In another thread, I showed my recent installation of an SSD in my Cube. I used a dual 1ghz Quicksilver to set up the SSD before installing it in the Cube(due to the relative difficulty of accessing the Cube HDD). I split the drive into two partitions. I cloned the current Cube HDD(with Tiger and OS 9) via TDM. This partition boots both OSs and runs fine. I put a fresh Leopard install on the other partition. I ran set-up assistant and the 10.5.8 combo update from the Quicksilver, and everything seemed fine with that install. I finally tried booting it from the Cube earlier this evening, only to find that it would kernel panic while booting. I'm attaching a picture of the full screen text. I found several write-ups online of folks successfully using Leopard Assist or the equivalent Open Firmware tricks to install Leopard without any trouble, so it doesn't seem as though it should be possible without any real trouble. I would think that what I did would work, although obviously I went wrong somewhere. By the way, this particular Cube has a CD-RW drive(which I don't want to give up) so using Leopard Assist isn't really an option, although I suppose I could borrow the DVD drive from my other Cube. I could also do a Leopard Assist/TDM install from my other Cube, if running the install from a Cube is a necessity. Any ideas about what's going on here? By the way, if it's relevant-450mhz Cube, GEForce 2MX, 1.5gb RAM, and an mSATA SSD.
