I shall call it “Frankendrive”
Posted on July 6th, 2010 by KennethSo I needed to install OS X 10.5 (Leopard) on my PowerBook G4 today, as I would very much like to be able to play through the Ultima 6 Project. I actually tried to play it last night, but it quite consistently crashed not two seconds into the introductory sequence.
Apparently, the mod requires Leopard. I have Tiger (OS X 10.4) installed at present, or I did until this afternoon. Until now, it has served me well, but it’s not like I mind having an updated OS at all. My brother had spare Leopard discs on hand, and was quite happy to drop then off at the house last night. All I needed to do was back up a few files (just to be safe) and install the update.
Or so I thought. I forgot one thing, however: my PowerBook’s DVD drive refuses to read DVDs. It will read CDs just fine, which could mean that the laser glass needs polishing, but…well…I just don’t feel like prying the laptop open for something like that right now. The time investment required is…significant.
But I digress.
I backed up my files to an external hard drive and asked around the office as to whether anyone had an external DVD drive. I know we’re supposed to have one, but nobody was sure where it was. I had just deleted my (metastable) OS X 10.6 virtual machine, as well, so the option of imaging the DVD to a USB stick on my Windows computer was out of th question.
I did, however, have that external hard drive.
If you think about it, all an external hard drive is, really, is a hard drive with either an ATA or SATA connector (data and power) and a small circuit board that bridges between that and a USB connection. Oh, and a pretty case. Hard drives and optical drives both use either ATA or SATA to connect to a computer when installed internally…so I reasoned that a hard drive case should work to connect a run-of-the-mill DVD drive to the PowerBook. A quick bit of scrounging around the office turned up an unused ATA DVD drive, and it jut so happens that the Vantec hard drive I had just finished using to back up my data was in an ATA-specific case.
Ideal!
And yes, the OS X install DVD mounted correctly once I plugged this thing in. Not that I really doubted that it would — an ATA-to-USB interface should, properly, be totally agnostic as to the exact sort of ATA device it is connected to; it should just facilitate communication between that device and the OS on whatever it is being connected to. And it did that quite marvelously, I must say.
Of course, mounting the DVD is one thing. Booting from it, which is required to install the OS, is something else.
It’s funny, I think, how the firmware that is running in the above draws it’s basic interface appearance from the “classic” Mac OS design school. This is the boot menu on a Mac (or, at least, on a PowerPC Mac); the USB drive is not the primary boot device, but can be selected as the one-time boot volume.
Of course, installing the OS is only half the battle; the updates that typically follow an install are usually the longer and more tedious part of the process. We’ll see, I suppose.
Anyhow, there it is: a thrown-together, impromptu external DVD drive, the Frankendrive. Ingenuity means that it works, not that it’s pretty.
