Since upgrading to 10.3.5 and Final Cut Pro 4.5 HD I have been having no end of problems with Final Cut crashing on launch (solved that one here) and with "log and capture" freezing toward the end of a tape.
I decided to revert to using OS X 10.3.4, and attempted to install it on a new 200 GB Firewire drive I had laying around.
I started up using the Panther install disk, then opened Disk Utility, and partitioned the drive. Then I opened the installer and attempted to install OS X onto it. However the three partition icons for that drive all had the little red "stop" sign over them, and selecting any of those icons got me this message:
"You cannot install Mac OS X on this volume. You cannot startup your computer using this volume."
Quitting the installer and then restarting it made it recognize the partitions as bootable, and the problem was solved.
I found that the only way to install the Intel-Mac version of Tiger on a firewire drive is to reformat the drive with the GUID option set. Boot from the Intel-Tiger install CD and launch Disk Utility. Select the Firewire drive and "Partition". Click the Options button and select "GUID" then partition the drive however you wish.
