Thanks, rockedge. The link you suggested wasn't it. But it got me thinking again. Once I found it, I changed the Title in the hope the new Title will be easier to find. This is the thread now named "New 32 Bit Puppys for Low RAM", https://www.forum.puppylinux.com/viewto ... 47#p100547
lallyblue22, while searching for the above thread I ran across this bit of information I never remember. For Puppys to use the least amount of RAM add the 'nocopy' argument to the boot-stanza. To wit: in the DEFAULT boot stanza will be an argument such as this:
linux /bionic32/vmlinuz pfix=fsck,fsckp or
kernel /bionic32/vmlinuz pfix=fsck,fsckp
There may be other arguments on that line, such as pmedia=atahd. But we're concerned with the arguments given to pfix. Changing the above to
linux /bionic32/vmlinuz pfix=nocopy,fsck,fsckp [blue for emphasis only] or
linux /bionic32/vmlinuz pfix=nocopy,fsck,fsckp
tells Puppy NOT TO COPY the files in its core SFS into RAM.
The boot-loader grub2 starts the line with 'linux'; grub4dos with 'kernel'
When the 'nocopy' argument is used, opening applications will be slower because they have to be copied into RAM when needed. On the other hand, unneeded applications don't ever occupy RAM. You might want to try without the nocopy argument to see if it's really needed.
p.s. Re-reading this thread, wizard mentions that the 4-Series Kernels were more responsive than the 5's. Puppys are modular builds. It's easy to swap kernels. See this thread, https://www.forum.puppylinux.com/viewtopic.php?t=7832.
There's even an application (somewhere --it might be in Menu>Setup>Quickpet if you have Quickpet) that will do the renaming for you. But it only manages the zdrv.sfs. You'd still have to manage the fdrv.sfs manually. See the above post for this paragraph to make sense.
At any rate, for your purposes dpup-stretch still appears to be the Puppy to try first. For three Puppys slightly newer than dpup-stretch, follow the links on this post. viewtopic.php?p=4070#p4070. I don't recall liking any of those as much as dpup-stretch. The major advantage a newer Puppy would have has to do with accessing the web: newer Puppys will have newer versions of glibc, supporting newer versions of openssl. Openssl is the 'hand-shaking' system employed by all web-browsers and eventually websites will deny access to web-browsers not supported by reasonably current openssl.
