Here's the deal. I recently came into possession of a PowerMac G5, which came running Panther (10.3.4). According to those that I got it from, It was originally running Leopard, but as the rest of the systems that were being used with it were running Panther, The computer was downgraded. Now, as I am wanting to reverse this so I can get better use out of this computer, I find myself quite... Stuck. I Have a .DMG of Leopard on an NTFS Hard-drive attached to my Windows 7 Workstation, but as the hard drive is NTFS, I cannot simply just plug it into my PowerMac and expect it to work (Doing this actually crashes the computer, but thats another thing). Apple won't let me update to 10.3.9 either, as Panther is no longer in support, so I really don't have any way of getting NTFS support to access this drive, as it currently stands (NTFS Read/Write support was introduced in 10.3.9).
I Have tried putting the .DMG on a flash drive as well, but it is just under 7 GB in size, and the only file system accessible by both Mac and Windows is FAT32, which has a 4GB File size cap, Meaning that I can't move the .DMG via flash drive. Normally I would format my flash drive to the exFAT file system, which could hold this file, but support for this file system was only added in the Intel versions of OS X.
I've Also attempted burning the .DMG from my windows computer, as I was advised by many, but after about 2 hours wasted in PowerISO and 3 now-broken DVD+R dual-layer Disks, I'm still nowhere.
Any suggestions to getting this PowerMac of mine upgraded? I'm rather reluctant to purchasing a disk copy of Leopard from Ebay or Amazon, due to the cost probably totaling around 100 dollars, which I do NOT have right now. Provided I had a method of getting the .DMG onto my Mac from my Windows Workstation, I could burn it to a disk using Disk Utility, but again, provided that there is a way to move the .DMG in the first place. Thanks in advance.
