So I've basically finished most of my upgrades on my 7600 project. It has a gig of RAM, a 1 GHz G4 processor, Radeon 9200 graphics, two USB and two FW ports, and a total of about 375 GB of storage (between an "SSD" which is an mSATA/IDE solution and a 7200 RPM HDD hooked into a Sonnet Tango PCI card), partitioned into nine volumes running 7.6.1 to Tiger and a lot in between (also 8.1, 8.6, 9.1 and 9.2.2). Two of the volumes are for shared storage and backing up the other drive, and one is reserved for a Leopard project. Has anyone successfully installed Leopard on one of these old Macs (7300-9600 family)? Tiger was a breeze; Leopard looks like it poses some real challenges. I've heard it's been done, so I carry on and persist. (Not expecting a good user experience, but this is a hobbyist's "because I can" thing. It runs Tiger decently, but not great since the 50 MHz system bus is a bottleneck.) There are a couple of challenges, at least. One is that Leopard needs to boot from a DVD (and these old Macs can not boot from FireWire so using Target Disk Mode from my Pismo or TiBook is out). Are there any bootable DVD drives for these models? I have an external SCSI Yamaha CD-RW which works well to boot externally (sometimes with help from XPostFacto), but it doesn't do DVDs. Another challenge is that the installer for Leopard might not want to install on this model (Leopard Assist may be able to help here, but I think it's a problem if I need both LeopardAssist *and* XPostFacto, since both of them do their own editing of NVRAM before rebooting). I've tried using SuperDuper to clone another good, "fresh" Leopard install on a FW drive to the target volume and boot it with XPostFacto, but it fails, too -- I get the Apple logo but never get to the spinning wheel below -- it just hangs there.
