If you read the context around these warnings, what is not supported is saving sessions to cd. Cd's themselves work fine. Just like you can still play old music cd's on a new dvd player -- even hd-dvd! Cd is still a perfectly acceptable boot as well as live-session medium.gcmartin wrote:I would suggest to everyone to heed both @JamesBond, @Kirk, and @TaZoC's advice to USE DVDs... and is a reason the distro authors indicate that they DO NOT SUPPORT CDs for media use with their ISOs.
Slacko64 is not uefi bootable. What this suggests is that while your box IS legacy bootable, it doesn't support the newer uefi firmware boot process (the date, ca2006 is a dead giveaway!). I imagine you also have no problem with the original lighthouse uefi flash installer. It doesn't work on many (including my) machines. I had to go to the woof-ce universal installer script (the original is still available in the menu).
Try isomaster on the slacko64 iso, replacing the system files (vmlinuz, initrd.gz) and basefile (puppy_slacko64_5.9.1.sfs) with those from JL64, edit isolinux.cfg to suit (don't forget to replace initrd.gz with initrd.xz) and see how far you can get in the boot process.
If you have any success, we can make a truly retro iso for truly older 64 bit boxes!
