No Roms, just the CD. Don't remember exactly, but 9.0, 9.04 and 9.1 were working, 9.04 probably the fastest. The instructions were about enough, you had to make first a config to boot from the MAC CD, install it and then with a new config let the OS to boot - there's not a boot change/priority system. Picasso96 doesn't work right, there is a missing feature that makes the screen cut in two parts that are interchanged. I had no bigger problems, I gave an old UWSCSI HD without usually used partitions mostly to MAC to be on the safe side. Probably 1 GB, it took long enough to prepare.
