I gathered a little how-to here: http://tyom.blogspot.com/2009/12/solaris-under-qemu-how-to.html If the patches will made it into 0.12, I think it's worth to mention OBP and kadb boot support as a new feature. What do you think? Actually the shell-boot is also pretty close. We just need to fix the NF-bit handling in MMU. I'm experimenting with a real SS-20 to understand how it is supposed to work. (the MCC manual doesn't describe it clear enough, as you have pointed out before). -- Regards, Artyom Tarasenko solaris/sparc under qemu blog: http://tyom.blogspot.com/
