Hello everyone,
Aleksey suggested that I discuss this here, on the mailing list.
First and foremost, these are enhancements to do for later, much later (what
I would want for the next release is support for RAID / SCSI controllers).
But I know that a developer doesn't actually keep something in his plans
unless he's figured out a way to do it.
I will paste and add additional comments to each of my suggestions.
1. Compatibility with every version of Windows, from Vista until Windows 3.1/
3.11
That means applications written for 3.1 should work flawlessly on ReactOS,
just like apps written for any other Windows. This is probably not hard, as
at least XP does the same thing.
However, drivers for Windows 3.1 most probably do not work. If the user
actually has hardware that was left unsupported since 3.1, he should be able
to use it.
The same goes for the combination Vista-only driver / old Windows '95 or
Windows 3.1 application.
oiaohm said it's not really possible because VxD drivers are not well
documented. So, maybe in the distant future, maybe when Linux devs will have
reversed VxD's on their own. Just don't forget this.
2. Compatibility with DOS**
This will probably not mean DOS drivers, as probably any hardware with DOS
drivers also has some sort of Windows drivers. It would only mean
application compatibility. However, applications with direct access to
hardware will probably have to remain used from within DOS (e.g. BIOS update
software). The major thing are games here. The ideal way to run DOS games
is:
- anything requested by the game is interpreted and passed on to the ROS API
- Glide commands are interpreted and passed on to OpenGL or Direct3D,
resulting in maybe a better image quality, via the use of features OpenGL
has and Glide doesn't.
- software rendering requested by games should be interpreted and passed on
to OpenGL or Direct3D, again resulting in a better image quality.
Of course, this will probably result in a compatibility layer, like you
suggested.
- redbook audio commands should be passed on to ReactOS, who will read in
analog mode or digital mode, depending on what the ROS global settings are
for that specific optical drive.
My own thing about Descent, quickly: the game tries to access file " 1.midi"
but ReactOS plays "1.mp3". I have all the mp3's and will provide them
whenever needed in order to make this happen. This will transform the old
Descent for DOS in the CD version, that had redbook audio tracks.
Such enhancements were also created for Tomb Raider 1, by Paul that created
Glidos ( www.glidos.net ). Please see
http://www.glidos.net/retext.html?lang=en and
http://www.glidos.net/audio.html?lang=en
Whenever Tomb Raider 1 asked for certain textures / audio data, it was
"hijacked" or "redirected" to the better textures or audio files.
Certainly, this DOS compatibility layer would probably need a Glidos-like
application to control various specific settings from various DOS
applications.
Another DOS related thing would be a command prompt (terminal?) in ReactOS
that has drag'n'drop, copy and paste functionality.
Still oiaohm: for the distant future. Got it, understood it, I just want to
convince you to keep it in your plans. oiaohm even said a compatibility
layer already exists.
3. Processors as a devices, in Device Manager *
*
For example, let's say a PC has a Pentium 4 at 3 GHz, with HyperThreading.
Windows XP reports this processor as two identical ones in Device Manager.
ReactOS should also do that. Apart from Windows, if the user does a
right-click on a processor as a device, in the Device Manager tree, and
chooses the Properties page of the processor device, that page should also
mention the SPEED of the processor. More than that, it would be a blessing
to also see the L1, L2 and L3 cache size, FSB and multiplier, like those
SiSoft Sandra / Everest applications report. Maybe even further, the
instruction sets supported - MMX, 3DNow!, SSE, etc.
oiaohm again: can be done, but not right now. Stability and usability beat
extra information. Got it, too. Bug 2644.
4. Clustering
I discussed this with oiaohm and he said it's doable, as soon as ROS gets
Active Directory Server. Only clustered in terms of processing power, the
user has more machines in a cluster and he still sees ROS the normal way, it
just works faster because there are more processors available. No hard
drives in some sort of JBOD, and 3D data is only handled by the "master"
