Is this a bug in the mesa code or are we lacking something here?

Re: [ros-dev] [ros-general] ReactOS ISO support has been added in Rufus

Then today may be your lucky day... ;) But first things first (you may skip this part if you're only interested in UNIX, as Rufus is Windows only): Besides ISO support through Syslinux, the new BETA of Rufus [1] also adds the ability to install the ReactOS boot records, so that one can then boot freeldr.sys directly from USB. Unlike what's the case for the ISO, this is a bare install, so you will still need to copy your own freeldr.sys, freeldr.ini and relevant files to the USB. However, the hard part of the install (modifying the boot records) should now be taken care of for you. Now, since this is an advanced feature, it's not made available in the UI by default. To access the bare ReactOS boot record installation, you must first enable Advanced Mode in Rufus, by clicking the white triangle next to "Format Options" and only then will you see "ReactOS" listed in the "Create a bootable disk" dropdown. It's the same way Rufus provides bare installation of Syslinux v4 & v5 boot records. I tested freeldr.sys boot from USB using this method, after copying the same set of files as the one ReactOS creates for second stage installation, and it seems to work as good as one might expect (boots brilliantly, but then runs into ReactOS 0x7b, due to issues with USB support - at least on the systems I'm testing with). I may eventually use this method to support ISOs, but for now, I'll stick with the syslinux -> mboot.c32 -> setupldr.sys for ISO support, while the direct freeldr.sys for more adventurous people. Now, what may be of more interest for UNIX-derivative users, is that what Rufus really uses behind the scenes to install boot blocks is its own integrated version of ms-sys [2]. Thus, since I added ReactOS support in my own embedded version of ms-sys, I also went ahead and produced a generic UNIX version that can install the ReactOS bootblocks from the commandline, for freeldr support. To use it, you'll first need to clone the relevant github repository [3] and then switch to the "rufus" branch of that repo, which is where I added the changes. I'm also providing a fully detailed example of a run (git clone, branch switch, installation, etc), in the attached log, but basically, what you want to run is: 1. Fetching & compiling the source # git clone https://github.com/pbatard/ms-sys.git # cd ms-sys/ # git checkout rufus # make 2. Installing the ReactOS boot blocks on an USB drive, here /dev/sda, after blanking its first sectors: # dd if=/dev/zero of=/dev/sda bs=8M count=8 # fdisk /dev/sda => create a FAT32 bootable partition # mkdosfs -F 32 /dev/sda1 # ./bin/ms-sys -0 /dev/sda => install the ReactOS MBR # ./bin/ms-sys -O /dev/sda1 => install the ReactOS FAT32 PBR # ./bin/ms-sys -p /dev/sda1 => write partition info [REQUIRED!] Then you can just copy your files, and boot the drive. Note that the MBR option is -0 (minus zero) and the second -O (minus uppercase O), and also that your drive _will NOT boot_ unless you also apply the -p option. Oh and if you want to complain about ms-sys (yeah, it would probably be nicer if it used getopt so that you could run multiple options at once), please remember that: 1. I am not the author of ms-sys 2. I use my own non-commandline, non-UNIX compatible version in Rufus This means that, due to time constraints, I have little interest in improving my UNIX/ReactOS version of ms-sys (to add ext2 support for instance). I created it as fast as I could, in the hope that it would be useful for UNIX people (only tested FAT32 - I kind of expect FAT16 to be broken), and I may see with the author (Henrik Carlqvist) if he wants to integrate the ReactOS patches, but that'll be about it. > There ought to be something like "make install DESTDIR=...". Hopefully, now that you can use ms-sys on Linux/FreeBSD, you should be able to add an install step, that can invoke ms-sys to create a whole Live/USB system from scratch, to install the newly generated development binaries. "All" that remains then, is to fix USB support in ReactOS, so that such a system can run as expected... ;) Regards, /Pete [1] http://rufus.akeo.ie/downloads/ [2] http://ms-sys.sourceforge.net/ [3] https://github.com/pbatard/ms-sys/tree/rufus root@sheeva:/usr/src# git clone https://github.com/pbatard/ms-sys.git Cloning into ms-sys... remote: Counting objects: 306, done. remote: Compressing objects: 100% (86/86), done. remote: Total 306 (delta 203), reused 302 (delta 199) Receiving objects: 100% (306/306), 84.59 KiB, done.

My plans for 2014
by Eric Kohl 01 Jan '14

01 Jan '14

Hi! since 2013 is almost over, it is time to make some plans for 2014. My primary goals for 2014 are: - Completing the user account management, user logon and password change. - Fixing winlogon.exe in order to enable users to lock and unlock the computer and to change their identity (log-off and log-on again). - Fix potential bugs in userenv.dll. We need to get rid of the administrator logon hack in syssetup.dll. - Fix the system shutdown: We need to terminate applications and services before the machine shuts down. Secondary goals are: - Implement PNP support for scsiport.sys. - Improvements to PNP and driver installation. - Get some legacy hardware working (parallel port, PCMCIA). The items of this list and their priorities are not fixed. I reserverve the right to make changes to this list or to work on something entirely different, without prior notice. Happy new year! Regards Eric

Win32 subsystem in 2013
by Aleksey Bragin 31 Dec '13

31 Dec '13

Hi, this message is a bit provocative, but please don't be offended by it. You all did a wonderful work during this year. Thank you! It's very good to see the work is going on. Just for fun, when I had spare 15 minutes, I decided to check, what was done in the win32 subsystem during this year by the major, respectable and very old time ReactOS developer, and whether my proposal with Arwinss still stands or not. Here is what I found: (analyzing ~ 62 commits by jimtabor): - 25 revisions: Fixes/hacks of our code (ReactOS-specific bug, works in Wine, sometimes says in comments "//// ReactOS : Justin Case something goes wrong.") (revs 58528, 58562, 58563, 58633, 58773, 58999, 59000, 59201, 60054, 60587, 60590, 60592, 60622, 60626, 60659, 60676, 60677, 60881, 61078, 61079, 61142, 61250, 61251, 61292, 61458) - 13 revisions: Syncs with Wine (revs 59157, 59158, 59159, 60763, 60784, 60807, 60820, 60858, 60863, 60865, 60867, 61244, 61422) - 14 revisions: Own code development or rewriting old code, some of which might have been derived from ancient versions of Wine. (60387, 60389, 60394, 60539, 60599, 60602, 60660, 60682, 60683, 60684, 60718, 60883, 60976, 60992) - 1 revision: attempt to fix a bug found in Wine (revision 60054, issue CORE-6024) You don't need to be a scientist to see that 61% of the changes went into fixing ReactOS specific bugs or just bringing in newer Wine code to fix old Wine bugs. Remaining 22% of efforts was spent on actually developing our own, assumingly better code, and just 1 revision was spent on such a glorious thing as fixing Wine's bug. ReactOS is a just for fun type of project, so I highly appreciate that efforts were put into all of the above! However, I still think that it would be beneficial if someone would put similar efforts into Arwinss to eliminate the need to bring in hacks and fix stuff which works in Wine for years already, and focus on developing only those parts which we obviously can't share (GDI, hardware accelerated graphics, whatever else). I lack time to do this myself, but if anyone volunteers I would be glad to help, share my experience and think up of interesting tasks. Like, getting Arwinss to work in Windows 2003 instead of its native subsystem, which would be a nice test. Regards, Aleksey Bragin
