I think I may be able to update a Promise PCI disk controller with firmware for the Sonnet Tempo100 card (which would allow the card to be used in a Powermac).
I don't see any listing on the MorphOS site for ATA100 controller support (just SCSI). Is there any possibility of using an ATA100 or ATA133 controller under MorphOS?

PowerMac G4 MDD has Ultra ATA-100 onboard
( six units IDE : two ATA100, two ATA66, two ATA33)

Sonnet Tempo SATA PCI can be useful :

Is there a MorphOS driver for that SATA card or is it only an option under OSX?

Also, I know the Powermac have one built in ATA controller (two if you count that CD connection), my main interest in the ATA100;/133 contollers was to add more drives than can controlled right now.

The only supported controllers seem to be SCSI. SCSI drives are usually high performance drives and are more expensive than comparable ATA or SATA drives.

Does anyone have any idea whether or not we're likely to see support for additional drive controllers?

Hi,

I think It's at the moment only for OSX and OS9.x, but It could be useful in the future the support driver in MorphOS.

Also I think It's useful support in the future ATI Radeon 9800 AGP in MorphOS (2D and 3D).

Also CPU daughterboard Sonnet cards, these:

Isn't Sonnet the only company that makes CPU upgrades for the MDD models? The Encore/MDX G4 Duet you listed first.

Its stupid they don't have any single upgrades for MDD

Yes, that is dumb.
Considering that the biggest bottleneck in any Powermac is the memory, having two 1.8GHz 7448s on the same bus is silly (and expensive).
One 7448 processor at 2.0 or 1.8 GHz would cost less and still outperform most other G4 based Macs.

> two 1.8GHz 7448s

7447A, not 7448 ;-)

Ugh! Once again, Andreas proves me wrong on something.
Why (except to save money) would Sonnet use the lower performing 7447A instead of the 7448?
And how is it that I can buy a 7448 upgrade for a Quicksilver Powermac, but the only accelerator available for the MDD is based on the 7447A?

At this point the release of an out of stock PowerMac version has not even been confirmed on morphos-team.net yet. We're not yet sure which of the models can / will be supported. When it comes to 3rd party add-ons it's very unlikely they will be supported from the beginning, or even at all (unless some 3rd party does the drivers). This includes the add-on CPU cards.

Not a bad idea, actually. I wouldn't mind the challenge.
A disk controller driver would be far easier to write than the code supporting a different processor.

OK - Let me modify my inquiry. How about the likelihood of Symbios based SCSI PCI disk controller working in a Powermac?

Sure, especially because the CPU support has to be done in Quark while a driver can usually be a 3rd party component.

As for Symbios, it'll probably work provided you can find a card compatible with the MorphOS' drivers (which haven't been maintained in quite a long time).

@ jacadcaps

well I thought the idea behind having the Powermac support was to have a replacement machine for the Pegasos2 on which MorphOS run's? If that is the case then I very much hope that support for up to the fast 1.8 Ghz upgrade solutions will be done because IMHO we need a high performance machine also for MorphOS! If like the Sonnet ones would be supported it gives the user the possibility from 1 GHz, passing by the 1.6 Ghz up to 1.8 Ghz.

I'm all for support for the 2.0 GHz upgrades by Newer Technology and PowerLogix :-)

Thanks for the info! I did'nt know that this existed, I'm not familiar enough with Macs...
Of course such un upgrade would be GREAT and very much needed IMHO. I say it again we would need a high performance machine for MorphOS to replace the Pegasos2!

In theory it should work. If as you give the appearance of, Morphos can read the Symbios pci card the Morphos drivers can and should work. This is cool. we actually have 1 Symbios 895 PCI uwscsi card and 1 Symbios (LSI) 810 FastScsi board in stock if anyone is interested. Guaranteed to work with Morphos! the Symbios 895 driver is rather excellent. I think Laire himself wrote the drivers for symbios scsi? The 895 driver with a Symbios card yiels theortic 80mb/sec!! I have extensively tested Symbios drivers with morphos and Peg1 and Peg2 because a lot of the systems we sold back in 2003+ people wanted SCSI boards installed compatible with Morphos (and linux too btw) for legacy Amigas OS Scsi drive usage!

I have a Symbios SYM8952U board. I'm not sure if this works with 895 driver, but I'm going to give it a try.