machine(otherwise you need about 10 GB/sec between machines), the one the
user actually interacts with. This is what he said would be the limitations.
I have other details for this, but since it's very far away, it wouldn't
make sense to bring them up right now.
5. Driver extraction tool
I already got one, DoubleDriver, that backs up the drivers for devices in
the device manager. I was thinking about the hardware that only gets drivers
from Windows Publisher (like my MSI Starkey 2.0). Users would need one.
Again, oiaohm said replicating a freeware tool is not high on the list. I'm
fine with that.
6. A Windows Media Center equivalent
**WMC doesn't do much. Just lists program schedules, can do scheduled
recordings, is able to duplicate streams so that you may record whatever
you're watching. It stops suddenly while doing a "record once" capture, when
it should have waited for the user to say stop (it happened on Vista Home
Premium, on a HP laptop). It has a "touchscreen" kind of interface, that
would probably be great on an actual touchscreen, works ok when using a PC
remote control, but is kind of stupid when using the mouse. It can record
from one channel and let you watch another channel if you have at least two
TV tuners in your computer. Naturally, ROS should do this with "n" TV
tuners.
It doesn't have composite or S-video capturing, like the vast majority of TV
tuner software out there. It only captures in Microsoft's special "Microsoft
recorded TV Show" format, extension .dvr-ms I think (no AVI capture, no mpg
capture). It won't let you specify how the tuner provides sound from the
antenna/cable signal to the sound card (PCI audio, internal cable, external
cable, and if any of the last two, what sound card channel it is). While
watching, it should be easier to find out what channel you're on, and what
the time is, via some sort of OSD (on-screen display) that appears when you
move the mouse or something, just like in WMC. The recording should not be
affected by this (i.e. the OSD shouldn't show up on the recording if you
moved the mouse, again just like in WMC). While watching, it's not possible
(or at least not easy) to jump directly to a specific channel, it may only
be used as a TV (next channel, next channel...). If the user tries to switch
channels while recording, he gets "warning, you're recording, if you switch
channels it's going to stop, you want that?" It should just stop, or at
least let the user specify that he doesn't want to see that message again
somehow. It doesn't let the user specify exactly the framerate, video size,
video standard...just the country of origin. And, as an example,
Romaniaofficially uses the PAL D standard on "air" broadcast, that you
can get with
an antenna. But cable providers use PAL B, which is the German official
standard. So, in WMC a guy with cable from Romania must say he's from
Germany or else he won't hear anything!
All of these should be properly implemented in ReactOS Media Center. Apart
from them, "ROSMC" should have all the deinterlacing options and
deinterlacing-method autodetection routines from Dscaler. That program also
offers a whole lot of other image improvement things, like a good enough TV
station logo killer and image de-noising that actually works. Even better
than Dscaler, REMEMBER the settings the next time the user runs the program.
Maybe also provide the user with basic video editing functionality, meaning
most of the features from VirtualDub (the one I find most important is the
ability to edit a film with "direct stream copy", meaning it just copies the
video and/or audio stream, it doesn't re-encode it. Edit as in cutting parts
of the film. In this scenario, the ability to go frame by frame is also very
useful).
And since it's the Media Center and not the Media Player, this should be the
application that rips audio cd's or audio dvd's.
Most of all, it should be "cluster-aware." Regardless of ROS being cluster
aware or not, this one should be.
oiaohm said this is not your job, but a job for other projects. He pointed
me to MediaPortal. I e-mailed all of them (Virtualdub, Dscaler and
MediaPortal) but I doubt they'll combine the three projects. Still, that's
why John User still buys Windows. Linux is all over the Internet (docs all
over forums, drivers all over sites, applications all over sites as well).
Instead, Linux has "cool" stuff like "mousespedometa" (measures the speed
