The chipset dependencies of AmigaOS are located in three areas of the OS and nowhere else (anymore):

1. Exec

2. Certain device drivers & resources (timer, cia, IDE, gameport, keyboard, serial, parallel, audio etc.).

3. graphics.library

1) As you know we already have ExecSG running on the A1 hardware so this not an issue.

2) Most of the device drivers need to be re-implemented. This is gruntwork but luckily highly modular. You don't need a serial device before you can start on a parallel device etc. This work is already under way but the main developers are still on OS 4 itself rather than the devices.

3) graphics.library contains hardware banging start-up code. This would need to be replaced or patched out by Picasso 96.

The chipset dependency issue is really overrated.

Well, you are referring to the conversion of a 68K device to a PPC device using the same underlying hardware.

This is ofcourse relatively straightforward, especially with the toolkit we have developed.

What I was referring to was reimplementation for different hardware.

@HyperionMP:
A couple of comments above say that 68K emulation needs to be completed.  I was under the impression that OS4 will not use the 68K CPU at all, just the PPC emulating the 68K as necessary (hence no context switches etc).  Which is it?

You are seriously mixed up here.

I'm sure you are aware that we want to be able to run 68K applications on OS 4?

How do you propose we do this without an emulation layer?

Besides, why would be waste our time to reimplement certain 68K ASM modules in C when there is no need because 1) they are not particularly performance critical or 2) they are intended for the old hardware.

There is very little 68K ASM code left in OS 4 but we have no particular desire to for instance replace the 68K ASM code in graphics.library dealing with AGA with C code.

Or to reimplement SCSI.device when the real bottleneck is the throughput of the IDE controller.

Waste of time if you ask me.

>So what's preventing Hyperion from porting OS4 to the pegasos?

why do pegasos need OS4 ? Morphos isn't enough ?

plus, of the 600 morphos users out there, how many percent would run/buy OS4 ? most people seems happy with morphos, so why pay 50-100 $ or
whatever the price might be for OS4 ?

morphos is free, linux is free, Aros is free
openBE(?) is free, on pegasos everything is free :-D
so why should anyone pay for an OS ? :)

600 is two times more than 300 isn't it?

Genesi's unwillingness to obtain the proper license from Amiga Inc, AFAIK.

yes, your math is correct :)

and this math fit into this discussion because ?

300 users on the devlist I think, but not everyone who has an A1 is on the dev list.
Its upto dealers to add people. I beleive Eyetech add people as an when people request to be on it.

As for 600 users I thought that was the total number or Pegasos's
But people in other threads are saying their are pegasos still available for sale even for $299

so who is lying

600 users or 600 boards (Not all sold which doesnt make 600 users)

Of course, everything depends on timer.device. So it's _highly_ modular, but not completely.

$299 for a Pegosos mb?   I looked at magnetic systems site, and they dont even have a way to buy online?  Where CAN you buy one of these boards?  $299 sounds good to me!

Why are some people so driven to create flamefests? I will repeat, what is wrong with people wanting options? Don't tell me you really think OS4 will be the ultimate end all OS, even Hyperion wont tell you that.
Someone has to state the obvious and that someone is me!

I've heard the number 600 when referring to Articia chips, so I think the 600 users bit is a bit of a lie. But there's still more Pegasos boards out in the field than AmigaOnes, afaik. However, at the current rate of shipping, this won't last for long.

do you se any flamefest here ? if so, didnt mean to start one, but seriously why do people still asking Hyperion/Hermans for a OS4 port, when they should be asking and paying Amiga Inc for that. Everyone knows this by now ?

so stop with the stupid questions already.

Hahahaha!

Even as the eternal optimist here (that glass is ALWAYS half full), I can't see OS4 anytime in the next few months.  That doesn't mean that I'd feel bad about being proved wrong!
