At North Thames meeting, a visitor made a video of OS4 running. Actually OS4 is only Alpha version, but it has a lot of features the person who made that video apprecciated well. As stated on a forum on: amigaworld.net. Video are available in both Mpeg and Windows Media File. I want to advice you that the director of the video cut out some crashes, but he honestly stated that on the forum... (a very correct guy). Enjoy it all.

they should really do something about the slow read of files/rendering of icons..

It has really made progress, the last time I saw it 'live' at Rotterdam.

Quake took ages too load, now it is a LOT faster.

Whenever a demo is shown they should really mention the version number. With so many shows going on I wonder if some people have older, slower, versions than others?

The PIO driver which is used on this demo only does between 1 and 2 MB/S...

That explains why OS4 is impervious to Articia features.

No DMA yet, that's why it's slow.

Har Har Har...

If you paid any attention to posts made by the Friedens left, right & in the center you'd have known that the PIO driver used is infact one they hacked together in a hurry, it's not the driver that'll come with AOS4.

So did my A1200... and icons appeared a hell of a lot faster than that.

Class C Troll - picking on stupid little details to support their agenda when its quite obvious those little details are inconsequential or transient.

a few questions:

1) was it just my computer or was the resolution not too good? I couldn't see a lot of details of what was going on with it - I was using MPlayer on RH 9 to watch the mpg, maybe that's the problem?

2) anybody said anything about whether OS 4 will run on PPC laptops (e.g. ibooks, etc.)? Is it abstracted enough that it would support most PPC hardware barring better performance on 'recommended' stuff, of course?

3) are we still waiting until early next year for it?

Not bad for an alpha release.

"was it just my computer or was the resolution not too good?"

If it was shot on a video camera, you are limited to PAL video resolution, which is much lower than that of the computer screen.

General tip - use a long lens (or long setting on a zoom lens). This makes it much easier to get the image of the screen square on, and reduces any curvature on a CRT screen.

They've said that AOS4 won't suffer from the Articia "thing" (we'll just call it a thing for now) like linux does, is this because they've already tested a DMA capable driver on the A1 and they *know* it works and is unaffected, or are they just guessing they won't be affected, like they did for linux? What I want to know is, if the problem is capable of being worked around by Hyperion in their OS, what's wrong with all these Linux developers who couldn't seem to work around it, or even agree exactly what needs to be done to work around it?

In reply to Comment 13 (T_Bone):
I'm not sure we're going to get a straight answer either way until the complete AOne with OS4 combination is released. When this point is reached it should be factually provable if there is indeed a problem. I would imagine that Hyperion are well aware of this and that any issues will be unveiled by us 'normal' users pretty quickly so I would have thought that any problem, if it does indeed exist, is either limited or easily fixable.

Well as AmigaOne owner I can tell you this,

<The problem is found and they are working on a solution to fix it for LinuxPPC,
that are not agreeing on how to implemented> sad Ole Egil in one of his posts at samfundet.no,

mean while they are working to how to best fixed the problem Ole Egil
have come up whit a patch to remove increase preferments whit out crashing your AmigaOne,

the problem whit the DMA is fixed by limit the maximum transfers rate to about the max,
this is Ole Egil fix, and it's not a complete solution to the problem, the other thing done to increases
performance it to set the ide0=ata66 at the end of the booting environment variable

this some thing you do to limit the overhead,

create a script in /etc/rc3.d/ the content of
"#!/dev/sh"
"echo "max_kb_per_request:15" > /proc/ide/hdX/settings"
this will make the script run at boot up, name of the file should be S<priority><name> example "S01fix"
type shmod 770 /etc/rc3.d/S01fix

this not a complete solution how ever it increase
preferments whit out making the computer unstable.

<sigh> Why do OS4 threads have to degenerate like this? :-(

Since I saw OS4 running first hand, I'll give my impressions:
(yes, something constructive, hint hint)

On the understanding that OS4 has not been running on A1 hardware for very long,
I was *very* impressed. It is already getting close to Amithlon levels,
especially older Amithlons without hardware acceleration of graphics.

The understandable bad points were:
A few programs crashed (with a Reaper window), a few more crashed the system
totally (freeze). But the majority seemed fine, and it is only to be expected
there are a few such bugs so early on. There are programs that crash Amithlon.

Yup, is was a LITTLE slow loading stuff off disk. But fast enough to be usable
IMHO. Once they remove the debug to serial port, have DMA-able disk access,
hardware accelerated graphics (without any P96 hacks), and maybe JIT then we
should see far better performance.

Loading of Quake levels was VERY SLOW, but this was obviouls because it was
outputting approximately 10,000 debug lines to the serial port saying a
FileHandle was NULL. Blame the Quake port!

When a MUI program quits, the Reaper appears. Small bug in MUI or OS4 needs
fixing.

The version of OS4 demoed was NOT the most up-to-date; it was missing the
new SoundBlaster support, the booting off native HD, lack of CD-ROM drivers, and
probably other stuff. It was also lacking drivers for the A1's USB port, but
the actual USB stack seemed to be present...

Good points:
It looked GOOD, with nice Anti-Aliased text everywhere. Yeah, maybe a bit too
Windows-ish, but they are looking to support Themes which will fix that easily.

The ability to have a transparent gradient at ANY angle (not just 90 degrees) in
menus was rather neat. As was the ability to customise the GUI look.

Moving windows was already quite fast (so must have some hardware acceleration),
and the refreshing of stuff previously hidden by the moved window was acceptable
speed.

MUI ran fine, as did the standard GUI, for most programs, despite the serious
reworking of the GUI & Fonts system.

Software-rendered Quake was pretty fast! Timed at 33 fps - not fantastic, but
given all the known issues it is more than playable. Can't remember if this was
the PPC or 68k Quake.

The standard Workbench was pretty bug free (unlike Ambient;), but thats what we
should expect since it is based on existing OS3.x code.


If the CD-ROM had worked, I'd have tried Payback. In fact, this probably
stopped testing of lots of software. Well, I saw enough to know there is a good
chance it would work, and even if not it is likely to be fixed soon.

This squashes most of the stupid claims by red trolls IMHO, so lets stop
fighting & wait for the final proof huh?