with which you move the mouse). Some people don't even have Internet to get
what they need (X servers, for instance). To be a Windows alternative, it
should contain a lot of things Windows has.
7. Running on 16-bit systems like 286/386/486 in a "ReactOS Essentials"
(equivalent to a stripped-down XP) mode *
*
It should be the same operating system, but in 16-bit mode only. That's an
ideal scenario and I'm sure it cannot be done no matter how good the
programmers are. So, what can someone do on a 286 ? Listen to mp3's ? No
way. Listen to audio CD's, yes, and hopefully digital playback, too. Watch
TV ? Yes, if the user can find an ISA TV tuner (ATI made such tuners, but
they required a PCI ATI video card, and if you have PCI why not get a better
tuner?). Record TV shows ? Not on that kind of computer. Browse the internet
? That may be possible, with some really outdated, 16-bit browser, like the
Internet Explorer for Windows 3.1. And I don't know how many sites will work
on it. Play games ? Yes, either old DOS or Windows 3.1 ones or the ones that
come with ReactOS, written in 16-bit especially for this mode. Join a hive
as either master or slave ? Hopefully it will be possible, but probably in
the year 2015 at least. Use office applications ? Sure, if the user can find
that last Microsoft Office or maybe Microsoft Works version compatible with
Windows 3.1. Run a web server ? I know a guy who had a server running on a
386 system, on Windows 3.11. So yes, it is possible, only I don't know what
software he used to actually serve the data. Act as a router ? Again,
hopefully. That is, if the entire network is on 10 megabit, because I don't
think there are ISA 100 megabit network cards (ISA bandwith is not enough).
2D graphics ? It was possible in Windows 3.1, why not ? Maybe the first
Photoshop versions actually were 16-bit. 3D graphics ? The first 3D Studio
Max (that is, 3D Studio) was for DOS only. That probably means 16-bit right
from the start, and that should mean yes, you can do it, with the DOS
compatibility layer. Web design ? If you can find a 16-bit application, yes.
A separate ReactOS for 16-bit only, or just all the 16-bit functionality
included in the normal ReactOS ? Things look better when it works out of the
box, but it's a waste of space to include applications written for 16-bit
only. People that really need the 16-bit version will not mind paying extra
attention to actually download this one and not the normal one. Besides
that, ReactOS is free. And the presence of such a version would mean a
selfless devotion to people. An act of charity for real. Allowing people to
use their computers and do as many modern things as possible on them.
An open source Windows 3.11 with better compatibility and adherence to
standards. Compatible with all the 9x and ME. Has been tried in Free Win 95,
oiaohm said "dead and staying that way" about it, but maybe VxD
documentation and whatever else you would need will appear (or be reverse
engineered by someone). Once a bigger effort will be done, the missing info
is probably easier to uncover.
Those are my suggestions. They are not for now, they are not easy to do,
etc. Just don't discard them, please.

Hello,
today all servers (web, svn, mailing lists, etc) will most probably
be unavailable for an undetermined amount of time, due to IP
addresses change by the hosting company.
They beg their pardon for the unconvinience.
With the best regards,
Aleksey Bragin.
IopFreeIoCompletionPacket has the opposite bug -- there is an
interlocked push (free) even in the ExFreePool case. There should be a
return following the ExFreePool, otherwise we're corrupting memory.

This is really unneeded. Alpha is one nail away from the coffin being
closed and nobody is even remotely interested in doing a mips port
right now. Please remove them and add a an arm entry.

Hi,
This should be a simple one to fix. I can build the rest of the tree
and make bootcd works

Hi,
I've not had a chance to dig in and see which changeset caused the
issue but since the recent bringup changes I can no longer use the
bootcd on Parallels.

The off-by-one errors are because MmPageArraySize is:
MmPageArraySize = MmHighestPhysicalPage;
and not
MmPageArraySize = MmHighestPhysicalPage + 1;
Just my 2 cents,
Pablo

Is there an offical bringup toolchain posted somewhere or steps on how
to build one from the RosBE sources?

Hi!
My best guess is http://gnuarm.org/
I have no idea of anything else.
