Whether puppy is booted from a CD or USB, syslinux.cfg invokes the display of the boot.msg graphic and provides a boot prompt where one can enter a puppy pfix=<something> command and after pressing the Enter key the puppy is launched. How is the puppy prefix command passed and to what?

I ask because in building a multi-boot puppy, I can enter the pfix command at the boot prompt but then the applicable puppy is not identified and the command will always apply to the default puppy. If I enter the menu-item number I can't also enter the pfix command. How can I pass the pfix command to the selected puppy?

The menu and bootloading is as with all puppies, not a Grub4DOS.

The syslinux.cfg works; it looks like this:

one option, which may not be exactly what you're looking for, is to add an extra entry for each puppy with pfix=ram at the end.

The option to enter the command line allows you to completely replace or modify on the fly the boot codes that follow (append initrd=). It only applies however to the default item.
If you want to invoke different boot codes simply make multiple entries in your menu.
I note that you are using “pmedia=usbflash” AND “pfix=copy”. You do not need “pfix=copy” as by default puppy loads the main SFS to RAM. (Your pfix=2 also should not be there)

By way of example say you wanted to boot Saluki on a PC that had very little RAM and wanted to use pfix=nocopy: create an additional entry as follows-

Hello,
Have Grub point to Grub.. LOL
@ my meownplanet signature link, (username: puppy password: linux) you will find my MultiPup .pet which does what you are asking to create a MultiPup ISO with Grub setup as you need.. After choosing your Pup, you get another Grub menu, where you can add bootcodes..
D/L it and look inside at how it works...
Or just use it to make your ISO.. Very Happy

Rename it to MultiPup_3.3.tar.gz to unpack it without installing the .pet...

Or have a look around my stuff!!

Belated thanks for your recommendation of Multipup. Unfortunately, I haven't yet been able to install it as I don't have an ext2/ext3 partition in my system and creating one on an external drive at this time is not convenient. (I am running puppy from a headless laptop). Furthermore, I am at a loss as to when I am using/not using the pupsave - still (embarrassed Embarassed

) though the Readme assures me the pet will prevent me from any folly.

If I format a 4gb flash drive as ext2 , place a puppy on it and install Multipup to it, would that work? With a puplet (e.g. slacko) in which the Multipup pet is installed, would I then run the creator from the menu? Must the puplets that creator needs to make the menu be on the flash drive or it doesn't matter? Sorry about these questions; asked only because there is no ext2 to try.

Hello,
Where MultiPup must be on an ext2/3 partition, because it created a huge directroy and would overflow a pupsave, and some of the scripts need to be run from ext2/3 to function..
However, the ISO`s you use can be anywhere, where ever they are, as you just (absolute) symlink them in to MultiPup..

While running your usual Puppy, you can just place (or install) MultiPup to the jump drive, so it runs from there...
After install, the menu entry runs a dialog to assist you in placing the directory, just direct it to the jump drive...
