Thanks everyone Im going to look into this, go shopping, and do something eventually. In all honesty, I have to own up to a blasphemy and confess that Im not running a Mac OS on this box, Im running Lubuntu 12.04 Ppc, so I dont know if that changes any of the booting parameters or not. I do know that all the Linux distros I've tried boot off the native "yaboot" and don't replace with another boot loader.
Ive posted about this machine here before. When I bought it at a garage sale for $20, it had Mac OS 9 installed and you could clock the response time with a sundial. I wiped the hard drive and have experimented with several Linux distros all of which run decently (some better than others the fastest so far is Mint Linux Ppc, but with my weak skills I cant keep from nuking it back to a command line interface). But all are just a tick slower than Id like - wouldnt we all like our computers to run faster? Anyway, maybe if I had been able to reinstall OS 9 I would have seen a difference, but I didnt have the disks.
I like Lubuntu on this machine; its very stable and I havent been able to kill it yet. But as I had always understood Macs were supposed to run faster than similarly powered PCs, this one has always been a bit of a slug, and yes, I do understand that I only have a 450Mhz. processor here. It was suggested on this forum that perhaps my hard drive was worn out and a replacement might improve things ergo, this post. Success or failure, Ill post my results and hopefully well all learn something from it.
