Haven't been around since my iBook G4, iPad and iPhone were stolen as part of a break-in last Fourth of July weekend. Settled on a nice mid-2009 MacBook since then. I also emptied a storage locker that I hadn't visited since 2007 and brought home an iMac G3 DV 400MHz that I've been playing around with. Maxed out the RAM to 1GB and installed AirPort. Fascinating to see it connect to the 'Net and actually load many pages without too much pain. I played a YouTube music video, and though the video was choppy, the audio worked just fine. I mean, it's fifteen years old. I was into the G3s back then and did all kinds of great and sometimes crazy things with them, but my memory has since faded and I need some help. I'd partitioned the HDD with OS 10.3.9 Panther and OS 9.2.2. What I'd like to do is junk the OS 9 partition and have the entire disc available for OS X. Looking to upgrade to Tiger, but the retail disc is still very expensive. I still have the OS 9 disks and have backed up any files I want to keep for it in case I want to revert back to OS 9. I'm pretty confident in what I need to do, but I don't want to make a catastrophic error. Any and all help would be greatly appreciated. Edit: Short of trashing the OS 9 partition, is there a way to disable it on startup?
