Hi Fellow Mac Geeks, Just installed Panther on my 17" PowerBook, with 2 external FireWire drives. All systems go. After reading some of the posts on this list and cruising the boards, I was ready for the worst. Thankfully no such issues occurred. I have two external Western Digital 7,200 RPM FW drives (80Gb and 120Gb) daisy chained off Big Al's right FW port (and my iChat camera plugged in to the FW slot on the last empty drive...). I ran Norton System Works 2003 until there were no issues (on 10.2.8), and optimized the internal disk. I disconnected the FW drives, booted from the CD and took the Archive and Install path. Not a hiccup. I also run a 20" Cinema Display, a two-button wireless Logitech mouse and an external (Apple) keyboard. Dare I say this, but things could not have gone smoother. None the less, it's always wise to take those precautionary measures. Thanks for the tips and posts everyone. BTW, Panther is sweet. My zippy 1GHz feels even more zippy.
