What are the best boot parameters to use for a frugal puppy install on a USB stick that allows
putting as much in memory as possible so it can run as fast as possible?
Also it would allow saving a session if only requested to the USB stick.
I was wondering what you may find to be the best for you doing this.
Thanks
In the boot loader menu config file entry.
For the save, have the pmedia= command as pmedia=usbflash
That makes it run in pupmode 13 and have options for how the save works available in Event Manager ->Save Session
The save file or folder is never loaded into RAM, it only is layered into the operating file system.
In pupmode 13 the save uses a save ramdisk to store new stuff, until you tell it to empty into the save file/folder, updating it.
Click on desktop save icon, have set time to update the save, or ask to save on shutdown.
A normal boot will load all of Puppy into RAM.
Do not have pfix=nocopy in the entry.
This tells it not to load the different sfs's into RAM
Just loads into RAM the basic operating system.
Any other pfix= entries have no affect on loading into RAM.
However, pfix=ram is telling the system to only load into RAM and not use the save file/folder.
The things you do not tell us, are usually the clue to fixing the problem.

This is not what I expected

Thanks.
Good information that concisely shows how to do it.
I was looking at the boot parameters which seemed to be complicated.
I was trying the different parameters to see how they affected mostly the memory.
I concluded what you so nicely put it and realized the same things you mentioned.
It's just a few things that are important for this.
You responded to this at just the right time and reinforced what I was thinking.
So that helps me a lot by working with this. What you mentioned was very clear to me now.
The only additional things I experienced was that I newly installed frugal BW on the internal drive
and the USB stick.
When both of these booted, I saw they contained Grub version 2.03.
This caused conflicts with especially the USB.
To make this work all the way I needed to upgrade the Grub on both to version 2.06.
Now it all works as expected.
