I re-partitioned my drives (unallocated: 10 GB; HFS: 5 GB; HFS+ 15 GB) and installed OS 9 on my second partition (one drive, 3 partitions, 30 GB total). I downloaded the ISO disc image for YDL 2.1 and tried to boot from the CD but can't. My machine keeps booting into OS 9. My setup: TiBook 500 Did I do something wrong? Forget a step? Thanks, Yisrael
