[OpenBIOS] [PATCH] SPARC64: configure the Sabre PCI TAS register

[Peter Firmstone]

There's a lot of cheap sparc hardware based on sunv T2 coming onto the market, I'd like to use AMD cards that are known to work well with the free radeon driver, but none of them have open firmware support.

I've read that IBM's OpenFirmware did include vga bios emulation.

I think the openBoot firmware at the link is for the T1, Sun also released a later version for the T2 sparc processor, which is still available.

They released their hypervisor code too, I don't know it's portable to other architectures, but it's pretty cool technology. 

Thanks,

Peter.
