by Pierre Schweitzer 04 Jan '15

04 Jan '15

Dear all, ReactOS will be present this year at FOSDEM, in Brussels, on the 31st of Jan & the 1st of Feb. More information at: https://fosdem.org/2015/ We will have a stand so that you can come and meet the people behind ReactOS! We will dispatch more information about the stand & its location when we have them. We're looking forward to seeing you at Brussels! Cheers, -- Pierre Schweitzer <pierre at reactos.org> System & Network Administrator Senior Kernel Developer ReactOS Deutschland e.V.

Re: [ros-dev] great chance

Just a friendly reminder. The remaining time to participate becomes lesser and lesser. I still think we have good chances as this is organized by heise and they published much news about ros in the last year, so I think they are really interested.

ReactOS could use the publicity, and it might recruit more developers to ReactOS. I have read about CeBIT on heise online (www.heise.de).

StartROM.0 (called startrom.com and startrom.n12 ins the installation media) loads only a 32/64bit PE Setupldr.exe/Osloader.exe image, which is included with every Windows versión based in the NT Kernel, in a compressed form ofc, that's definitive. StartROM.0 is in effect the rought equivalent to STPBOOT.BIN in your example, but enabled for PXE booting. The confusión comes because StartROM expects to find the loader image with the specific NTLDR file name, renaming process which is done by the built-in Windows Server RIS server, when you créate a Windows distribution directory with the provided tools.

Question(s) about FreeLoader
by Hermès BÉLUSCA - MAÏTO 02 Jan '15

02 Jan '15

Hi all, Ive some questions/remarks about FreeLoader. But first lets start with some introduction On Windows (up to 2k3, things changed starting Vista), the boot loader is in two flavours, the usual one (NTLDR) used for loading Windows when it is installed, and another one (SETUPLDR) used only for text-mode setup. NTLDR shows the classical OS menu (as we do in ReactOS), whereas SETUPLDR can be seen when you boot with a Windows setup CD: it shows some kind of text-mode blue-screen, displaying in a status bar the status of loading some boot-time drivers, possibly allowing you to press a function key to be able to give additional drivers to be loaded. After that, things are loaded (HAL, kernel) and the text-mode setup program proper is loaded (usetup.exe aka smss.exe in the disc). Whichever bootloader being considered, it is made of two parts (concatenated): - a 16 (real-mode)-to-32 bits part, lets call it STPBOOT.BIN (to follow the convention of http://reboot.pro/topic/5900-make-your-own-nt-os-loader-ntldrsetupldr/ ), - and a 32-bit one. The 16-bit part is some kind of stub which switches the CPU to 32 bit (and may also contain some utility functions to make real-mode callbacks). This stub is the same for both NTLDR and SETUPLDR, whereas the 32-bit part differs. In the Windows CD, in the \I386 directory you have those files, NTLDR and SETUPLDR.BIN. But if you analyze them, and after noticing the (compressed) files OSLOADER.NT_ (that expands to OSLOADER.NTD, but is in fact a native .EXE), and SETUPLDR.EX_ (that expands to SETUPLDR.EXE, also native EXE), you notice that in fact NTLDR == STPBOOT.BIN + OSLOADER.EXE and SETUPLDR.BIN == STPBOOT.BIN + SETUPLDR.EXE . (EDIT: During writing this mail I discovered that http://en.wikipedia.org/wiki/Windows_NT_startup_process#CD-ROM_boot_image_ph ase mentions the same thing in the Boot loader phase paragraph). On ReactOS we do the same: our FREELDR.SYS is made of a 16-bit part FRLDR16.BIN concatenated with FREELDR_PE.DLL (using the names of the generated files when you compile ROS). Also we had two targets, FREELDR and SETUPLDR, the former for generating the usual boot loader whereas the latter was used for the bootcd. However starting revision 65832 (http://svn.reactos.org/svn/reactos?view=revision <http://svn.reactos.org/svn/reactos?view=revision&revision=65832> &revision=65832 ) both SETUPLDR and FREELDR became the same. Why? What differed them was the support of the boot loading option ReactOSSetup: SETUPLDR was in fact FREELDR *with* the support of this option (in some revisions ago there was also support for some setup-like blue UI, see revision 57933: http://svn.reactos.org/svn/reactos?view=revision <http://svn.reactos.org/svn/reactos?view=revision&revision=57933> &revision=57933 and references within). Starting r65832 the setup support is automatically included in FREELDR. Therefore when we generate the bootcds, we generate a FREELDR and a SETUPLDR but both files are the same binary-wise. Hence the question: Should we still keep the SETUPLDR target, or just directly use FREELDR in all situations?. One may say keep it for compatibility purposes (filename-wise), but then one might just keep only the setupldr.sys file in the bootcd (and remove the freeldr.sys one)? Another question would be: Should we restore a SETUPLDR target (i.e. put setup-oriented code for SETUPLDR only and not in the usual FREELDR) in order to be able, in the future, to implement some sort of on-demand extra driver loading, as Windows SETUPLDR does? A final note, too (plus question): since our recent PXE support (that appears to work! Thanks to Jérôme + Pierre effort, and numerous testers) somebody oriented me to how this is done in Windows: they have a STARTROM.0 file that is the bootstrap (downloaded and ran by PXE thing) which then loads a NTLDR (somewhat). I binary analyzed it and it seems to be of the same nature as the STPBOOT.BIN file, i.e. 16-bit bootstraper. Question: does it load (after download) directly the 32-bit OSLOADER? OR does it load the full NTLDR instead?, i.e. loading the 16-bit NTLDR part (that then loads the 32-bit part)? Answers and comments are highly welcome!! Happy new year to everyone! Hermès.

Avoiding STATUS_UNSUCCESSFUL is usually a good thing.

Ideally, we'd fork comctl32 into two libraries like windows does, but that would probably mean we'd have to fork from wine, moving the maintenance effort to our side. That's why we did not do it yet.
