pri,

If your SFS file is bigger than the available ram, then the SFS file won't load in memory.

If you want to be sure that it DOES NOT load into memory (even if enough ram is available) then you need to change the puppy "initrd.gz" startup file, since the "NORAM" option has been eliminated.

I think you may have to change the "initrd" code. As I recall, it is set at around 230M.

If you search for "COPY2RAM" in the "initrd" file and then look further for a test for "RAMSIZE", you could change "RAMSIZE" to some lower number.

I'm not sure why you would want to do this, and maybe I don't understand the question.

Cheers,
s

If you had a Linux swap partition I believe this would be used like ram although slower.

the init in woof already has the fix I proposed in the thread abushcrafter posted - you can build the initrd.gz with woof and manually swap it out using isomaster (just make sure your versions match ... 431 on init requires 431 in the sfs in /etc/puppyversion and /etc/DISTROSPECS)

thus far the only way to get woof is to download bones from the quirky repo on ibiblio and follow the instructions at bkhome.org/bones ... AFAIK there are no snapshot tarballs or anything (I think there is a howto in the forum as well)

Same problem I had with MediaPup, it tried to load a 320MB SFS file into 256MB of ram!
If you don`t have a swap Puppy doesn`t account for that, not good...
The pfix=noram is tossed out and ignored during bootup. I had to hack fix it to make it work.
