Unfortunately not. The 8111 chipset on the Serengeti Cheetah is open, but they aren't available any more in real life. Everything else is still closed, but hopefully not for ever.
we can get v3 up on simnow with old chipset, I am hoping to find an amd-based board with newer chipsets.
The problem with SimNow is that it only works on x86-64 machines. I do all of my development on my x86 (32bit) laptop, so if I ever want to test an x86-64 v3 port, I have to get an extra machine anyway. Hm.
I'd really like to have us port existing support for a chipset from v2 to v3, so we can compare settings in case something goes wrong. Now for choosing the chipset: - Nvidia is pretty much ruled out if we want any chance of data sheet access. - SIS have contributed code, but I don't know about data sheets. Besides that, it is very difficult to buy a board with any SIS chipset (in Germany). - VIA is a possible target because we already have some code in v2 and at least one person has access to their data sheets, but they require an NDA. Plus, boards with the chipset are rather easy to buy. - AMD may work out in the next few months... RS690 data sheets (register reference guide) are publicly available, but SB600 is pretty much secret.
Marc: Any idea whether the process of publishing the SB600 data sheets is handled by the same persons who are currently occupied with cleaning AMD/ATI Radeon data sheets?
