Does anyone here know if the AGP Radeon 9250 128mb VRAM from my Efika will work in a G4 PowerMac (in case I decide to get one and it has a non-supported video card in it when it arrives)?  I read somewhere that the video cards in Macs have different firmware in some of the Mac models.

I might retire, or sell my Efika, after I confirm that it does not have a hardware failure with it's RAM chips.

Steven Solie hinted at the AmiWest speech that the secret project Hyperion is working on is a hardware-related project.

I doubt that it will be a Mac-related thing though.

I hope you are wrong.  I would love to see AmigaOS4.x advanced to SMP (said to be on their road map) and running on a dual G5 PowerMac at 2.5GHz.

With that level of PowerMac I could get by without my 3.0GHz Quad Core PC and have one less computer to mess around with.  I mean I think for what I do with a computer, I could probably be satisfied with AmigaOS4.x, and/or MorphOS2.x, plus MacOSX, or Linux on the dual G5 PowerMac at 2.5GHz.

Here I am logging in and posting from my Mac Mini (1.5GHZ, 1 GB ram, 80 Mb HD ,64 MB vram)!!!
MorphOS install later this week-want to make it dual boot.

This is my second craigslist mini-first one was a disappointment as that seller misrepresented the memory and condition and insisted on meeting in a public place  where incidentally we couldn't plug it in.I failed to pay enough heed to CAVEAT EMPTOR!

 Now I wonder if the Powermac port of MorphOS will use bigger vram or what other advantages it might have over this mini.At 1.5GHz it is actually faster than my current stable of Powermacs.

Congrats on getting your 1.5GHz G4 MacMini!  I love using MorphOS2.4 on mine.  The 1.5GHz MacMini is likely to be the fastest way to run MorphOS for a while, as the G4 PowerMacs that MorphOS is going to support were only released with 1.42GHz G4's as their fastest option.  Of course they have two G4's, but MorphOS can only use one of them, so unless there is some other part of the PowerMac's hardware design that will speed up MorphOS, the 1.5GHz G4 MacMini will remain the fastest MorphOS machine.  There are upgrade processors for the G4 PowerMacs that can increase the clock speed up to 1.8GHz, or 2.0GHz, but they are expensive new and hard to find used and it is not clear which ones, if any of the third party accelerator G4's for the PowerMacs will be supported in MorphOS, so I would wait until it is released before going out and buying one of those faster G4 cards for your PowerMac.

As for better VRAM capabilities, if you can find one of the already MorphOS supported 8500, 9000, or 9250 Radeon cards that is also supported by the PowerMac and has 128mb, or 256mb of VRAM, then you would have a better graphics card for MorphOS to run on, but the original graphics cards that were available for the G4 PowerMacs and are also supported by MorphOS only had 64mb of VRAM just like the G4 MacMini.  I am talking about the ATI Radeon 9000 Pro 64mb AGP graphics card that was an option at order time for many of the G4 PowerMacs.  I know that better graphics cards are available that will work in the G4 PowerMacs, but have not researched which of those are also supported by MorphOS yet.  Instead, I picked up a 64mb ATI Radeon 9000 Pro AGP card that had been pulled from a G4 PowerMac when it was upgraded for next to nothing and I am holding on to it, waiting for an insane deal to come my way on a Dual G4 1.42GHz MDD PowerMac.  If the MorphOS team finishes work on getting MorphOS to work on a G4 PowerBook before I find that insane deal on a G4 PowerMac, I will just sell this 9000 Pro 64mb graphics card to another MorphOS user that needs it for his G4 PowerMac that they bought with an unsupported graphics card.

Enjoy the blazing speed of your 1.5GHz G4 MacMini and MorphOS2.4.  They are a great combination.  I hope you think so too and will register MorphOS, if you haven't already done so.
