Answer to: Why won't my G5 boot?There's a whole host of manuals available for macs, at http://www.eserviceinfo.com/ but for the G5, try this link at http://www.eserviceinfo.com/download.php.... It's a multi-part zip file, but it might help. Very detailed, with pictures. I've currently got a PowerMac G5 1.8 Dual-Processor with 4 GB RAM Maxed out, and I'm having problems with this booting up. I've got a bit of free time over the next week and over xmas so I'll give it a go and strip this down and figure out what's what.
