    Hi guys,
    This my little help for MorphOS team for new incoming MorphOS 2.x for PowerMac G4 :-)

    I have recived in these days some interesting graphic cards AGP flashed for Mac OSX 10.3.x, 10.4.x, 10.5.x and OS9.2.x ... and now I have found all needed to proceed in the right flashing.

    I have used a new Sapphire ATI Radeon 9250 AGP 256Mb 128bit, flashed it and verified it in PowerMac Quicksilver G4@867 and in PowerMac G4 MDD Dual G4@1420.

    details, what yout need:
    1) This new card : http://www1.sapphiretech.com/en/products/graphics_specifications.php?gpid=59
    2) flash it with this ROM http://themacelite.wikidot.com/local--files/wikidownloads2/R9250_127_reduced.rom.zip in a x86 PC.
    3) http://themacelite.wikidot.com/pins-3-and-11 (with scotch for exemple for Quicksilver and MDD PowerMac G4)
    4) http://themacelite.wikidot.com/9250-trick (resistor mod is needed)
    5) driver http://strangedogs.wikispaces.com/file/detail/ati-aug2005-radeon-universal-rom-update.dmg.zip for OSX version (tested OK 10.3.x Panther, 10.4.x Tiger and 10.5.x Leopard) and here the driver for OS9.2.x http://www.applemacanix.com/9200os9/9200os9.sit

    All perfectly OK, I use now all Macintosh screenmode with OSX 10.5.x, 10.4.x and 10.3.x and OS9.2.2
    All other is ok (es. Open Firmware APPLE+ALT+O+F and boot screen mode Macintosh for bootstrap OS) all It's promoted correctly in DVI and also in VGA output connector.

    (Only "little problem" at the moment is that with the driver "ati-aug2005-radeon-universal-rom-update.dmg.zip" the graphic card 9250 256Mb is seen in OSX Apple System Profiler as Ati Radeon 9200 and with 128Mb, not 256Mb, (also the same with OS9.2.x driver/extension)but I think with the right driver MorphOS you could be use in the future also the 256Mb in MorphOS).

    I hope these informations can help you a little in the porting of MorphOS in PowerMac G4 and if you need I can try something (I have many of these cards here to test)

    best regards

    My PowerMac G4 is the only system in the house that uses AGP graphics cards. All of the x86 PCs either have an integrated chipset and a PCI graphics card or PCIe graphics card. What would it take for me to buy an already converted graphics card? :-?

    @Samurai_Crow
    this is a simple way to update the PowerMac G4 with a graphic card well supported in MorphOS (2D and 3D), and in OSX.
    (I use the same card (not flashed) with Pegasos2 and MorphOS/OS4.1.1/Linux).

    @Divinity

    I understand it is simple. I just don't have an x86 PC with an AGP port to reflash it with.

    Hi,

    Can I follow this procedure with a PCI version of Ati 9250 256 MB ?

    number-one,

    Yes, there is a Mac version of the 9200 PCI card. Follow the basic instructions mentioned by Divinity (except, obviously, taping pins 3 and 11).

    Samurai_Crow,

    >I understand it is simple. I just don't have an x86 PC with an AGP port to reflash it with.

    As I've already done this for a couple of other users,
    I might as well offer to do it for anyone.
    PM me and I'll send you my address. Shipping a card to me (in the US) only costs about $5.99 via Priority Mail.
    Send me your compatible PC video card and I'll re-flash it for Mac use. Then I'll ship it back to you.
    MorphOS users only.

    That's OK Jim. I've now got a Pentium II motherboard with AGP socket and power supply that I can use to reflash the graphics card. Now my problem is more financial. :-)

    be careful. If that motherboard uses a 2X AGP slot there are a lot of AGP cards you won't want to plug into it.



    Otherwise, the offer still stands for anyone else stuck in this situation.

    number-one,

    yes, here http://themacelite.wikidot.com/wikidownloads2 some ROM for 9250/9200 PCI (useful in all PowerMac G3 and old model PowerMac G4 not AGP)

    Divinity :
    I will add an ati radeon 9250 PCI 256 MB in a Power Mac wich has already an ati radeon 9000 AGP. For use two monitors with MorphOS.

    I'm not sure anyone has gotten a dual video card system to work correctly yet.

    MorphOS can't handle two Radeon cards at once.

    Numerous working dual graphics card setups have been reported here on MorphZone over the years, at least with Pegasos. According to pega-1 it should work with PowerMac as well:

    It's just that a Radeon/Radeon combination must be avoided, as jacadcaps says.

    I'm confused by that Andreas. You mean a Radeon AGP 92xx and a PCI 92xx wouldn't work, but an AGP 92xx and a PCI Voodoo3 2000 would?

    Yes, that's what jacadcaps said in this very thread, and also what pega-1 said in the posting I linked to (and also explaining the reason why). While with the Pegasos it's important to have the Radeon in the PCI slot it's my understanding that with the PowerMac it doesn't matter whether the Radeon is put to PCI or AGP.

    Afair Apple's OF initializes both PCI and AGP cards with a Mac ROM, so Radeon PCI and an AGP Voodoo should work as well as an AGP Radeon and a PCI Voodoo combo. Rage + Radeon should work too ;)

    Thanks, I've got a old Rage128 PCI around here somewhere, the Voodoo3 2000 I've got is a PC card though.

    My Voodoo PCI surely doesn't work correct in my powermac, tested it in both a digital audio and a quiksilver. Both standalone as well as dual monitor setup

    Is there an Apple ROM for Voodoo cards?

    A PC-rom Voodoo won't work with OpenFirmare and OSX but should work fine in MorphOS.

    I have the mac rom for voodoo 3 2000 and voodoo 3 3000.

    I flashed a voodoo 3 2000 PCI with PC under MS-DOS but I didn't test it on power mac for now.

    Can you tell us where you got the ROM file or share it with us?

    Well I have a voodoo4 pci pc-version ... I does get recognized by Openfirmware because I do get some vision in MorphOS ... only the colors are VERY wrong. I made a topci about this problem a while ago and if I remember well, I did send soem screenshots.
