As it says in the title: AOS4 shown booting on the A1 (Please note that debug option is enabled, this is shown in the video as modem activity). Web site with video's

Negative things: Slow bootup and slow graphics but with unfinished IDE drivers (no DMA ?) it is ok. Gfx is in my opinion slow for G3@933MHz machine despite of 68k emulation. Positive things: In overall proofs OS4 is working and doing progress on A1.

Why show off solid window movement when it seems so slow as it does? :)

I don't really understand the point of this video?
Surely it's better to wait until OS4 is more advanced and then make videos that actually make it look good, rather than releasing videos that show it running so slowly?

People who don't know about all the debug output, 68k stuff and unfinished gfx and ide drivers will just see this "AmigaOS4 on a 933Mhz G4" video and think it's rubbish.

I tried to point out in the post that debug output was enabled, that it one large reason why the boot was slow.

A tripod would be a good investment.

That's not very likely because MorphOS has debug output while booting, too, and there is little effect on performance (besides, at 115 KBps, you can dump thousands of bytes per second). The blinking on the modem looks more like WindowsXP trying to figure out what modem is connect. Such chatting between devices would indeed take a bit of time.

To show that it's real.

Thanks for the video. Window refresh rate is rather good (after the initial opening) for an alpha. The prefs come up very quickly! They seem much more responsive than Amiga 3.9.2, but not as aesthetic as the 3.9.2. This is an improvement over the initial responsivness shown a few weeks ago.

Isn't there a bit more? A command is sent to query the installed firmware. That dumps more or less information, depending on modem, probably at low speed. Followed by the initialization commands for the detected modem. What about detecting the correct seril speed? And I'd assume that, at least with some modems, the initialization sequence includes commands that take a longer to process (like resetting to factory defaults), thus holding up the computer a further second or two. Or not, if that part is in a thread.

ATI1^M ; ATI2^M ... ATIn^M

But actually, this is where you're off.
With RS-232 kit, either the *modem* is smart enough to autodetect port speed, or it isn't. Now, maybe XP starts sending commands at 1200BPS and works its way up, but no other Windows does, and any delays would more likely be pessimistic (and poorly threaded) timeouts in terms of how long it waits for a response.

Like the way some flavors of '9x, with DHCP enabled, will hang the boot process for an extra minute or three in vain hope of obtaining a lease if the network cable's unplugged...

See above.

Actually, fairly instantaneous.

Now, if you have a USB modem, either port speeds are 'obvious' (set by the standard), you're getting what you need to know probing the device anyway, or it's a winmodem and needs practically no configuration anyway. (HCF modems would seem to require the most setup traffic, technically.)

Why there are Prometheus options in screen resolution selection?

Maybe the Voodoo drivers are based on the Prometheus ones?

I agree there's pluses and minuses.

Plus -- It's working on the A1 now to clean up the code and convert to PPC sections that aren't done.

Minus -- Someone may not understand this.

The people I know that are into Amiga computers are knowledgeable enough to understand the debug slowness and the other parts still undergoing change. I, perhaps wrongly, give Amiga, and MorphOS, users a couple extra experience points when it comes to understanding the more technical aspects of the alpha state of the OS and associated video then I would the average PC user viewing the same thing.
