Flash, you posted on another thread --can't find the post-- that you might want to wipe XP and just use a Puppy if there was one that would function on a computer with only IIRC 384 Mbs of RAM.
jamesbond posted on the 'old forum' about running dpup-stretch (in a virtual environment, no less) with only 256 Mbs of RAM. foxpup found the post and I copied it here, viewtopic.php?p=1320#p1320.
Inspired by jamesbond, while exploring the effects of 'stripping' to create a 'bare-bones' Puppy, I created a remaster of radky's Busterpup. It ran on my Asus 701SD which only has 418 Mbs of RAM. The remaster is still available, linked from this post: viewtopic.php?t=692.
[The post indicated that I intended to remove it from mediafire. Ideas fly bye. Actually doing something requires an effort.
And mediafire isn't complaining
].
The post may suggest some applications you could use. But it will also point out that the real problem with only a little RAM is that web-browsers are RAM-hogs. Disregarding caching and buffering, pupsys-info reported that the Asus still had 325 MB Free RAM on bootup. But:
"Closing that and starting palemoon, pup-sysinfo reported
Actual Used RAM: 177 MB Used - (buffers + cached)
Actual Free RAM: 241 MB Free + (buffers + cached)
Closing that and starting Mike Walsh’s Seamonkey 2.46 portable, viewtopic.php?p=2206#p2206,
pup-sysinfo reported
Actual Used RAM: 151 MB Used - (buffers + cached)
Actual Free RAM: 267 MB Free + (buffers + cached)
Entering “Cats Images” into a google-search in seamonkey pup-sysinfo reported
Actual Used RAM: 408 MB Used - (buffers + cached)
Actual Free RAM: 10 MB Free + (buffers + cached).
Moreover, it was also reported that 8 Mbs of the 377 swap has also been used. It should also be noted that it took about 3 minutes to load the web-page; and after it loaded it took over a minute for pup-sysinfo to complete and display its report."
I wouldn't be too quick to remove XP. It wasn't a bad operating system. Functional web-browsers may not exist; and if they do are security risks. But there are many programs for it. Many of those programs have been published as window-portables. (These require no RAM when not in use). Most of those will run under Puppys using Wine. The portable-wine versions require almost no RAM when not in use (probably less than 1 mb, consisting of links to the external).
If it didn't require an effort, I'd experiment with bionicpup32. I have no reason to believe that in practice it would require more RAM than debian-based Puppys.
