Well, I decided to do a wee bit of experimenting.....probably repeating experiments I made before, if the truth be known!
Following the recommendations given in the "How to.." section at the top of the front page, I tried both RosaImageWriter AND Unetbootin.
For me, RosaImageWriter wouldn't behave itself. No matter how many times I started off with a pristine, FAT32-formatted flash drive, it kept overwriting the drive with an "unrecognised" filesystem and not writing anything. The first time it did this, I wasn't too fussed; I know older versions of gParted don't recognise ISO9660.......and I know for a fact that Rosa simply uses 'dd' for its operation.
For this test, I was using the Xenialpup 7.5 32-bit ISO image. It's "old reliable", and never fails to work.
I tried booting from it. It couldn't find the Puppy SFS main file........sounded familiar.
So I reset it all up again with Rosa, twice more.....making sure to redo the drive with a fresh, clean MBR just to make sure. Nada. Zilch. Absolutely nothing.......the drive wouldn't even mount afterwards, because there WAS no file-system there.
I gave up on Rosa.....and turned my attention to UNetbootin.
-----------------------------------------------
Now, this could all have been because I was running in my custom re-master of Slacko 560, where I've been all afternoon. I seem to recall 64-bit Rosa worked for me when we were testing stuff for @wizard , but the 32-bit build simply didn't function the way it should have done. So I may not be the best tester with this set-up.
Anyway; I tried UNetbootin. As it comes, OOTB, Xenialpup wouldn't boot from this either; again, couldn't find the main SFS file....
I mounted the ISO. I edited the isolinux.cfg file to change every instance of
.....to
I then re-built the ISO with jrb's marvellous pupbuild_tools suite. Redid the flash drive with a fresh format of FAT32 and a new MBR, then ran it through UNetbootin again. And this time, it booted straight up, AND allowed me to create a save-file (not -folder; remember, this is FAT32 here) then shut down, happy as Larry.
-------------------------------
So; I'm a-wondering, now. Might it be an idea to modify the isolinux.cfg file in future Puppy builds to use "pmedia=usbflash" rather than "pmedia=cd"? Very few machines now come with a CD drive; USB is almost universal today.
Food for thought, perhaps? Might make things easier for noobs in future.....
Posting from it now with Slimjet-portable.
