I got a PowerBook 5300cs from eBay that has no operating system installed (the listing did say it had no os). I have brand new Apple install disks for 7.5 (the original 7.5.0), but these will not install or boot because the 5300cs needs 7.5.2 or higher. I downloaded the 19 images from Apple's website of 7.5.3, but none are startup disks. I don't know how to install them without having a start up disk or an OS already on the 5300cs. I have Googled for hours and have gotten nowhere. The 5300cs doesn't have an optical drive so I cannot make it a cd of all 19 images. Is there a way I can get this thing up and running without having a real install set of 7.5.3 disks? I actually found a set on eBay last week but I fell asleep too early and got sniped.
