Prometheus PCI supported by NetBSD

[billt]

However, only non-DMA cards are usable, due to hardware limitations of Prometheus.

I thought the DMA improvement was done long ago. Why was it never released?

Will you release your Radeon driver for 68k classics?

That's more a question for Joshua. I worked on things, but I don't have ownership of them. He'd have to check the paperwork about being allowed to or not, if our contracts with others might be a barrier to that. Also, we never made a 3.x driver. Though at the start 4.0 was 68k, I'm not sure how things would move over to 3.x. Might be easy, might be hard, I don't know.

a) a 8086 emulator for common x86 pci cards

Early Radeon PCI cards wouldn't need an x86 emulator, we parsed the BIOS information tables directly per ATI's instructions. I believe their organization may have since changed, I'm not sure if things are the same now or not. I've heard mention of the Atom BIOS for Radeon now, but I don't know what that is or how it compares with early Radeons, and I don't remember what the newest Radeon we used in the classic PCI slot was. I had an original (befor enumber scheme) Radeon PCI and a 7000 I think. Most of what we used was AGP in the XEs, so I'm not sure if 8K or 9K BIOS series was the same either.
