So…my service to my new church is utilizing my design skills (such as they may be). But, until just a week or two ago I've been down to the iMac G5. I've futzed with the QS a bit once in a while ever since it just stopped booting way back in July or so. That GigaDesigns dual processor is nice, but tempermental. So, cutting my losses short I decided to put the Sonnet 1.2 single back in (the processor that came with the Mac) and…same thing. Chime, but no boot. Futz around some more. Now, back in July (or whenever it happened) I also removed the fan off the ATI card and put in a fanless cooler borrowed from another identical card. This is an ATI 9800 Pro. I KNOW the Sonnet is good, so I decided to bang a bit on the ATI card. Low and behold! Boot!!!! So. NOW, the plan is to do what I need to do. I know the Sonnett is stable. Once that's done I'll probably try the GigaDesigns again and see what happens. For those that were following, the fan I stuck in the bottom seems to be doing a pretty decent job. The IDE drive in the ZIP bay is around 108º as is the boot 1TB SATA drive and the WD Green 1TB drive is around 99º. Going to have to look at the USB card though as I don't think it's playing nice. My two external 500GB Time Machine drives are not being recognized (they are USB). But it's nice to have the QS back up at least! Now if Dropbox would just finish hurrying up and updating files!
