I guess it's time for a progress report. Or, perhaps rather a lack of progress report...
I decided to try the CD option. Using the CD unit of my test rig (Acer Aspire 3100 with 512MB RAM) failed (despite beeing able to play CD music and open various files), and instead of troubleshooting I opted for my trusty old Dell Latitude D610 with 2GB RAM running Linux Mint 19.3 Cinnamon.
Before downloading a fresh new .iso file I decided to try the bootable USB that wouldn't run properly on my test rig. It started up without problems, it set the right screen resolution all by itself and the Light Web Browser was present. I wouldn't say it ran at lightning speed, but for a 15 year old laptop it was not all that bad.
Next, I downloaded a fresh new .iso file and created a bootable CD. I tested this on the Dell as well, and it ran as it should, allthough slower than with the USB. That would of course change once it was installed.
Back to the test rig with a fresh new bootable USB and a dito CD. First run was with the USB. The results were exactly like before. No browser and impossible to set the screen resolution.
So, my last hope was that the CD would do better. And it did. Sort of... The browser WAS present this time, but it took almost half an hour to start up. I have yet to find out how much faster it would be once installed. The screen resulution was still impossible to set.
Since the USB version ran reasonably well on the Dell, which is about 5 years older but has 2GB of ram rather than 512MB, I set out to try to find out if there might be something wrong with my test rig. It runs the Lubuntu it came with reasonably well, so there are no immediate reasons to suspect that there should be something wrong.
The first test was to try to install Linux Mint 19.3 Cinnamon, since I alrady had a bootable USB. It shouldn't be possible, since the minimum requirements are 1GB of RAM, and allthough it started off quite promising, eventually the startup came to a complete halt.
Next I tried with Zorin OS Lite. It has a minimum requirement of 512MB of RAM. It completed the loading process, but when I tried to start the browser it got stuck in 100 % processor load. I was happy enough that it loaded properly and suspect that it would perform better once installed.
My third attempt was Slax. It loaded without problems, but again, when I tried to start the browser, it stalled.
My conclusion thus far is that there is probably nothing wrong with my test rig, but it is on or near the limit of what many of the lightweight Linux distributions require. As for BionicPup32 8.0, it is probably the fastest among the ones I have tested, and possibly also the most feature rich out of the box. There's only on minor problem. I can't get it running properly!
From the onset of this quest, It has been my intention to find out just how old hardware can be given a second life using lightweight Linux distributions. Throughout the process I have come to the conclusion that my "last stop" on this path will be Tiny Core Linux. Before I go there, I would like to exhaust my other options. So I'm now open to suggestions or answer to some questions:
Is it possible in some way to get BionicPup32 8.0 up and running on my test rig?
Is there another Puppy version that would serve me better, and if so, which one would that be?
Is there another distribution alltogether that would be a better choice for me?
I will eventually upgrade the RAM of my test rig (it's upgradable to 4GB), but doing so right now would defeat the purpose of my quest.
