Perhaps we'll be getting some OS4 drivers for newer hardware now?

Ehh no? They released some GPU specs. 2d only at this point but 3d specs coming out in a bit. RC630 Register Reference Guide M56 Register Reference Guide And a reference R500/600 driver next week that can also be mined for information since the guides above are just register listings. |

Now would definitely be a good time for PCI-Express Amiga hardware to arrive. AFAIK, the most recent card that can be put into an A1 (without an expensive PCI-to-PCIe riser) is a Radeon 9800. Hans |

I found these as AGP cards as well: X1950, X1650, X1600, X1550, X1050. No idea what chipsets they are using though, could not find that info on their web page in a quick search. http://ati.amd.com/products/radeonx1950/specs.html http://ati.amd.com/products/radeonx1650/specs.html http://ati.amd.com/products/radeonx1600/specs.html http://ati.amd.com/products/radeonx1550/specs.html http://ati.amd.com/products/radeonx1050/specs.html Edit: Also found 2400/2600 AGP cards. http://ati.amd.com/products/radeonhd2400/specs.html http://ati.amd.com/products/radeonhd2600/specs.html Swedish shop selling the above cards in AGP form: http://www.komplett.se/k/kl.aspx?bn=10413 |

Unfortunately they're AGP 8x only, which means that they use lower voltage signaling than the Amigaone AGP bus does (1.5V instead of 3.3V). Hence, putting one of these in your machine, would fry stuff. Hans |

Ok, so that would be usable for now. I assume that it plugs into the PCI 66MHz slot. Would it be possible to have both an AGP and a PCI-66 card plugged in and just switch between the two? That would enable experimentation without having to swap cards all the time. I remember there being a discussion about the 66MHz PCI slot, but I don't think that there was ever a conclusion about whether it could have something plugged in at the same time as AGP. Hans |

I wouldn't know if you can plug in AGP and PCI-66 together. I would imagine it'd work find in a 66 slot. If not, plug it into a PCI-33 slot instead. As for switching between them, I don't know that too. I just swap cards installed, I've never had two together, habit from early on when that definitely would not have worked, but I don't know if that's changed or not. Realize that the PCI vendor/device IDs need added to the list before they will be recognized, without that the computer doesn't know to try the Radeon driver on any card. That's my current problem with my A1, I need to swap in an older card in the list to install OS4, start over, edit the list to add my X1950, and then try that card again. Right now all I get is a message that no known graphics card was found to run an OS4 driver, but I do see that printed on the screen connected to the X1950. :) Ugh, if only I had time to fiddle with that stuff. |

I guess I should have gotten around to implementing the idea I had to allow you to specify board information from UBoot to be passed to PCIGraphics.card to permit it recognize a card it to doesn't support natively... |

Not having the vendor/device ID in the list could actually help someone working on a driver, or a new graphics system (which is on the card). That way they're not competing with the existing drivers for access to the card. A test scaffold could be built allowing the driver (or parts of it) to be tested without swapping hardware, and with the other graphics card still available to look at debug info and edit code.

Hmm, does all this mean that you can't use 'any card' in VESA modes on os4? If so then one wonders why there has to be such an artificial limitation. Is this because of UBOOT or OS4 itself? I was under the impression that UBOOT had an x86 emulator that used the BIOS on gfx cards to initialize them. |

Right now, no-one's written a VESA driver for OS4 (at least there isn't one released yet). If someone wrote such a driver, there wouldn't be an issue. IIRC, this is what Scitech's SNAP driver was supposed to do. Hans |

Ahh I see, would be nice with a VESA driver then. |

why vesa? ain't it old and crappy? and even if we had that, ain't 2d fast enough on radeons? my radeon 9250 is doing an ok job at 2d. and why should i stick in a board there that only has support for 2d? this is only said with the desktop market in mind. as this is the only existing market. |

Old radeon cards won't be around forever. Having VESA cards means that you can put any card in there and get a picture to start working from without worrying about if specific drivers are available. Plus is helps when developing new drivers without requiring that you have access to a card with specific drivers. It's not about performance, it's about basic support. VESA is the driver all other OS'es adds first to support the most wide amount of hardware from day one. I don't see why amigaOS has to be different about it. |

I look at the specs of the rv650, and its a huge register set and will not be done in a short time frame (Atleast if I should do it). But ofcoarse now that the specs are open its proberly will be done at some point. RWO |
