Following numerous requests from users I've prepared Sparc LiveCD based on osol-1002-125-ai-sparc.iso (see my previous post). Please remember that this iso is UNOFFICIAL version, I've created it only for my tests. With this iso you can test OpenSolaris on your hardware, AI tools or you can install system from this LiveCD manually, using steps from my old posts (i.e. you need to create zpool, copy all LiveCD contents to rootfs, disable live-media services, change vfstab and etc).
Temporarily iso is here.
