Title: AmigaOne XE Mobo + PowerLogix Dual G4 module?
Post by: on November 19, 2002, 04:59:52 PM
Reading the whitepapers on the Artcia S chipset, it would seem that you would be able to pull the G3/G4 processor that comes with the XE board, and replace it with say a PowerLogix Dual 800mhz/1ghz.

Does anyone know different?

No reason why it shouldn't work.

Except the AmigaOS does NOT support multiple processors!

AmigaOS 4.0 will not support SMP?  My memory serves to tell me, way back when it supported multiprocessors.... or was it just AMP?

I have been away from the Amiga scene for along time... so I have very little knowledge of what the AmigaOS 4.0 will have instore... all I know is that I am looking to put together a PPC box, and thought that having an AmigaOS once again would be a nice change from my Wintel world.

I just hope that with Amiga coming back, will bring back those who left not because they wanted too, but because they *had* too....

I am hoping to rekindle my love of the Amiga once again very soon...

AmigaOS has never supported multiprocessing.

While AmigaOS doesn't support smp, Linux does. So, if you get that board maybe (MAYBE) it will work with Linux. I don't know if OS4 will work at all though if you do.

The Big question: Can I buy A1 XE without CPU card?

What makes you people think this card will work in an AmigaOne?

I have news for you. The same processor connector is used in the Apple:

Sawtooth/Gigabit Enet board
Digital Audio/Quicksilver board
Pismo

And guess what, they're INCOMPATIBLE! Just because they use the same processor connector doesn't mean they're interchangable.

Unless MAI or EyeTech says they are compatible (and which one they are compatible with) you're only cooking up a recipie to ruin your hardware.

As strobe allready said, Apple changes the CPU-module-protocols
quite often and this one is only usable in fairly new Macs.

Building modules for those protocols is hard, while using such
a module in a non-Mac is impossible due to a Apple-patent.

The A1 will only be able to host CPU-modules that were made with
the A1 in mind.

Whats the matter?
800Mhz G4 not fast enough for you? :-)

Tickly:

Amiga has "supported" multiprocessing, like the AMP on CSPPC and BPPC cards.

Official SMP support might not appear untill in OS5, if ever.  AMP could be implemented more esily, but apps are harder to write for that. We could for example run OS + normal apps on CPU1 and for example 3D renderer task#2 on CPU2.

strobe:

I think Eyetech announced last spring that they have made an agreement with Apple for the use of Apple MegArray connector.  (and I understand "they" = MAI and that all could be a lie)

But anyway, it is possible in theory. And if the bus protocoll is different, it is anyway pretty trivial for the Mac CPU accelerator manufacturer to tweak the card for A1 or TeronPX.

Time will tell, they  first  need to get the motherboards in shops.

ksk:

That is exactly the reason I asked if it would work on this board, since it uses the MegArray (300 pin ZIF)... also looking at the whitepaper based on the Artcia S chipset, it is compatible with a very, very wide selection of CPU's from x86, MIPS, to nearly all PPC based CPU's on the market.

Like I said ALREADY the connector doesn't mean squat. I mean hell, the Pismo uses the came connector and it has the northbridge chip on the daughtercard.

It isn't trivial to change the "bus protocol" especially considering:

a) Sonnet had a dual G4 upgrade soon after the Sawtooth was released. Many many YEARS later were other CPU modules made available.

b) The A1 market is basically zero. If it took YEARS of  New World Mac sales before there was a market for more than one CPU module upgrade how many decades of AmigaOne sales would it take?

Wake up people, really |-\
