid, Magnus made a mistake and closed it. I wanted to do the same, but it's rather timeconsuming, so I appreciate you took the first steps. Still, some modules may require setting some specific version - that's allright, we can leave some exceptions for now, but otherwise, version number should be set globally, not in every .rbuild file (which is so wrong). WBR, Aleksey Bragin.

Re: [ros-dev] [ros-diffs] [mnordell] 29653: Patch from aicommander. Actually copy uniata.sys from the installation media, and disable VGA resolution selection as VGA is broken.
by Aleksey Bragin 18 Oct '07

Shouldn't it be finally fixed, instead? I don't know who broke it. Was it Magnus with the "No PNP videocard" commit? WBR, Aleksey Bragin.

Re: [ros-dev] ReactOS on VirtualBox
by Mike Leahy 17 Oct '07

17 Oct '07

It's in the User FAQ - third-last question, at the end of the answer it says: "Other virtual machines/x86 emulators should be able to run ReactOS as well, and ReactOS is known to run in at least Bochs, VMWare, VirtualPC and QEMU. If you know of other virtual machines that support it, please send an e-mail to the ros-dev mailing list." I didn't see any mention of it in the recent archives of the mailing list, so I thought I'd mention it. Sorry if I misunderstood. Perhaps I'll try out the other emulation tools, though I've found VirtualBox in general to be very easy to use.

ReactOS on VirtualBox
by Mike Leahy 17 Oct '07

17 Oct '07

Hello list, As recommended in the FAQ, I thought I'd mention that I gave ReactOS a try as a virtual machine using VirtualBox (http://www.virtualbox.org), and it seems to work okay. It wouldn't be too difficult to post a VirtualBox virtual disk image file, though it only took a couple minutes to setup from the installation CD image. I'd like to know if anyone else has given it a try though, as I had some stability problems (random freezes, etc.). I look forward to the future releases of ReactOS. Regards, Mike

Doubts about the header changes in r29178
by Colin Finck 15 Oct '07

15 Oct '07

Hello, Hervé added some Standard C library headers to the "include/crt" directory in r29178. Now some people noticed that these changes broke building ReactOS components with MSVC using the ReactOS headers ("Debug - ReactOS headers" or "Release - ReactOS headers" configuration). I have some general doubts about these changes. >From my knowledge, the headers added in this commit, are compiler-specific and target-independent. You can easily see that they are specific to GCC/mingw as for example "stdio.h" includes a "_mingw.h" file with mingw-specific stuff. "stdarg.h" even leads to compilation problems with non-GCC-compilers (like MSVC), because it defines a type based on the __builtin_va_list type, and this built-in type only exists for GCC. In my opinion, this commit should be reverted. This way every compiler will use its own Standard C library headers and MSVC should be able to build ReactOS components using the ReactOS Win32 headers again. Regards, Colin
